Graphite 0.9.12 available

A new Graphite version has been released.
Just look at the number of bugfixes  and new features.

This is the last major update of 0.9.x branch.

Next major release will be 0.10.x, it will get megacarbon branch merged into trunk.

Another important feature I'd love to see in Graphite - it is carbon relay performance improvement.





0.9.12

8/22/2013

This is a patch release to fix a couple of critical regressions that made it into 0.9.11:

• Usage of django.utils.timezone breaks Django 1.3 compatibility
• Missing import in graphite.util breaks cache-queries
