Hi All,

I'm pleased to announce the release of MESA r11554.  This release fixes a
memory leak present in r11532 and is a recommended upgrade if you are using

The website will be updated momentarily.


Release notes:

Fix some memory leaks.  Several users saw long-running jobs killed due to
exhaustion of system memory.  Thanks to Avishai Gilkis for the report.

This release also sets the star_job control
num_steps_for_garbage_collection = 1000.  Periodically MESA will free some
memory from data structures that are no longer needed but have not been
deallocated yet.  At present, this only targets the EOS tables.
(Implemented by Rob Farmer)

The header of MESA history/profile files now includes information about the
compiler used and start date of the MESA run. (Implemented by Aaron Dotter)
