What's new in Nim 0.14.2
Aug 19, 2016
- Version 0.14.2 is just a bugfix release that fixes the most pressing regressions. In particular, the tar.xz now supports documentation generation, and the Windows installers bundle the latest stable nimble release.
New in Nim 0.14.0 (Aug 19, 2016)
- Library Additions
- The rlocks module has been added providing a reentrant lock synchronization primitive.
- A generic "sink operator" written as &= has been added to the
- system and the net modules. This operator is similar to the C++

New in Nim 0.12.0 (Aug 19, 2016)
- Library Additions
- The nre module has been added, providing a better interface to PCRE than re.
- The expandSymlink proc has been added to the os module.
- The tailDir proc has been added to the os module.
- Define nimPinToCpu to make the threadpool use explicit thread affinities. This can speed up or slow down the thread pool; it's up to you to benchmark it.
- strutils.formatFloat and formatBiggestFloat do not depend on the C locale anymore and now take an optional decimalSep = '.' parameter.
- Added unicode.lastRune, unicode.graphemeLen.
- Compiler Additions
- The compiler now supports a new configuration system based on NimScript.
- The compiler finally considers symbol binding rules in templates and generics for overloaded [], []=, {}, {}= operators (issue #2599).
- The compiler now supports a bitsize pragma for constructing bitfields.
- Added a new --reportConceptFailures switch for better debugging of concept related type mismatches. This can also be used to debug system.compiles failures.
- Language Additions
- system.unsafeAddr can be used to access the address of a let variable or parameter for C interoperability. Since technically this makes parameters and let variables mutable, it is considered even more unsafe than the ordinary addr builtin.
- Added macros.getImpl that can be used to access the implementation of a routine or a constant. This allows for example for user-defined inlining of function calls.
- Tuple unpacking finally works in a non-var/let context: (x, y) = f() is allowed. Note that this doesn't declare x and y variables, for this let (x, y) = f() still needs to be used.
- when nimvm can now be used for compiletime versions of some code sections. Click here for details.
- Usage of the type NimNode in a proc now implicitly annotates the proc with .compileTime. This means generics work much better for NimNode.

New in Nim 0.11.2 (Aug 19, 2016)
- This is just a bugfix release that fixes the most pressing regressions we introduced with version 0.11.0. The way types are computed was changed significantly causing all sort of problems. Sorry for the inconvenience; we grew overconfident our large test suite would prevent these things.
