* Multithreading checks only apply to Python defined codecs and filters.
Now it is possible to use multithreading with C codecs and filters plugins.
See PR 127.

* New support for dynamic filters registry for Python.

* Now params for codec and filter plugins are correctly initialized
when using `register_codec` and `register_filter` functions.

* Some fixes for Cython 3.0.0. However,compatibility with Cython 3.0.0
is not here yet, so build and install scripts are still requiring Cython<3.

* Updated to latest C-Blosc2 2.10.1.

* Updated to latest C-Blosc2 2.10.0.

* Use the new, fixed bytedelta filter introduced in C-Blosc2 2.10.0.

* Some small fixes in tutorials.

* Added a new [section of tutorials](https://www.blosc.org/python-blosc2/getting_started/tutorials.html) for a quick get start.

* Added a new [section on how to cite Blosc](https://github.com/Blosc/python-blosc2/tree/main#citing-blosc).

* New method `interchunks_info` for `SChunk` and `NDArray` classes.
This iterates through chunks for getting meta info, like decompression ratio, whether the chunk is special or not, among others. For more information on how this works see [this example](https://github.com/Blosc/python-blosc2/blob/main/examples/ndarray/iterchunks_info.py).

* Now it is possible to register a dynamic plugin by passing `None` as the `encoder` and `decoder` arguments in the [register_codec](https://www.blosc.org/python-blosc2/reference/autofiles/top_level/blosc2.register_codec.html#blosc2.register_codec) function.

* Make shape of scalar slices NDArray objects to follow NumPy conventions. See [117](https://github.com/Blosc/python-blosc2/issues/117).

* Updated to latest C-Blosc2 2.9.3.

* Wheels are not including blosc2.pc (pkgconfig) anymore. For details see:
https://github.com/Blosc/python-blosc2/pull/111 . Thanks to bnavigator for the PR.

* Updated to latest C-Blosc2 2.9.1.
