We're happy to announce the release of ruby-prof 0.6.0. Version 0.6.0 adds support for Ruby 1.9 and memory profiling. It also fixes a number of bugs as detailed below.

Features
--------
* Added support for ruby 1.9 (Shugo Maeda)

object (Michael Granger)
* Add new memory profiling mode. Note this mode depends on a
patched Ruby interpreter (Alexander Dymo)

Fixes
-------
* Improvements to GraphHtmlPrinter including updated documentation,
fixes for min_time support, ability to specify templates using
strings or filenames, and table layout fixes (Makoto Kuwata)
* Fixes to scaling factor for calltrees so that precision is not lost
due to the conversion to doubles (Sylvain Joyeux)
* Changed constant ALLOCATED_OBJECTS to ALLOCATIONS in the C code to
match the Ruby code (Sylvain Joyeux)
* Added support for calltree printer to ruby-prof binary script (Sylvain Joyeux)
* Fix support for the allocator measure mode to extconf.rb (Sylvain Joyeux)
* Honor measure mode when specified on the command line (Sylvain Joyeux)
* Sorting of methods by total time was incorrect (Dan Fitch, Charlie Savage)
* Fix ruby-prof to work with the latest version of GEMS (Alexander Dymo)
* Always define MEASURE_CPU_TIME and MEASURE_ALLOCATIONS in Ruby code, but
set their values to nil if the functionality is not available.
