+## Change stack_depth_t to size_t on OpenBSD
+
+The definition of stack_depth_t was changed from int to size_t to support compiling on OpenBSD 7.6.
+
+ponyc may not be compilable on earlier versions of OpenBSD.
+
+## Make sure scheduler threads don't ACK the quiescence protocol CNF messages if they have an actor waiting to be run
+
+Prior to this, the pinned actor thread could cause early termination/quiescence of a pony program if there were only pinned actors active. This change fixes the issue to ensure that pony programs with only pinned actors active will no longer terminate too early.
+
+## Apply default options for a CLI parent command when a sub command is parsed
+
+In the CLI package's parser, a default option for a parent command was ignored when a subcommand was present. This fix makes sure that parents' defaults are applied before handling the sub command.
+
+## Fix compiler crash from `match` with extra parens around `let` in tuple
+
+When matching on a tuple element within a union type, the compiler would crash when extra parentheses were present.
+
+The following code fails to compile because of `(123, (let x: I32))` in the `match`. The extra parentheses should be ignored and treated like `(123, let x: I32)`.
+
+```pony
+let value: (I32 | (I32, I32)) = (123, 42)
+
+match value
+| (123, (let x: I32)) => x
+end
+```
+
+## Fix soundness problem when matching `iso` variables
+
+We previously switched our underlying type system model. In the process, a
+soundness hole was introduced. The following code that should not compile was accepted by the compiler:
+
+```pony
+class Bad
+  let _s: String iso
+
+  new iso create(s: String iso) =>
+    _s = consume s
+
+  fun ref take(): String iso^ =>
+    match _s
+    | let s': String iso => consume s'
+    end
+```
+
+The code should not compile because `let s': String iso` is aliasing `_s` an iso field. Consuming an aliased iso shouldn't return an iso^.
+
+The take-away is that "very bad things could happen" and the data race freedom guarantees of the Pony compiler were being violated.
+
+We've closed the soundness hole. We recommend all Pony users update to the this release as soon as possible.
