+# Changelog
+
+## Unreleased
+
+### Added
+
+- Added grad spike detection to the `edsnlp.train` script, and per weight layer gradient logging.
+
+### Fixed
+
+- Fixed mini-batch accumulation for multi-task training
+
+## v0.17.0 (2025-04-15)
+
+### Added
+
+- Support for numpy>2.0, and formal support for Python 3.11 and Python 3.12
+- Expose the defaults patterns of `eds.negation`, `eds.hypothesis`, `eds.family`, `eds.history` and `eds.reported_speech` under a `eds.negation.default_patterns` attribute
+- Added a `context_getter` SpanGetter argument to the `eds.matcher` class to only retrieve entities inside the spans returned by the getter
+- Added a `filter_expr` parameter to scorers to filter the documents to score
+- Added a new `required` field to `eds.contextual_matcher` assign patterns to only match if the required field has been found, and an `include` parameter (similar to `exclude`) to search for required patterns without assigning them to the entity
+- Added context strings (e.g., "words[0:5] | sent[0:1]") to the `eds.contextual_matcher` component to allow for more complex patterns in the selection of the window around the trigger spans.
+- Include and exclude patterns in the contextual matcher now dismiss matches that occur inside the anchor pattern (e.g. "anti" exclude pattern for anchor pattern "antibiotics" will not match the "anti" part of "antibiotics")
+- Pull Requests will now build a public accessible preview of the docs
+
+### Changed
+- Improve the contextual matcher documentation.
+
+### Fixed
+
+- `edsnlp.package` now correctly detect if a project uses an old-style poetry pyproject or a PEP621 pyproject.toml.
+- PEP621 projects containing nested directories (e.g., "my_project/pipes/foo.py") are now supported.
+- Try several paths to find current pip executable
+- The parameter "value_extract" of `eds.score` now correctly handles lists of patterns.
+- "Zero variance error" when computing param tuning importance are now catched and converted as a warning
+
+## v0.16.0 (2025-03-26)
+
+### Added
+- Hyperparameter Tuning for EDS-NLP: introduced a new script `edsnlp.tune` for hyperparameter tuning using Optuna. This feature allows users to efficiently optimize model parameters with options for single-phase or two-phase tuning strategies. Includes support for parameter importance analysis, visualization, pruning, and automatic handling of GPU time budgets.
+- Provided a [detailed tutorial](https://aphp.github.io/edsnlp/v0.16.0/tutorials/tuning/) on hyperparameter tuning, covering usage scenarios and configuration options.
+- `ScheduledOptimizer` (e.g., `@core: "optimizer"`) now supports importing optimizers using their qualified name (e.g., `optim: "torch.optim.Adam"`).
+- `eds.ner_crf` now computes confidence score on spans.
+
+### Changed
+
+- The loss of `eds.ner_crf` is now computed as the mean over the words instead of the sum. This change is compatible with multi-gpu training.
+- Having multiple stats keys matching a batching pattern now warns instead of raising an error.
+
+### Fixed
+
+- Support packaging with poetry 2.0
+- Solve pickling issues with multiprocessing when pytorch is installed
+- Allow deep attributes like `a.b.c` for `span_attributes` in Standoff and OMOP doc2dict converters
+- Fixed various aspects of stream shuffling:
+
+  - Ensure the Parquet reader shuffles the data when `shuffle=True`
+  - Ensure we don't overwrite the RNG of the data reader when calling `stream.shuffle()` with no seed
+  - Raise an error if the batch size in `stream.shuffle(batch_size=...)` is not compatible with the stream
+- `eds.split` now keeps doc and span attributes in the sub-documents.
+
+## v0.15.0 (2024-12-13)
+
+### Added
+
+- `edsnlp.data.read_parquet` now accept a `work_unit="fragment"` option to split tasks between workers by parquet fragment instead of row. When this is enabled, workers do not read every fragment while skipping 1 in n rows, but read all rows of 1/n fragments, which should be faster.
+- Accept no validation data in `edsnlp.train` script
+- Log the training config at the beginning of the trainings
+- Support a specific model output dir path for trainings (`output_model_dir`), and whether to save the model or not (`save_model`)
+- Specify whether to log the validation results or not (`logger=False`)
+- Added support for the CoNLL format with `edsnlp.data.read_conll` and with a specific `eds.conll_dict2doc` converter
+- Added a Trainable Biaffine Dependency Parser (`eds.biaffine_dep_parser`) component and metrics
+- New `eds.extractive_qa` component to perform extractive question answering using questions as prompts to tag entities instead of a list of predefined labels as in `eds.ner_crf`.
+
+### Fixed
+
+- Fix `join_thread` missing attribute in `SimpleQueue` when cleaning a multiprocessing executor
+- Support huggingface transformers that do not set `cls_token_id` and `sep_token_id` (we now also look for these tokens in the `special_tokens_map` and `vocab` mappings)
+- Fix changing scorers dict size issue when evaluating during training
+- Seed random states (instead of using `random.RandomState()`) when shuffling in data readers : this is important for
+  1. reproducibility
+  2. in multiprocessing mode, ensure that the same data is shuffled in the same way in all workers
+- Bubble BaseComponent instantiation errors correctly
+- Improved support for multi-gpu gradient accumulation (only sync the gradients at the end of the accumulation), now controled by the optiona `sub_batch_size` argument of `TrainingData`.
+- Support again edsnlp without pytorch installed
+- We now test that edsnlp works without pytorch installed
+- Fix units and scales, ie 1l = 1dm3, 1ml = 1cm3
+
+## v0.14.0 (2024-11-14)
+
+### Added
+
+- Support for setuptools based projects in `edsnlp.package` command
+- Pipelines can now be instantiated directly from a config file (instead of having to cast a dict containing their arguments) by putting the @core = "pipeline" or "load" field in the pipeline section)
+- `edsnlp.load` now correctly takes disable, enable and exclude parameters into account
+- Pipeline now has a basic repr showing is base langage (mostly useful to know its tokenizer) and its pipes
+- New `python -m edsnlp.evaluate` script to evaluate a model on a dataset
+- Sentence detection can now be configured to change the minimum number of newlines to consider a newline-triggered sentence, and disable capitalization checking.
+- New `eds.split` pipe to split a document into multiple documents based on a splitting pattern (useful for training)
+- Allow `converter` argument of `edsnlp.data.read/from_...` to be a list of converters instead of a single converter
+- New revamped and documented `edsnlp.train` script and API
+- Support YAML config files (supported only CFG/INI files before)
+- Most of EDS-NLP functions are now clickable in the documentation
+- ScheduledOptimizer now accepts schedules directly in place of parameters, and easy parameter selection:
+
+    ```
+    ScheduledOptimizer(
+        optim="adamw",
+        module=nlp,
+        total_steps=2000,
+        groups={
+            "^transformer": {
+                # lr will go from 0 to 5e-5 then to 0 for params matching "transformer"
+                "lr": {"@schedules": "linear", "warmup_rate": 0.1, "start_value": 0 "max_value": 5e-5,},
+            },
+            "": {
+                # lr will go from 3e-4 during 200 steps then to 0 for other params
+                "lr": {"@schedules": "linear", "warmup_rate": 0.1, "start_value": 3e-4 "max_value": 3e-4,},
+            },
+        },
+    )
+    ```
+
+### Changed
+
+- `eds.span_context_getter`'s parameter `context_sents` is no longer optional and must be explicitly set to 0 to disable sentence context
+- In multi-GPU setups, streams that contain torch components are now stripped of their parameter tensors when sent to CPU Workers since these workers only perform preprocessing and postprocessing and should therefore not need the model parameters.
+- The `batch_size` argument of `Pipeline` is deprecated and is not used anymore. Use the `batch_size` argument of `stream.map_pipeline` instead.
+
+### Fixed
+
+- Sort files before iterating over a standoff or json folder to ensure reproducibility
+- Sentence detection now correctly match capitalized letters + apostrophe
+- We now ensure that the workers pool is properly closed whatever happens (exception, garbage collection, data ending) in the `multiprocessing` backend. This prevents some executions from hanging indefinitely at the end of the processing.
+- Propagate torch sharing strategy to other workers in the `multiprocessing` backend. This is useful when the system is running out of file descriptors and `ulimit -n` is not an option. Torch sharing strategy can also be set via an environment variable `TORCH_SHARING_STRATEGY` (default is `file_descriptor`, [consider using `file_system` if you encounter issues](https://pytorch.org/docs/stable/multiprocessing.html#file-system-file-system)).
+
+### Data API changes
+
+- `LazyCollection` objects are now called `Stream` objects
+- By default, `multiprocessing` backend now preserves the order of the input data. To disable this and improve performance, use `deterministic=False` in the `set_processing` method
+- :rocket: Parallelized GPU inference throughput improvements !
+
+    - For simple {pre-process → model → post-process} pipelines, GPU inference can be up to 30% faster in non-deterministic mode (results can be out of order) and up to 20% faster in deterministic mode (results are in order)
+    - For multitask pipelines, GPU inference can be up to twice as fast (measured in a two-tasks BERT+NER+Qualif pipeline on T4 and A100 GPUs)
+
+- The `.map_batches`, `.map_pipeline` and `.map_gpu` methods now support a specific `batch_size` and batching function, instead of having a single batch size for all pipes
+- Readers now have a `loop` parameter to cycle over the data indefinitely (useful for training)
+- Readers now have a `shuffle` parameter to shuffle the data before iterating over it
+- In `multiprocessing` mode, file based readers now read the data in the workers (was an option before)
+- We now support two new special batch sizes
+
+    - "fragment" in the case of parquet datasets: rows of a full parquet file fragment per batch
+    - "dataset" which is mostly useful during training, for instance to shuffle the dataset at each epoch.
+  These are also compatible in batched writer such as parquet, where each input fragment can be processed and mapped to a single matching output fragment.
+
+- :boom: Breaking change: a `map` function returning a list or a generator won't be automatically flattened anymore. Use `flatten()` to flatten the output if needed. This shouldn't change the behavior for most users since most writers (to_pandas, to_polars, to_parquet, ...) still flatten the output
+- :boom: Breaking change: the `chunk_size` and `sort_chunks` are now deprecated : to sort data before applying a transformation, use `.map_batches(custom_sort_fn, batch_size=...)`
+
+### Training API changes
+
+- We now provide a training script `python -m edsnlp.train --config config.cfg` that should fit many use cases. Check out the docs !
+- In particular, we do not require pytorch's Dataloader for training and can rely solely on EDS-NLP stream/data API, which is better suited for large streamable datasets and dynamic preprocessing (ie different result each time we apply a noised preprocessing op on a sample).
+- Each trainable component can now provide a `stats` field in its `preprocess` output to log info about the sample (number of words, tokens, spans, ...):
+
+    - these stats are both used for batching (e.g., make batches of no more than "25000 tokens")
+    - for logging
+    - for computing correct loss means when accumulating gradients over multiple mini-mini-batches
+    - for computing correct loss means in multi-GPU setups, since these stats are synchronized and accumulated across GPUs
+
+- Support multi GPU training via hugginface `accelerate` and EDS-NLP `Stream` API consideration of env['WOLRD_SIZE'] and env['LOCAL_RANK'] environment variables
+
+## v0.13.1
+
+### Added
+
+- `eds.tables` accepts a minimum_table_size (default 2) argument to reduce pollution
+- `RuleBasedQualifier` now expose a `process` method that only returns qualified entities and token without actually tagging them, deferring this task to the `__call__` method.
+- Added new patterns for metastasis detection. Developed on CT-Scan reports.
+- Added citation of articles
+
+### Changed
+
+- Renamed `edsnlp.scorers` to `edsnlp.metrics` and removed the `_scorer` suffix from their
+  registry name (e.g, `@scorers = ner_overlap_scorer` → `@metrics = ner_overlap`)
+- Rename `eds.measurements` to `eds.quantities`
+- scikit-learn (used in `eds.endlines`) is no longer installed by default when installing `edsnlp[ml]`
+
+### Fixed
+
+- Disorder and Behavior pipes don't use a "PRESENT" or "ABSENT" `status` anymore. Instead, `status=None` by default,
+  and `ent._.negation` is set to True instead of setting `status` to "ABSENT". To this end, the *tobacco* and *alcohol*
+  now use the `NegationQualifier` internally.
+- Numbers are now only detected without trying to remove the pollution in between digits, ie `55 @ 77777` could be detected as a full number before, but not anymore.
+- Resolve encoding-related data reading issues by forcing utf-8
+
+## v0.13.0
+
+### Added
+
+- `data.set_processing(...)` now expose an `autocast` parameter to disable or tweak the automatic casting of the tensor
+  during the processing. Autocasting should result in a slight speedup, but may lead to numerical instability.
+- Use `torch.inference_mode` to disable view tracking and version counter bumps during inference.
+- Added a new NER pipeline for suicide attempt detection
+- Added date cues (regular expression matches that contributed to a date being detected) under the extension `ent._.date_cues`
+- Added tables processing in eds.measurement
+- Added 'all' as possible input in eds.measurement measurements config
+- Added new units in eds.measurement
+
+### Changed
+
+- Default to mixed precision inference
+
+### Fixed
+
+- `edsnlp.load("your/huggingface-model", install_dependencies=True)` now correctly resolves the python pip
+  (especially on Colab) to auto-install the model dependencies
+- We now better handle empty documents in the `eds.transformer`, `eds.text_cnn` and `eds.ner_crf` components
+- Support mixed precision in `eds.text_cnn` and `eds.ner_crf` components
+- Support pre-quantization (<4.30) transformers versions
+- Verify that all batches are non empty
+- Fix `span_context_getter` for `context_words` = 0, `context_sents` > 2 and support assymetric contexts
+- Don't split sentences on rare unicode symbols
+- Better detect abbreviations, like `E.coli`, now split as [`E.`, `coli`] and not [`E`, `.`, `coli`]
+
+## v0.12.3
+
+### Changed
+
+Packages:
+
+- Pip-installable models are now built with `hatch` instead of poetry, which allows us to expose `artifacts` (weights)
+  at the root of the sdist package (uploadable to HF) and move them inside the package upon installation to avoid conflicts.
+- Dependencies are no longer inferred with dill-magic (this didn't work well before anyway)
+- Option to perform substitutions in the model's README.md file (e.g., for the model's name, metrics, ...)
+- Huggingface models are now installed with pip *editable* installations, which is faster since it doesn't copy around the weights
+
+## v0.12.1
+
+### Added
+
+- Added binary distribution for linux aarch64 (Streamlit's environment)
+- Added new separator option in eds.table and new input check
+
+### Fixed
+
+- Make catalogue & entrypoints compatible with py37-py312
+- Check that a data has a doc before trying to use the document's `note_datetime`
+
+## v0.12.0
+
+### Added
+
+- The `eds.transformer` component now accepts `prompts` (passed to its `preprocess` method, see breaking change below) to add before each window of text to embed.
+- `LazyCollection.map` / `map_batches` now support generator functions as arguments.
+- Window stride can now be disabled (i.e., stride = window) during training in the `eds.transformer` component by `training_stride = False`
+- Added a new `eds.ner_overlap_scorer` to evaluate matches between two lists of entities, counting true when the dice overlap is above a given threshold
+- `edsnlp.load` now accepts EDS-NLP models from the huggingface hub 🤗 !
+- New `python -m edsnlp.package` command to package a model for the huggingface hub or pypi-like registries
+- Improve table detection in `eds.tables` and support new options in `table._.to_pd_table(...)`:
+  - `header=True` to use first row as header
+  - `index=True` to use first column as index
+  - `as_spans=True` to fill cells as document spans instead of strings
+
+### Changed
+
+- :boom: Major breaking change in trainable components, moving towards a more "task-centric" design:
+  - the `eds.transformer` component is no longer responsible for deciding which spans of text ("contexts") should be embedded. These contexts are now passed via the `preprocess` method, which now accepts more arguments than just the docs to process.
+  - similarly the `eds.span_pooler` is now longer responsible for deciding which spans to pool, and instead pools all spans passed to it in the `preprocess` method.
+
+  Consequently, the `eds.transformer` and `eds.span_pooler` no longer accept their `span_getter` argument, and the `eds.ner_crf`, `eds.span_classifier`, `eds.span_linker` and `eds.span_qualifier` components now accept a `context_getter` argument instead, as well as a `span_getter` argument for the latter two. This refactoring can be summarized as follows:
+
+    ```diff
+    - eds.transformer.span_getter
+    + eds.ner_crf.context_getter
+    + eds.span_classifier.context_getter
+    + eds.span_linker.context_getter
+
+    - eds.span_pooler.span_getter
+    + eds.span_qualifier.span_getter
+    + eds.span_linker.span_getter
+    ```
+
+    and as an example for the `eds.span_linker` component:
+
+    ```diff
+    nlp.add_pipe(
+        eds.span_linker(
+            metric="cosine",
+            probability_mode="sigmoid",
+    +       span_getter="ents",
+    +       # context_getter="ents",  -> by default, same as span_getter
+            embedding=eds.span_pooler(
+                hidden_size=128,
+    -           span_getter="ents",
+                embedding=eds.transformer(
+    -               span_getter="ents",
+                    model="prajjwal1/bert-tiny",
+                    window=128,
+                    stride=96,
+                ),
+            ),
+        ),
+        name="linker",
+    )
+    ```
+- Trainable embedding components now all use `foldedtensor` to return embeddings, instead of returning a tensor of floats and a mask tensor.
+- :boom: TorchComponent `__call__` no longer applies the end to end method, and instead calls the `forward` method directly, like all torch modules.
+- The trainable `eds.span_qualifier` component has been renamed to `eds.span_classifier` to reflect its general purpose (it doesn't only predict qualifiers, but any attribute of a span using its context or not).
+- `omop` converter now takes the `note_datetime` field into account by default when building a document
+- `span._.date.to_datetime()` and `span._.date.to_duration()` now automatically take the `note_datetime` into account
+- `nlp.vocab` is no longer serialized when saving a model, as it may contain sensitive information and can be recomputed during inference anyway
+
+### Fixed
+
+- `edsnlp.data.read_json` now correctly read the files from the directory passed as an argument, and not from the parent directory.
+- Overwrite spacy's Doc, Span and Token pickling utils to allow recursively storing Doc, Span and Token objects in the extension values (in particular, span._.date.doc)
+- Removed pendulum dependency, solving various pickling, multiprocessing and missing attributes errors
+
+## v0.11.2
+
+### Fixed
+- Fix `edsnlp.utils.file_system.normalize_fs_path` file system detection not working correctly
+- Improved performance of `edsnlp.data` methods over a filesystem (`fs` parameter)
+
+## v0.11.1 (2024-04-02)
+
+### Added
+
+- Automatic estimation of cpu count when using multiprocessing
+- `optim.initialize()` method to create optim state before the first backward pass
+
+### Changed
+
+- `nlp.post_init` will not tee lazy collections anymore (use `edsnlp.utils.collections.multi_tee` yourself if needed)
+
+### Fixed
+
+- Corrected inconsistencies in `eds.span_linker`
+
+## v0.11.0 (2024-03-29)
+
+### Added
+
+- Support for a `filesystem` parameter in every `edsnlp.data.read_*` and `edsnlp.data.write_*` functions
+- Pipes of a pipeline are now easily accessible with `nlp.pipes.xxx` instead of `nlp.get_pipe("xxx")`
+- Support builtin Span attributes in converters `span_attributes` parameter, e.g.
+  ```python
+  import edsnlp
+
+  nlp = ...
+  nlp.add_pipe("eds.sentences")
+
+  data = edsnlp.data.from_xxx(...)
+  data = data.map_pipeline(nlp)
+  data.to_pandas(converters={"ents": {"span_attributes": ["sent.text", "start", "end"]}})
+  ```
+- Support assigning Brat AnnotatorNotes as span attributes: `edsnlp.data.read_standoff(...,  notes_as_span_attribute="cui")`
+- Support for mapping full batches in `edsnlp.processing` pipelines with `map_batches` lazy collection method:
+  ```python
+  import edsnlp
+
+  data = edsnlp.data.from_xxx(...)
+  data = data.map_batches(lambda batch: do_something(batch))
+  data.to_pandas()
+  ```
+- New `data.map_gpu` method to map a deep learning operation on some data and take advantage of edsnlp multi-gpu inference capabilities
+- Added average precision computation in edsnlp span_classification scorer
+- You can now add pipes to your pipeline by instantiating them directly, which comes with many advantages, such as auto-completion, introspection and type checking !
+
+  ```python
+  import edsnlp, edsnlp.pipes as eds
+
+  nlp = edsnlp.blank("eds")
+  nlp.add_pipe(eds.sentences())
+  # instead of nlp.add_pipe("eds.sentences")
+  ```
+
+  *The previous way of adding pipes is still supported.*
+- New `eds.span_linker` deep-learning component to match entities with their concepts in a knowledge base, in synonym-similarity or concept-similarity mode.
+
+### Changed
+
+- `nlp.preprocess_many` now uses lazy collections to enable parallel processing
+- :warning: Breaking change. Improved and simplified `eds.span_qualifier`: we didn't support combination groups before, so this feature was scrapped for now. We now also support splitting values of a single qualifier between different span labels.
+- Optimized edsnlp.data batching, especially for large batch sizes (removed a quadratic loop)
+- :warning: Breaking change. By default, the name of components added to a pipeline is now the default name defined in their class `__init__` signature. For most components of EDS-NLP, this will change the name from "eds.xxx" to "xxx".
+
+### Fixed
+
+- Flatten list outputs (such as "ents" converter) when iterating: `nlp.map(data).to_iterable("ents")` is now a list of entities, and not a list of lists of entities
+- Allow span pooler to choose between multiple base embedding spans (as likely produced by `eds.transformer`) by sorting them by Dice overlap score.
+- EDS-NLP does not raise an error anymore when saving a model to an already existing, but empty directory
+
+## v0.10.7 (2024-03-12)
+
+### Added
+
+- Support empty writer converter by default in `edsnlp.data` readers / writers (do not convert by default)
+- Add support for polars data import / export
+- Allow kwargs in `eds.transformer` to pass to the transformer model
+
+### Changed
+
+- Saving pipelines now longer saves the `disabled` status of the pipes (i.e., all pipes are considered "enabled" when saved). This feature was not used and causing issues when saving a model wrapped in a `nlp.select_pipes` context.
+
+### Fixed
+
+- Allow missing `meta.json`, `tokenizer` and `vocab` paths when loading saved models
+- Save torch buffers when dumping machine learning models to disk (previous versions only saved the model parameters)
+- Fix automatic `batch_size` estimation in `eds.transformer` when `max_tokens_per_device` is set to `auto` and multiple GPUs are used
+- Fix JSONL file parsing
+
+## v0.10.6 (2024-02-24)
+
+### Added
+
+- Added `batch_by`, `split_into_batches_after`, `sort_chunks`, `chunk_size`, `disable_implicit_parallelism` parameters to processing (`simple` and `multiprocessing`) backends to improve performance
+  and memory usage. Sorting chunks can improve yield up to **twice the speed** in some cases.
+- The deep learning cache mechanism now supports multitask models with weight sharing in multiprocessing mode.
+- Added `max_tokens_per_device="auto"` parameter to `eds.transformer` to estimate memory usage and automatically split the input into chunks that fit into the GPU.
+
+### Changed
+
+- Improved speed and memory usage of the `eds.text_cnn` pipe by running the CNN on a non-padded version of its input: expect a speedup up to 1.3x in real-world use cases.
+- Deprecate the converters' (especially for BRAT/Standoff data) `bool_attributes`
+  parameter in favor of general `default_attributes`. This new mapping describes how to
+  set attributes on spans for which no attribute value was found in the input format.
+  This is especially useful for negation, or frequent attributes values (e.g. "negated"
+  is often False, "temporal" is often "present"), that annotators may not want to
+  annotate every time.
+- Default `eds.ner_crf` window is now set to 40 and stride set to 20, as it doesn't
+  affect throughput (compared to before, window set to 20) and improves accuracy.
+- New default `overlap_policy='merge'` option and parameter renaming in
+  `eds.span_context_getter` (which replaces `eds.span_sentence_getter`)
+
+### Fixed
+
+- Improved error handling in `multiprocessing` backend (e.g., no more deadlock)
+- Various improvements to the data processing related documentation pages
+- Begin of sentence / end of sentence transitions of the `eds.ner_crf` component are now
+  disabled when windows are used (e.g., neither `window=1` equivalent to softmax and
+  `window=0`equivalent to default full sequence Viterbi decoding)
+- `eds` tokenizer nows inherits from `spacy.Tokenizer` to avoid typing errors
+- Only match 'ne' negation pattern when not part of another word to avoid false positives cases like `u[ne] cure de 10 jours`
+- Disabled pipes are now correctly ignored in the `Pipeline.preprocess` method
+- Add "eventuel*" patterns to `eds.hyphothesis`
+
+## v0.10.5 (2024-01-29)
+
+### Fixed
+
+- Allow non-url paths when parquet filesystem is given
+
+## v0.10.4 (2024-01-19)
+
+### Changed
+
+- Assigning `doc._.note_datetime` will now automatically cast the value to a `pendulum.DateTime` object
+
+### Added
+
+- Support loading model from package name (e.g., `edsnlp.load("eds_pseudo_aphp")`)
+- Support filesystem parameter in `edsnlp.data.read_parquet` and `edsnlp.data.write_parquet`
+
+### Fixed
+
+- Support doc -> list converters with parquet files writer
+- Fixed some OOM errors when writing many outputs to parquet files
+- Both edsnlp & spacy factories are now listed when a factory lookup fails
+- Fixed some GPU OOM errors with the `eds.transformer` pipe when processing really long documents
+
+## v0.10.3 (2024-01-11)
+
+### Added
+
+- By default, `edsnlp.data.write_json` will infer if the data should be written as a single JSONL

+
+### Fixed
+
+- Measurements now correctly match "0.X", "0.XX", ... numbers
+- Typo in "celsius" measurement unit

+
+### Fixed
+
+- Microgram scale is now correctly 1/1000g and inverse meter now 1/100 inverse cm.
+- We now isolate some of edsnlp components (trainable pipes that require ml dependencies)
+  in a new `edsnlp_factories` entry points to prevent spacy from auto-importing them.
+- TNM scores followed by a space are now correctly detected
+- Removed various short TNM false positives (e.g., "PT" or "a T") and false negatives

+- The `eds.tokenizer` tokenizer has been added to entry points, making it accessible from the outside
+- Deprecate old connectors (e.g. BratDataConnector) in favor of the new `edsnlp.data` API
+- Deprecate old `pipe` wrapper in favor of the new processing API
+
+### Fixed
+
+- Support for pydantic v2
+- Support for python 3.11 (not ci-tested yet)
+
+## v0.10.0beta1 (2023-12-04)
+
+Large refacto of EDS-NLP to allow training models and performing inference using PyTorch
+as the deep-learning backend. Rather than a mere wrapper of Pytorch using spaCy, this is
+a new framework to build hybrid multi-task models.
+
+To achieve this, instead of patching spaCy's pipeline, a new pipeline was implemented in
+a similar fashion to aphp/edspdf#12. The new pipeline tries to preserve the existing API,
+especially for non-machine learning uses such as rule-based components. This means that
+users can continue to use the library in the same way as before, while also having the option to train models using PyTorch. We still
+use spaCy data structures such as Doc and Span to represent the texts and their annotations.
+
+Otherwise, changes should be transparent for users that still want to use spacy pipelines
+with `nlp = spacy.blank('eds')`. To benefit from the new features, users should use
+`nlp = edsnlp.blank('eds')` instead.
+
+### Added
+
+- New pipeline system available via `edsnlp.blank('eds')` (instead of `spacy.blank('eds')`)
+- Use the confit package to instantiate components
+- Training script with Pytorch only (`tests/training/`) and tutorial
+- New trainable embeddings: `eds.transformer`, `eds.text_cnn`, `eds.span_pooler`
+  embedding contextualizer pipes
+- Re-implemented the trainable NER component and trainable Span qualifier with the new
+  system under `eds.ner_crf` and `eds.span_classifier`
+- New efficient implementation for eds.transformer (to be used in place of
+  spacy-transformer)
+
+### Changed
+
+- Pipe registering: `Language.factory` -> `edsnlp.registry.factory.register` via confit
+- Lazy loading components from their entry point (had to patch spacy.Language.__init__)
+  to avoid having to wrap every import torch statement for pure rule-based use cases.
+  Hence, torch is not a required dependency
+
+## v0.9.2 (2023-12-04)
+
+### Changed

+
+### Added

+
+### Changes
+
+- Input and output of components are now specified by `span_getter` and `span_setter` arguments.
+- :boom: Score / disorders / behaviors entities now have a fixed label (passed as an argument), instead of being dynamically set from the component name. The following scores may have a different name
+  than the current one in your pipelines:
+    * `eds.emergency.gemsa` → `emergency_gemsa`
+    * `eds.emergency.ccmu` → `emergency_ccmu`
+    * `eds.emergency.priority` → `emergency_priority`
+    * `eds.charlson` → `charlson`
+    * `eds.elston_ellis` → `elston_ellis`
+    * `eds.SOFA` → `sofa`
+    * `eds.adicap` → `adicap`
+    * `eds.measuremets` → `size`, `weight`, ... instead of `eds.size`, `eds.weight`, ...
+- `eds.dates` now separate dates from durations. Each entity has its own label:
+    * `spans["dates"]` → entities labelled as `date` with a `span._.date` parsed object
+    * `spans["durations"]` → entities labelled as `duration` with a `span._.duration` parsed object
+- the "relative" / "absolute" / "duration" mode of the time entity is now stored in
+  the `mode` attribute of the `span._.date/duration`
+- the "from" / "until" period bound, if any, is now stored in the `span._.date.bound` attribute
+- `to_datetime` now only return absolute dates, converts relative dates into absolute if `doc._.note_datetime` is given, and None otherwise
+
+### Fixed

+## v0.4.1 (2022-03-14)
+
+- Added support to Koalas DataFrames in the `edsnlp.processing` pipe.
+- Added `eds.covid` NER pipeline for detecting COVID19 mentions.
+
+## v0.4.0 (2022-02-22)
+
+- Profound re-write of the normalisation :
+    - The custom attribute `CUSTOM_NORM` is completely abandoned in favour of a more _spacyfic_ alternative
+    - The `normalizer` pipeline modifies the `NORM` attribute in place
+    - Other pipelines can modify the `Token._.excluded` custom attribute
+- EDS regex and term matchers can ignore excluded tokens during matching, effectively adding a second dimension to normalisation (choice of the attribute and possibility to skip _pollution_ tokens
+  regardless of the attribute)
+- Matching can be performed on custom attributes more easily
+- Qualifiers are regrouped together within the `edsnlp.qualifiers` submodule, the inheritance from the `GenericMatcher` is dropped.
+- `edsnlp.utils.filter.filter_spans` now accepts a `label_to_remove` parameter. If set, only corresponding spans are removed, along with overlapping spans. Primary use-case: removing pseudo cues for
+  qualifiers.
+- Generalise the naming convention for extensions, which keep the same name as the pipeline that created them (eg `Span._.negation` for the `eds.negation` pipeline). The previous convention is kept
+  for now, but calling it issues a warning.
+- The `dates` pipeline underwent some light formatting to increase robustness and fix a few issues
+- A new `consultation_dates` pipeline was added, which looks for dates preceded by expressions specific to consultation dates
+- In rule-based processing, the `terms.py` submodule is replaced by `patterns.py` to reflect the possible presence of regular expressions
+- Refactoring of the architecture :
+    - pipelines are now regrouped by type (`core`, `ner`, `misc`, `qualifiers`)
+    - `matchers` submodule contains `RegexMatcher` and `PhraseMatcher` classes, which interact with the normalisation
+    - `multiprocessing` submodule contains `spark` and `local` multiprocessing tools
+    - `connectors` contains `Brat`, `OMOP` and `LabelTool` connectors
+    - `utils` contains various utilities
+- Add entry points to make pipeline usable directly, removing the need to import `edsnlp.components`.
+- Add a `eds` namespace for components: for instance, `negation` becomes `eds.negation`. Using the former pipeline name still works, but issues a deprecation warning.
+- Add 3 score pipelines related to emergency
+- Add a helper function to use a spaCy pipeline as a Spark UDF.
+- Fix alignment issues in RegexMatcher
+- Change the alignment procedure, dropping clumsy `numpy` dependency in favour of `bisect`
+- Change the name of `eds.antecedents` to `eds.history`.
+  Calling `eds.antecedents` still works, but issues a deprecation warning and support will be removed in a future version.
+- Add a `eds.covid` component, that identifies mentions of COVID
+- Change the demo, to include NER components
+
+## v0.3.2 (2021-11-24)
+
+- Major revamp of the normalisation.
+    - The `normalizer` pipeline **now adds atomic components** (`lowercase`, `accents`, `quotes`, `pollution` & `endlines`) to the processing pipeline, and compiles the results into a
+      new `Doc._.normalized` extension. The latter is itself a spaCy `Doc` object, wherein tokens are normalised and pollution tokens are removed altogether. Components that match on the `CUSTOM_NORM`
+      attribute process the `normalized` document, and matches are brought back to the original document using a token-wise mapping.
+    - Update the `RegexMatcher` to use the `CUSTOM_NORM` attribute
+    - Add an `EDSPhraseMatcher`, wrapping spaCy's `PhraseMatcher` to enable matching on `CUSTOM_NORM`.
+    - Update the `matcher` and `advanced` pipelines to enable matching on the `CUSTOM_NORM` attribute.
+- Add an OMOP connector, to help go back and forth between OMOP-formatted pandas dataframes and spaCy documents.
+- Add a `reason` pipeline, that extracts the reason for visit.
+- Add an `endlines` pipeline, that classifies newline characters between spaces and actual ends of line.
+- Add possibility to annotate within entities for qualifiers (`negation`, `hypothesis`, etc), ie if the cue is within the entity. Disabled by default.
+
+## v0.3.1 (2021-10-13)
+
+- Update `dates` to remove miscellaneous bugs.
+- Add `isort` pre-commit hook.
+- Improve performance for `negation`, `hypothesis`, `antecedents`, `family` and `rspeech` by using spaCy's `filter_spans` and our `consume_spans` methods.
+- Add proposition segmentation to `hypothesis` and `family`, enhancing results.
+
+## v0.3.0 (2021-09-29)
+
+- Renamed `generic` to `matcher`. This is a non-breaking change for the average user, adding the pipeline is still :
+
+  ```{ .python .no-check }
+  nlp.add_pipe("matcher", config=dict(terms=dict(maladie="maladie")))
+  ```
+
+- Removed `quickumls` pipeline. It was untested, unmaintained. Will be added back in a future release.
+- Add `score` pipeline, and `charlson`.
+- Add `advanced-regex` pipeline
+- Corrected bugs in the `negation` pipeline
+
+## v0.2.0 (2021-09-13)
+
+- Add `negation` pipeline
+- Add `family` pipeline
+- Add `hypothesis` pipeline
+- Add `antecedents` pipeline
+- Add `rspeech` pipeline
+- Refactor the library :
+    - Remove the `rules` folder
+    - Add a `pipelines` folder, containing one subdirectory per component
+    - Every component subdirectory contains a module defining the component, and a module defining a factory, plus any other utilities (eg `terms.py`)
+
+## v0.1.0 (2021-09-29)
+
+First working version. Available pipelines :
+
+- `section`
+- `sentences`
+- `normalization`
+- `pollution`
