+  library (@polytypic)
+- Changed the core Picos library to be internally built from a single `.ml` file
+  (@polytypic)

+  (@polytypic)
+- Added `lastly` as a safe alternative to `Fun.protect` (@polytypic)
+- Workarounds for the `Uri` library not being threadsafe (@polytypic)

 - Forbid cancelation propagation during `release` calls in the
   `picos_std.finally` library (@polytypic)
+  - This is a change in behaviour and could be seen as a breaking change, but it
+    should really be considered a bug fix.
 - Renamed `(Ivar|Stream).poison` to `(Ivar|Stream).poison_at` and added
   `(Ivar|Stream).poison` with optional `?callstack:int` (@polytypic)
