This suggests that, as 1.8 superseded 1.6, 1.9 now supersedes 1.8, making it the current Ruby (though 1.8 remains for those who prefer to use it). Is that a reasonable interpretation? 1.8.8 is planned for release. Why, and when does 1.8 development stop? Put another way, for how long would people be expected that new code they write work on both 1.9 and 1.8? Or at what point would a developer tell users of 1.8 that backwards compatibility is no longer a priority? Yes, I known these are broad questions. I'm trying to get a sense of how the transition is intended and practiced. -- James Britt www.happycamperstudios.com - Wicked Cool Coding www.jamesbritt.com - Playing with Better Toys www.ruby-doc.org - Ruby Help & Documentation www.rubystuff.com - The Ruby Store for Ruby Stuff

Little fundamental changed, but a bunch of new useful classes like StringIO were added, and you could get them in 1.6 by adding the shim library. In part, that's what 1.8.7 gives you. But note that: - 1.9 has features which can't be back-ported to 1.8 (e.g. Fiber) - 1.9 runs a completely different engine under the hood, and bugs are still being turned up it. - 1.9 makes several important non-backwards-compatible changes, which break not only your own code but the code in libraries that you use. - some of us remain unconvinced about some of the new syntax, like the ugly -> lambda, and are still secretly hoping that they will be removed :-) Of these, I think the lack of library compatibility and the different engine may be the most important. Lots of people stayed on 1.6.8 for a long time not because of any major incompatibilities with 1.8, but because it was a stable and trusted platform.
