Announcing ruby-prof 0.5.0 (fast profiler for ruby)

Hi everyone,

A quick note to say that Ruby Prof 0.5.0 has been released. If you
haven’t used it, ruby-prof is a fast profiler for Ruby. Version 0.5.0
is a major enhancement and has a lot of new functionality, including:

  • Support for profiling rails applications
  • Support for timing multi-threaded applications
  • Improved support for recursive methods
  • Support for measuring object allocations
  • New printer for call tree format used by KCachegrind

It also fixes a number of bugs, which can be seen in the change log.

Thanks to everyone who submitted bugs and patches - they are very much
