https://v-wasm.now.sh
|
||
- V binaries for Linux/Windows/macOS are now built and deployed automatically via GitHub Actions.
|
||
- Smart casting for sumtypes and interfaces, including complex expressions: `if x.expr is int { println(x.expr + 1) }`.
|
||
- Clean and easy way to sort arrays: `users.sort(a.name > b.name)`.
|
||
- A huge amount of `vfmt` fixes and improvements. It has now reached a point where it can be safely used on any V source file.
|
||
- A new CI job that runs `v fmt -verify` on the entire code base, a new command that makes sure the file/directory
|
||
has been vfmt'ed. This ensures that all code submitted to the V project is formatted.
|
||

|
||
each program. Will be enabled by default in 0.2.1.
|
||
- New improved sum types implementation.
|
||
- Lots of errors that happen often during the development cycle were turned into warnings to increase
|
||
development speed. They are still errors in production builds.
|
||
- Labeled `break` and `continue`.
|
||
- Lots of documentation. The official language documentation grew 3 times in size.

||
- Gitly, a big web application written in vweb has been released: https://github.com/vlang/gitly
|
||
- `['/:arg1/:arg2/action']` vweb action attribute for easily getting query parameters assigned to method arguments.
|
||
- Improved performance of text rendering, `gg.text_width()`.
|
||
- Webview module in V UI.
|
||
- Binary enum flags.
|
||
- `[export]` attribute to change exported function name (for example for calling from a C library).
|
||

|
||
can compile itself, all tests pass, and all examples compile.
|
||
- More tests have been uploaded.
|
||
- Cleaner bytes to string conversion: `tos2(bytes)` => `string(bytes)`.
