We're happy to announce the release of ruby-prof 0.7.0. Version 0.7.0 includes:

Features
--------
* Added two new methods - RubyProf.resume and RubyProf.pause.
RubyProf.resume takes an optional block, which ensures that
RubyProf.pause is called. For example:

10.times do |i|
RubyProf.resume do
# Some long process
end
end

result = RubyProf.stop

* Added support for profiling tests that use Ruby's built-in
unit test framework (ie, test derived from
Test::Unit::TestCase). To enable profiling simply add
the following line of code to your test class:

include RubyProf::Test

By default, profiling results are written to the current
processes working directory. To change this, or other
profiling options, simply modify the PROFILE_OPTIONS hash
table as needed.

* Used the new support for profiling test cases to revamp
the way that Rails profiling works. For more information
please refer to RubyProf's documentation.

* Keep track of call stack for each method to enable more
powerful profile visualizations in Integrated Development
Environments (Hin Boean, work supported by CodeGear).

* Expose measurements to Ruby (Jeremy Kemper).

* Add support for additional memory measurements modes in Ruby 1.9 (Jeremy Kemper).

* Add support for Lloyd Hilaiel's Ruby patch for measuring total heap size.
See http://lloydforge.org/projects/ruby. (Jeremy Kemper).


Fixes
-------
* RubyProf.profile no longer crashes if an exception is
thrown during a profiling run.

* Measure memory in fractional kilobytes rather than rounding down (Jeremy Kemper)
