   - `--allow-gnu-c` replaced by `-X __GNUC__`.
   - More flags changed or renamed.
 * The library loader does not implicitly search in the module's relative directory anymore. Add relevant libdirs explicitly.
-* All strings interfacing with the C extension have to be encoded as bytes. We do not do implicit UTF-8 encoding/decoding. (A new, opt-in string helper might be added in the future.)
+* All strings interfacing with the C extension have to be encoded as bytes. We do not support implicit UTF-8 encoding/decoding. (A new, opt-in string helper might be added in the future.)
 * We declare `c_void_p` as restype directly, which ctypes auto-converts to int/None. Previously, ctypesgen would use `POINTER(c_ubyte)` and cast to `c_void_p` via errcheck to bypass the auto-conversion. However, a `c_void_p` programatically is just that: an integer or null pointer, so the behavior of ctypes seems fine. Note that we can seamlessly `ctypes.cast()` an int to a pointer type. The API difference is that there is no `.value` property anymore. Instead, the object itself is the value, removing a layer of indirection.
 
 See also `--help` for usage details.
 
 ### New features and improvements (selection)
 
 * Implemented relative imports with `--link-modules`, and library handle sharing with `--no-embed-templates`. Removed incorrect `POINTER` override that breaks the type system.
-* Prevent assignment of invalid struct fields.
+* Prevent assignment of invalid struct fields by setting slots *in the class body*.
 * Slimmed up template by removing many avoidable wrappers.
-* Rewrote library loader. Resolve `.` to the module directory, not the caller's CWD. Don't add compile libdirs to runtime.
+* Rewrote library loader. Resolve `.` to the module directory, not the caller's CWD. Don't add compile libdirs to runtime. Handle iOS (PEP 730).
 * Better control over symbol inclusion via `--symbol-rules` (exposes `if_needed` strategy, allows free order of actions).
 * Symbol regex matching uses `fullmatch()` rather than `match()` (more explicit).
 * Eagerly include direct members with `--system-headers`. This helps lower the need for `--all-headers` (which generally includes a lot more than necessary).
 * Auto-detect default pre-processor.
 * Handle FAMs (Flexible Array members) as zero-sized arrays. See https://github.com/ctypesgen/ctypesgen/issues/219.
-* Changed the `UNCHECKED()` template to only remap non-primitive pointer types, and pass through anything else as-is. This avoids erroneously changing non-pointer types or `None` to `c_void_p`.
+* Tightened `UNCHECKED()` template to only remap pointer types, and pass through anything else as-is. This avoids erroneously changing non-pointer types or `None` to `c_void_p`.
 * `-X`: Ability to override arbitrary pre-processor default flags added by ctypesgen.
-* Pass through `-D/-U` in given order, i.e. honor undefines overriding defines, and vice versa.
+* Pass through `-D/-U` in given order.
