| 00:58 | Add the "fossil git export" command, designed to simplify making a Git mirror of a working Fossil repository. (check-in: 70295942 user: drh tags: trunk) | |
| 00:26 | Enhance the "fossil git export" command so that it also exports tags as lightweight Git tags. (Closed-Leaf check-in: 4f19d67b user: drh tags: mirror-cmd) | |

| ||
| 21:36 | Do the export within a transaction for performance. Record a complete two-way map of Git and Fossil names in the mirror.mmark table. (check-in: c4f9b177 user: drh tags: mirror-cmd) | |
