+Announcing Python-Blosc2 3.8.0
 ==============================
 
-This is a maintenance release where:
+This is a minor version release where we have aimed to make the first steps
+towards complying fully with the array-api standard:
 
-✅ We have updated the Blosc2 C library to 2.21.1, which fixes a regression
-  in the build system detected in Fedora and Gentoo.
-✅ We reverted signature of ``TreeStore.__init__(()`` for making benchmarks
-  to get back to normal performance.
+✅ C-Blosc2 internal library updated to latest 2.21.2.
 
-Check our new blog post about ``TreeStore`` usage and performance at:
-https://www.blosc.org/posts/new-treestore-blosc2
+✅ numexpr version requirement pushed to 2.12.1 to incorporate
+``isnan``, ``isfinite``, ``isinf`` functions.
+
+✅ Indexing is now supported extensively and reasonably optimally for slices
+with negative steps, general boolean arrays and fancy indices, with both get/setitem having
+equal functionality. In PR #459 we extended the 1D fast path to general N-D,
+with consequent speedups. In PR #461 we allowed fancy indexing and general slicing
+with negative steps for set and getitem, with a memory-optimised path for setitem.
+
+✅ Various attributes and methods for the ``NDArray`` class, as well as functions, have
+been added to increase compliance with the array-api standard. In addition,
+linspace and arange functions have been made more numerically stable and now strictly
+comply even with difficult floating-point edge cases.
 
 You can think of Python-Blosc2 3.x as an extension of NumPy/numexpr that:
