## V 0.3
*30 Jun 2022*
- C to V translation via C2V: `v translate file.c`. (Demo video: [Translating DOOM from C to V, building it in under a second and running it!](https://www.youtube.com/watch?v=6oXrz3oRoEg))
- Lots of bug fixes in V, cgen, and C interop to allow running translated DOOM.v.
- Programs built with the V compiler no longer leak memory by default.
- Closures. All operating systems are supported. ([Demo](https://twitter.com/v_language/status/1528710491882852352))

2022-06-30 10:41:09 +03:00
- `ustring` has been replaced with `[]rune` (works just like in Go).

- C backend is now parallel (just the cgen part for now).
- Lots of compiler source code clean up and minor optimizations. The compiler got ~30% faster according to fast.vlang.io.
- Better compiler source code organization (absolutely necessary as it's surpassed 100k loc).
- The naming of V's integer types is now more consistent: `byte` has been renamed to `u8`. Old code will continue working for 1 year and will result in a warning/hint.
- The typo detector now highlights the suggested name so that it's more visible.
- `datatypes` module now has `Heap, Queue, Stack, BSTree, LinkedList`.
- Interfaces can now be embedded (like structs).
- vlib now has a TOML parser, fully compatible with TOML 1.0.
- Lots of work done on the V.js backend, including the graphics library, which has been ported to V.js.
- JS promises, await (V.js).
- It's now possible to do more complex array initialization by using each individual element of the array (`[]int{init: it}`).
- Unsigned right shift operators `>>>` and `>>>=` have been added to V. (They work exactly like in Java.)
- `-nofloat` option, which is useful for writing kernels and for embedded systems without an FPU (used in Vinix).
- Generic interfaces.
- TCC is now bundled with the language, this allows building V programs without an external C compiler dependency.
- Null can be used in `unsafe` only (for example, for C interop).
- Pointer arithmetics and comparing pointers to numbers is now also only allowed in `unsafe`.
- Inline sumtypes.
- New module `compress.gzip`.
- Lots of `net`/`net.http`/`vweb` fixes (also used for the upcoming Gitly launch).
- IPv6 support.
- `net.http` headers are now enum fields instead of strings. This allows to avoid typos and offers autocomplete.
- Struct field deprecation.

- New various algorithms for random number generation: MT19937RNG, etc (module `rand`).
- Fix immutability bugs that allowed to bypass compiler immutability checks and modify const/immutable values.
- Lots of fixes in the JSON serializer.
2022-06-30 10:41:09 +03:00
- Heap allocated only structs marked with `[heap]`.

- Lots of new drawing functions in the graphics module (like `gg.draw_polygon_filled(), gg.draw_arc_empty()` etc)
- Builtin FPS display in `gg`.
- Latest Sokol backend in `gg`.
- Advanced CI tests for the graphics module. Graphical apps are run on GitHub Actions instances, their output is saved to an image, uploaded, and compared to the expected result.

- Bug fixes in aliases. They can now fully replace the types they alias.
2022-07-04 15:34:00 +03:00
- `[minify]` struct attribute for struct minification.
2022-06-30 10:41:09 +03:00
- `for in` now works with fixed arrays.
- The parser was made a bit faster by skipping `vfmt` code when not in `vfmt` mode (by using `-d vfmt`).
- Lots of vfmt improvements, especially with comments.
- Experimental `#[index]` syntax for negative indexing (like in Python, but needs special syntax instead of being used by default).
- Visibility bug fixes in modules (`pub`).
- Error propagation in complex expressions (e.g. `foo(bar()?)`).
- Optionals can now by used in consts (`const x := opt() or {}`).
- Lots of new documentation, including vlib modules documentation and the official V Documentation.

- `sync` improvements including `sync.thread_id()`, `sync.Once`..

- ORM fixes (pg, mysql, sqlite). Tables are now created automatically based on the V structs, no more need in sql files to create tables for apps.
- `volatile` keyword.
- `"stringliteral".len` optimization (replaced by the actual number by the new `transform` pass).
- Lots of inline assembler improvements (it's used a lot in Vinix).
- Many new functions in the `math` module.
- Separators in number literals: `1_000_000`.
- `strings.Builder` optimizations and new methods.
- Autofree fixes (still not production ready, hidden behind the `-autofree` flag).
