Upgrade now!

Thu 27 March 2008

In case you haven't heard through some other channel already, Twisted 8 is out.

In addition to numerous fixes and features, this release also includes a new release system for Twisted itself; this (hopefully) means that we won't have another year-long release drought.  We're planning to do another release in less than 3 months.

This means that new Twisted features will be available faster, but it also means that if you're writing some software that uses Twisted, upgrade now!  We try very hard to make sure that each new release is mostly compatible with the one that comes before it, so that your upgrade should be painless.  Especially if you have good unit tests.

However, this compatibility doesn't extend infinitely.  There are at least a few twisted developers who would really like to drop some of our years of accumulated cruft and break compatibility with older versions.

If you upgrade now, your migration process will be gradually fixing a few deprecation warnings.  If you wait for 3 or 4 more minor releases, upgrading all at once will mean that anything which has changed will start off broken, and your tests might not even run until you've fixed a bunch of things.

Of course, by "will", I mean "should" - we're not perfect, but we'll fix upgrade issues in micro releases if you find them and report them.
