+Announcing Python-Blosc2 3.3.3
 ==============================
 
-This is a bugfix release, with some minor optimizations.  We fixed
-specially a bug in the determination of chunk shape in constructors
-on CPUs with large L3 cache sizes (like AMD EPYC).  We also fixed a
-bug preventing the correct chaining of *string* lazy expressions for
-logical operators (``&``, ``|``, ``^``...).
+This is a bugfix release, with some minor optimizations. We improved the
+correct chaining of *string* lazy expressions (there is still room for
+improvement).  Also, a new version of C-Blosc2 (v2.7.2.dev) that fixes
+mmap issues on Windows is used; thanks to @JanSellner for the fix.
 
 You can think of Python-Blosc2 3.x as an extension of NumPy/numexpr that:

 ## Changes from 3.3.2 to 3.3.3
 
-XXX version-specific blurb XXX
+* Expand possibilities for chaining string-based lazy expressions to include
+  main operand types (LazyExpr and NDArray). Still have to incorporate other
+  data types (which do not have shape attribute, e.g. int, float etc.).
+  See #406.
+
+* Fix indexing for lazy expressions, and allow use of None in getitem.
+  See PR #402.
+
+* Fix incorrect appending of dim to computed reductions. See PR #404.
+
+* Fix `blosc2.linspace()` for incompatible num/shape.  See PR #408.
+
+* Add support for NumPy dtypes that are n-dimensional (e.g.
+  `np.dtype(("<i4,>f4", (10,))),`).
+
+* New MAX_DIM constant for the maximum number of dimensions supported.
+  This is useful for checking if a given array is too large to be handled.
+
+* More refinements on guessing cache sizes for Linux.
+
+* Update to C-Blosc2 2.17.2.dev.  Now, we are forcing the flush of modified
+  pages only in write mode for mmap files. This fixes mmap issues on Windows.
+  Thanks to @JanSellner for the implementation.
