+
+#### Improvements in the language
+- Short lambda expressions like `a.sorted(|x,y| x > y)` (#19390)
+- Support `-os plan9`, `$if plan9 {`, and `_plan9.c.v` (stage 1 for plan9) (#19389)
+- fmt: simplify the processing logic for removing inline comments (#19297)
+- Align the custom values of the enum fields (#19331)
+- Do not warn/error for `import flag as _`
+- Keep anon struct decl fields in interfaces (#19461)
+- Support -N, turning all notices into errors, to ease the process of finding places that may need attention/correction
+
+#### Breaking changes
+- Remove inline comments (#19263)
+
+#### Checker improvements/fixes
+- Disallow module name duplicates in local names (#18118)
+- Check enum fields with duplicate value (fix #19309) (#19310)
+- Disallow alias ptr cast of a map value (#19336)
+- Require `else` branch in `[flag]` enum match (#19375)
+- Disallow assigning pointer values to option struct fields (#19380)
+- Fix generic comparison for conditional assignment (#19401)
+- Allow using ! and ~ on aliased bool and integral types (#19403)
+- Warn -> error for uninitialized ref fields
+- Parser, checker: allow lambdas anywhere anonymous functions are expected (#19436)
+- Allow for `each(a, |x| println(x))`, i.e. using lambda expressions, when expecting `fn (x int)`
+- Check fixed array init with default expression (#19472)
+- Allow for `const source = $embed_file(@FILE).to_string()`
+- Fix C.type in imported modules
+
+#### Parser improvements
+- parser: fix fixed array with eval const size (#19269)
+- parser: disallow using `sql` as name (#19298)
+- parser: fix `;` support for `module x;`
+- parser: fix fixed array of option values (`_ := [10]?int{}`) (#19392)
+- parser: fix assigning with in another module sumtypes 2 (#19415)
+- v.ast: improve Stmt.str(), showing more details about ast.Block, ast.DeferStmt, ast.ForInStmt, ast.GlobalDecl
+
+#### Compiler internals
+- pref: support `-fast-math`, passing either -ffast-math or /fp:fast (for msvc) to the C backend, and `$if fast_math {` to detect it at comptime
+- parser, transformer: fix transformer.infix_expr() and cleanup parse_types.v (related #19269) (#19276)
+- pref,builder: support -use-os-system-to-run to workaround segfaults using not fully updated xcode command line tools
+- v.builder: fix compiling code, that imports modules from both `src/modules` and `modules` (#19437)
+- os, v.builder: show more details, when a program ran by `v run file.v`, exits by a signal (fix #19412) (#19471)
+
+#### Standard library
+- math: speedup the pure V math.pow implementation for non-fractional powers (#19270)
+- math: add more C. fn overrides, for the default C backend (speed up examples/path_tracing.v) (#19271)
+- time: add `MMM` support for parse_format() (#19284)
+- os: include sys/sysctl.h on FreeBSD to avoid implicit definition of sysctl function (#19293)
+- crypto.md5: change the Digest.write return type, from `?int` to `!int` (#19311)
+- v.help: use os.executable() instead of @VEXE as an anchor, so `v help` will work more robustly.
+- toml: fix custom `to_toml` for complex structs (#19338)
+- all: support `;` statements, allowing for oneliners like `./v -e 'import os; println( os.ls(os.args[1])!.sorted(a > b) )' vlib/math` (#19345)
+- vlib: add net.http.file, allowing for `v -e "import net.http.file; file.serve()"` (#19348)
+- vlib: remove functions and fields, deprecated before 2023-03-20

+- arrays: add arrays.each, arrays.each_indexed, and tests for them
+- encoding.html: implement `unescape()` (#19267)
+
+#### Web
+- net.http: fix http.fetch(), without explicit method (default again to .get, not to .acl)

+
+#### Native backend
+- native: make native tests pass on windows; refactor PE file generation (#19140)
