A few words about the bug tracker

Some know the last two weeks the bug tracker lay. Yesterday his work was restored with the following restrictions:
- Existing bugs (before the fall) will be read only
- Attached patches are not available.
- Only new bugs can be edited / modified.

The main thing is that now the bug tracker is available only at https : //bugs.php.net

Work on the full restoration is underway. Premature launch is due to the release of PHP 5.4 alpha1. A little more you can read here .

UPD. The bug tracker is fully restored.
