Read the 0.3.0 release blog for more details, and plans for 0.4.0.
Note You can try Wren on http://wren.io/try, and Wren CLI now has downloads.
0.3.0 is a fairly specific release, aimed at fixing build issues across platforms, streamlining the process for new users and making embedding easier. This is a stepping stone for working on language features and improving the VM, hacking on the docs and the VM is simpler than ever!
Builds now work out of the box on all primary platforms. Previously there was issues on Windows and other platforms due to unix-ey workflows being the default.
All the python scripts have also been fixed and updated (to python 3), and work consistently across all platforms out of the box too (including the tests, benchmarks, metrics etc). Like before, there was some things that didn't hold up on Windows or Mac. Fixed!
A lot of work has been done to also clarify the distinction between the CLI project and the VM, as well as move the CLI to it's own repo! This removes a lot of code that wasn't being used, and also been clarified the project structure.
Docs have also had a clean up, and a new page to try Wren directly on the doc page was added.
Read the 0.2.0 release blog for details, and plans for 0.3.0.
0.2.0 spans a pretty wide time period with around 290 commits. This includes many bug fixes, improvements, clarity in the code and documentation and so on. There are some minor API changes, be sure your header is up to date so the compiler can tell you what changed. There's too many changes to explicitly list, so below is the obvious user facing stuff that was easy to spot in the history.
Most noteworthy is that 'relative imports' are a slightly breaking change, but help pave the way forward toward a consistency for modules.
import was made smarter, differentiating relative from logicalFiber can now accept a value from the first call/transfer
String.trim, String.trimEnd, String.trimStart variantsString.split, String.replace, String.fromByte
String.indexOf(needle, startIndex)
Sequence.take and Sequence.skip
Num.pow, Num.log, Num.round
Num.largest, Num.smallest
List.filled(count, value)
Map iteration (MapEntry)wren.hpp for use in c++WrenVM
wrenAbortFiber
Please note that beyond 0.2.0 the CLI will have it's own changelog. This list is not exhaustive. For a fuller history see the commit log above.
