2016-01-XX Version 0.13.0 released
|
||||
==================================
|
||||
|
||||
Once again we are proud to announce the latest release of the Nim compiler
|
||||
and related tools. This release comes just 3 months after the last
|
||||
release!
|
||||
|
||||
A new version of Nimble which depends on this release, has also been
|
||||
released. See `this <http://forum.nim-lang.org/t/1912>`_ forum thread for
|
||||
more information about the Nimble release.
|
||||
|
||||
This release of Nim includes over 116 bug fixes, many of which are related
|
||||
to closures. The lambda lifting algorithm in the compiler has been completely
|
||||
rewritten, and some changes have been made to the semantics of closures in
|
||||
Nim as a result. These changes may affect backwards compatibility and are all
|
||||
described in the section below.
|
||||
|
||||
With this release, we are one step closer to Nim version 1.0.
|
||||
The 1.0 release will be a big milestone for Nim, because after that version
|
||||
is released there will be no more breaking changes made to the language
|
||||
or the standard library.
|
||||
|
||||
That being said, the next release will likely be Nim 0.14. It will focus on
|
||||
improvements to the GC and concurrency. We will in particular be looking at
|
||||
ways to add multi-core support to async await. Standard library improvements
|
||||
are also on our roadmap but may not make it for Nim 0.14.
|
||||
|
||||
As always you can download the latest version of Nim from the
|
||||
`download <download.html>`_ page.
|
||||
|
||||
Happy coding!
