Version 0.14.2 released

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.


Version 0.14.0 released

It’s been a while since the last release, but we’ve been very busy in the meantime. In addition to working on Nim we have started a BountySource campaign and announced the pre-release of a new Nim book titled Nim in Action. Our BountySource campaign has already been very successful, helping us raise enough funds to surpass 4 of our monthly goals. The companies and individuals that made this possible are listed on our brand new sponsors page.


Meet our BountySource sponsors

It has now been two months since we began our fundraiser. Time to meet our current sponsors.

Version 0.11.2 released

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.


Version 0.11.0 released

With this release we are one step closer to reaching version 1.0 and by extension the persistence of the Nim specification. As mentioned in the previous release notes, starting with version 1.0, we will not be introducing any more breaking changes to Nim.


Version 0.10.2 released

This release marks the completion of a very important change to the project: the official renaming from Nimrod to Nim. Version 0.10.2 contains many language changes, some of which may break your existing code. For your convenience, we added a new tool called nimfix that will help you convert your existing projects so that it works with the latest version of the compiler.


New website design!

A brand new website including an improved forum is now live. All thanks go to Philip Witte and Dominik Picheta, Philip Witte for the design of the website (together with the logo) as well as the HTML and CSS code for his template, and Dominik Picheta for integrating Philip’s design with Nim’s forum. We’re sure you will agree that Philip’s design is beautiful.


Version 0.9.6 released

Note: 0.9.6 is the last release of Nimrod. The language is being renamed to Nim. Nim slightly breaks compatibility.


Version 0.9.4 released

The Nimrod development community is proud to announce the release of version 0.9.4 of the Nimrod compiler and tools. Note: This release has to be considered beta quality! Lots of new features have been implemented but unfortunately some do not fulfill our quality standards yet.
