+- Update to 1.6.0:
+  * Changes
+    + Replaced the rANS codec SIMD gathers with simulated gathers
+      via scalar memory fetches. This helps AMD Zen4, but
+      importantly it also fixes a disastrous performance regression
+      caused by Intel's DownFall microcode fix.
+    + There is an impact on pre-DownFall speeds, but we should
+      focus on patched CPUs as a priority.
+    + A small speed up to the rans_F_to_s3 function used by
+      order-0 rans decode.
+    + Small speed up to SIMD rans32x16 order-1 encoder by reducing
+      cache misses. Also sped up the rans4x8 order-1 encoder,
+      particularly on AMD Zen4.
+    + Now supports building with "zig cc"
+  * Bug fixes
+    + Improve robustness of name tokeniser when given non 7-bit
+      ASCII and on machines where "char" defaults to unsigned.
+    + Also fixed a 1 byte buffer read-overrun in name tokeniser.
+    + Fix name tokeniser encoder failure with some duplicated
+      streams.
+    + Fixed rans_set_cpu to work multiple times, as well as
+      reinstating the ability to change decode and encode side
+      independently (accidentally lost in commit 958032c). No
+      effect on usage, but it improves the test coverage.
+    + Added a round-trip fuzz tester to test the ability to
+      encode. The old fuzz testing was decode streams only.
+    + Fixed bounds checking in rans_uncompress_O0_32x16_avx2,
+      fixing buffer read overruns.
+    + Removed undefined behaviour in transpose_and_copy(),
+      fixing zig cc builds.
