@@ -25,6 +25,18 @@ Fixes:
  - Fixed `mdbx_check_fs_local()` for CDROM case on Windows.
  - Fixed nasty typo of typename which caused false `MDBX_CORRUPTED` error in a rare execution path,
    when the size of the thread-ID type not equal to 8.
+ - Fixed write-after-free memory corruption on latest `macOS` during finalization/cleanup of thread(s) that executed read transaction(s).
+   > The issue was suddenly discovered by a [CI](https://en.wikipedia.org/wiki/Continuous_integration)
+   > after adding an iteration with macOS 11 "Big Sur", and then reproduced on recent release of macOS 12 "Monterey".
+   > The issue was never noticed nor reported on macOS 10 "Catalina" nor others.
+   > Analysis shown that the problem caused by a change in the behavior of the system library (internals of dyld and pthread)
+   > during thread finalization/cleanup: now a memory allocated for a `__thread` variable(s) is released
+   > before execution of the registered Thread-Local-Storage destructor(s),
+   > thus a TLS-destructor will write-after-free just by legitime dereference any `__thread` variable.
+   > This is unexpected crazy-like behavior since the order of resources releasing/destroying
+   > is not the reverse of ones acquiring/construction order. Nonetheless such surprise
+   > is now workarounded by using atomic compare-and-swap operations on a 64-bit signatures/cookies.
+ - Fixed Elbrus/E2K LCC 1.26 compiler warnings (memory model for atomic operations, etc).
