Capistrano v3.0.0 Release Notes

  • If you are coming here to wonder why your Capfile doesn't work anymore, please ๐Ÿ”’ vendor lock your Capistrano at 2.x, whichever version was working for you until today.

    Capistrano 3 is a ground-up rewrite with modularity, stability, speed and future proofing in mind. It's a big change, but now the code is 10x smaller, โš™ runs faster, is easier to read, and quicker to extend. In the reduction we've ๐Ÿ”Œ come up with a great gem based modular system for plugins and we're really ๐Ÿš€ proud of this release.

    ๐Ÿš€ The 3.0.0 release contains 38 patches from the following amazing people:

    • Tom seenmyfate Clements: more than 28 patches including cucumber integration tests! Not to mention Rails asset pipeline code, and bundler integrations.
    • Lee Hambley: Small changes around compatibility and log formatting
    • Kir Shatrov: for improvements in the core to make it easier to write extensions, for improving documentation, and for effectively building the chruby, rvm and rbenv integrations.
    • Michael Nikitochkin: Fixing a bug around linked files and directories.
    • Jack Thorne: for improvements to the default Capfile to fix some bad example syntax.
    • Erik Hetzner: for (what looks like great) work on the Mercurial (Hg) support. The Hg and Git source control mechanisms do not work the same way, but rather lean on the strengths of the underlying tools.

      (If I missed anyone, I'm sorry, your contributions have been awesome)

    The 2.x branch of code is now no longer maintained. Towards the end of it's ๐Ÿ‘‰ useful life there were an increasing number of features and pieces of code which didn't make sense for certain groups of people, in certain situations, leading a to a ping-pong tennis effect with pull requests every few weeks ๐Ÿ›  "fixing" a use-case which had already been "fixed" shortly before. As many of โœ… the use-cases are outside the scope of the testing environments I (and by โœ… extension the trusted contributors and IRC regulars) were able to test for.

    There's a more extensive post about my failure to be able to keep up with the ๐Ÿ— demands of maintaining v2 whilst trying to build something which is appropriate ๐Ÿ‘ for the current landscape. If you are affected by the unsupported 2 branch, ๐Ÿ‘ please contact me (Lee Hambley) to discuss how my company can help support you. Otherwise, please try v3, we're sure you'll like it, and the code is designed to be so simple that anyone can work on it.
