V 0.2 is out!

[medvednikov]

V 0.2 has been finally released!

This is the first major release. The main focus of this release has been on stability and compile-time memory management.

• Compile-time memory management via -autofree. Video demonstration.
  It will be enabled by default in 0.3
• Channels and locks.
• Thread safe typed arrays via keyword shared.
• Struct embedding.
• IO streams.
• A powerful websocket module that conforms to RFC 6455 and passes the Autobahn test suite (498 client tests and 249 server tests).
• The net module is now non blocking and is more feature complete providing similar API to Go.
• V's graphics module now uses Metal/DirectX/OpenGL instead of just OpenGL.
• V can now run in the browser via WASM and execute V code by translating it to JavaScript:
  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.
• A new tool v vet for analyzing the project and finding potential bugs and errors.
• A new term.ui module for building dynamic terminal UIs with an example editor written in it.
• Early iOS and Android support.
• All missing ORM features from the old backend were brought back.
• Magic it variable has been replaced with smart casts (the change is completely handled by vfmt).
• Cross-compiling to Windows and Linux brought back.
• C2V can now generate wrappers. Example: https://github.com/medvednikov/libsodium. (C2V will be released by 0.3)
• C++ compiler support: code, generated by the C backend can now by compiled by C++ compilers.
• Short generics syntax: foo(5) instead of foo<int>(5).
• Cached modules via -usecache. Faster compilation due to not needing to rebuild the entire vlib for
  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.
• modules.vlang.io is now generated automatically on every commit.
• Builtin compile-time JSON serializer now supports time.Time.
• Fixes in type aliases, to make them behave just like the types they alias.
• array.contains(element) is now generic.
• Lots of improvements in the JS backend and its type system.
• Simpler and more constinent function arg syntax: foo(a int, b int, c string) instead of foo(a, b int, c string)
• Lots of fixes and optimizations in the hashmap.
• Lots of missing checks in the type checker were added (for example, checking the correct usage of public struct fields).
• Mutability bug fixes
• Taking the address of a map value is no longer allowed, like in Go.
• Matrix multiplication.
• A new #pkgconfig flag to provide platform independent way to get compilation flags for C libraries/packages.
• Explicit parentheses requirement in complex boolean expressions.
• println was made even smarter, and can now handle complex types.
• Precompiled text templates can now be used outside of vweb via $tmpl().
• 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).
• unsafe fixes and improvements.
• Improvements to rand: rand.ulid(), rand.uuid(), a unified customizable PRNG API.
• Hundreds of other fixes, features, and tests (from now on the changelog will be updated
  right away as the feature/bug fix lands).
