CONTRIBUTING.md

+Contributions to the library are gladly accepted.
+
+The main development happens in https://github.com/p12tic/libsimdpp repository.
+
+If you don't have time to submit a bug fix, please open an issue report on
+GitHub so at least the problem is known. The same applies to improvements -
+don't hesitate to open feature request so that the design of new APIs could
+take your use case into account.
+
+Documentation
+-------------
+
+The documentation is written on a MediaWiki instance which is currently private.
+If you find a problem in the documentation, please open an issue with a link to
+the page in question.
+
+Code changes
+------------
+
+Please test your code changes by running the following:
+
+```
+mkdir build
+cd build
+cmake ..
+
+# on Linux / macOS
+make check -j8
+
+# on Windows
+cmake --build . --target check
+```
+
+Please use the `dev` branch as a target for pull requests. The reason for this
+is that the public continuous integration services used by the library cover
+only SSE2-AVX2 instruction sets. The rest are periodically tested on a private
+test farm. Due to the number of tested compilers and library configurations
+this testing is usually done only on each merge from the `dev` branch to
+the `master` branch.
+
+Code style
+----------
+
+C-style pointer casts are discouraged, use reinterpret_cast for that. For
+non-pointer types C-style casts are preferred over static_cast or constructor.

ChangeLog

@@ -1,6 +1,34 @@
+What's new in v2.1:
+ * Various bug fixes
+ * Documentation has been significantly improved. The public API is now almost
+    fully documented.
+ * Added support for MIPS MSA instruction set.
+ * Added support for PowerPC VSX v2.06 and v2.07 instruction sets.
+ * Added support for x86 AVX512BW, AVX512DQ and AVX512VL instruction sets.
+ * Added support for 64-bit little-endian PowerPC.
+ * Added support for arbitrary width vectors in extract() and insert()
+ * Added support for arbitrary source vectors to to_int8(), to_uint8(),
+    to_int16(), to_uint16(), to_int32(), to_uint32(), to_int64(), to_uint64(),
+    to_float32(), to_float64().
+ * Added support for per-element integer shifts to shift_r() and shift_l().
+    Fallback paths are provided for SSE2-AVX instruction sets that lack
+    hardware per-element integer shift support.
+ * Make shuffle_bytes16(), shuffle_zbytes16(), permute_bytes16() and
+    permute_zbytes() more generic.
+ * New functions: popcnt, reduce_popcnt, for_each, to_mask()
+ * Xcode is now supported.
+ * The library has been refactored in such a way that older compilers are able
+    to optimize vector emulation code paths much better than before.
+ * Deprecation: implicit conversion operators to native vector types has been
+    deprecated and a replacement method has been provided instead. The implicit
+    conversion operators may lead to wrong code being accepted without a
+    compile error on Clang.
+
 What's new in v2.0:
 
  * Various bug fixes.
+ * Intel compiler is now supported on Windows. Newer versions of other compilers
+ are now supported.
