| Bugs reported after the release of 3.8.0 |
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
| |
| This file lists bugs that were reported after 3.8.0 was released, both |
| in 3.8.0 and trunk, and that have not been closed. Bugs that have |
| been closed as "fixed" are listed in the top level NEWS file instead. |
| In other words they get listed here first and moved to NEWS if they |
| get fixed. |
| |
| This file also tracks commits & fixes that should be pushed to the 3.8 |
| branch. |
