- `map.delete(key)`. 
- `libcurl` dependency was removed from the `http` module.

  modifed inside the function).

- `vweb` static files serving. 
- `crypto.rand` module. 
- `v up` to update V.

- All arrays now have a default `.str()` method. 
- Bootstrapping V with MSVC. 
- Experimental `≠` etc support.
- `encoding.csv` module. 
- `$if debug {` for running code in debug mode only. 
- Map struct fields are now initialized automatically, just like arrays. 
- Maps now support array values. 
- `json` functions can no longer be used if the `json` module is not imported. 
 


## V 0.1.17 
*29 Jul 2019* 
- `vweb` module for developing web apps in V. 
- vtalk, open source V forum software. 
- Generics (very limited right now, but they will be gradually improved).  
- Comptime codegen (`foo.$method()` where `method` is a string). 
- @ for escaping keywords (e.g. `struct Foo { @type string }`). 
- Windows Unicode fixes (V can now work with non-ASCII paths etc on Windows). 
- Fix mutable args bugs + don't allow primitive arguments to be modified.  
- Declaring a mutable variable and never modifying it results in a compilation error.
- Interactive debugging support.
- `sync` module for Windows.
- `#!` support on Unix systems (V scripts).
- Lots of Visual Studio fixes.

- Internal modules.





## V 0.1.16 
*23 Jul 2019* 
- V can now be used with Visual Studio! 
- Hot code reloading now works with graphical applications (e.g. graph.v, bounce.v).  
- Compile time memory management for arrays. 
- High order functions. 
- `match` expression (replacing `switch`).

- `crypto/md5`, `crypto/sha256`, and `crypro/sha512` modules.
- `os.executable()` - a cross platform function that returns full path to current executable. 
- `~/.vlang` and `VROOT` were removed entirely. The installation is a lot cleaner now. 
- V can now be packaged for all Linux distros. 
- Arch Linux package. 
- `string(bytes_buffer, len)`, `string(bytes_array)` casts. 
- Multiple `defer`s. 
- `key in map` syntax (replacing `map.exists(key)`). 



## V 0.1.15 
*15 Jul 2019* 
- FreeBSD, OpenBSD, NetBSD, DragonFly support. 
- Hot code reloading now works with graphical applications: [bounce.v](https://github.com/vlang/v/blob/master/examples/hot_code_reloading/bounce.v)

- `flag` module for parsing command line arguments. 
- `zip` module.

- Submodules and module aliases (`import encoding.base64 as b64`). 




## V 0.1.14 
*12 Jul 2019* 
- `gg` module Windows support, V Tetris runs on Windows. 
- `glad` and `cJSON` are now compiled only once, this makes compilation of programs using `gg` and `json
  a bit faster. 
- `v.c` has been cleaned up and minimized (~16k => ~10k lines of code). 
- `type` aliases can now have methods.  
- Const overflow check during compilation (`byte(1000)` will no longer compile) 


## V 0.1.13
*10 Jul 2019* 
- New enum syntax (`token == .name`), enum values are no longer global consts.
- Submodules (`import encoding.base64`).
- Hot code reloading.
- Special `err` variable for getting error values.
- Complex numbers.
- `<<` can now append arrays (`numbers << [1, 2, 3]`).
- Lots of Windows fixes (Windows still needs some work).

- The website was made easily translatable, it's now partially available in several languages.


## V 0.1.12
*4 Jul 2019* 
- V can finally compile itself on Windows. (https://github.com/vlang/v#mingw-w64)
- `os` module now uses optionals in all functions that return `File`. Lots of  bugs with optionals fixed.

- File structure has been simplified: all vlib modules were moved to the vlib/ directory,
  makefile was moved to the root.
- One single archive with pre-built binaries for all operating systems.

## 0.1.8
*28 Jun 2019*

  can compile itself, all tests pass, and all examples compile.
- More tests have been uploaded.
- Cleaner bytes to string conversion: `tos2(bytes)` => `string(bytes)`.
- The home page has 3 more examples next to 'hello world' that show the features of the language.
- Lots of bugs and issues fixed.
