Coverage.py v3.2 beta 3 is available, with a fix for the debilitating memory leak introduced in 3.2 beta 1. If you tried using the latest coverage.py and found it consumed all your RAM, this one will work much better.

Other changes since beta 1:

• Branch coverage has been improved. A few Python constructs were marked as branches because of their structure in bytecode, but shouldn’t have been because conceptually there is no branch. Also, excluded source lines no longer count as branch targets.
• The --omit command-line flag works much better.
• The HTML report now has click-to-sort columns, thanks to Chris Adams.
