This allows making V repos much cleaner. - `os.mkdir()` now has an optional `mode` parameter. - Full termux support via `$if termux {`. - Go backend fixes. - More type checks. - New keyword/type: `nil`. Only to be used inside `unsafe`. Replaces `voidptr(0)`. - DOOM is now translated/compiled and launched on CI servers. A screenshot of the running game is made via `vgret` and is compared to the expected result. - VLS performance improvements, especially on Windows. - Add `v ls` tool for installing, for updating, and for launching VLS (V Language Server) ## V 0.3 *30 Jun 2022* - C to V translation via C2V: `v translate file.c`.

As the result, building V got 26% faster. - Maps and arrays can now return optionals: `m[bad_key] or { ... }`, `if x := arr[key] { ... }`. - `ustring` has been replaced with `[]rune` (works just like in Go). - Maps can now have non-string keys. - A new compiler pass for transforming the AST (doesn't slow the compiler too much, adds about 25ms to `v self`). It eliminates unreachable branches and performs other simple optimizations and transformations. - 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`.
