…p" and "remove" function now return Optionals. RingBuffer API rewritten. Allocator interface changed. Deprecated Allocator, DString and mem functions removed. "identity" functions are now constants for Matrix and Complex numbers. `@default` implementations for interfaces removed. `any*` => `any`, same for interfaces. Emit local/private globals as "private" in LLVM, following C "static". Updated enum syntax. Add support [rgba] properties in vectors. Improved checks of aliased "void". Subarray -> slice. Fix of llvm codegen enum check. Improved alignment handling. Add --output-dir c3lang#1155. Removed List/Object append. `GenericList` renamed `AnyList`. Remove unused "unwrap". Fixes to cond. Optimize output in dead branches. Better checking of operator methods. Disallow `any` from implementing dynamic methods. Check for operator mismatch. Remove unnecessary bitfield. Remove numbering in --list* commands Old style enum declaration for params/type, but now the type is optional. Add note on c3lang#1086. Allow making distinct types out of "void", "typeid", "anyfault" and faults. Remove system linker build options. "Try" expressions must be simple expressions. Add optimized build to Mac tests. Register int. `assert(false)` only allowed in unused branches or in tests. Compile time failed asserts is a compile time error. Remove current_block_is_target. Bug when assigning an optional from an optional. Remove unused emit_zstring. Simplify phi code. Remove unnecessary unreachable blocks and remove unnecessary current_block NULL assignments. Proper handling of '.' and Win32 '//server' paths. Add "no discard" to expression blocks with a return value. Detect "unsigned >= 0" as errors. Fix issue with distinct void as a member c3lang#1147. Improve callstack debug information c3lang#1184. Fix issue with absolute output-dir paths. Lambdas were not type checked thoroughly c3lang#1185. Fix compilation warning c3lang#1187. Request jump table using @jump for switches. Path normalization - fix possible null terminator out of bounds. Improved error messages on inlined macros.

Upgrade of mingw in CI. Fix problems using reflection on interface types c3lang#1203. Improved debug information on defer. $foreach doesn't create an implicit syntactic scope.
Error if `@if` depends on `@if`. Updated Linux stacktrace. Fix of default argument stacktrace. Allow linking libraries directly by file path. Improve inlining warning messages. Added `index_of_char_from`. Compiler crash using enum nameof from different module c3lang#1205. Removed unused fields in find_msvc. Use vswhere to find msvc. Update tests for LLVM 19
