An upgrade to Ruby is now available and it has an important bug fix for the year 2038 problem, IPv6 support and a new Random class.
Ruby 1.92 has been released and to quote from the Ruby blog:
Ruby 1.9.2 is mostly compatible with 1.9.1, except the following changes:
- Many new methods
- New socket API (enhanced IPv6 support)
- New encodings
- Random class that supports various random number generators
- Time is reimplemented. There is no longer the year 2038 problem.
- some regexp enhancements
- $: no longer includes the current directory.
- dl is reimplemented on top of libffi.
- new psych library that wraps libyaml. You can use the library instead of syck.
What you find important depends what you are doing but the fix to the 2038 problem has to be welcome and better Random number generators are always fun.
Compatibility seems to be good and where things are not backward compatible there is a good reason. There seems to be little point in not upgrading.
