| 19:45 | Do not make the assumption (as check-in [4da49a95c0f07] incorrectly did) that the ExprList returned by sqlite3ExprListDup() would never be passed into sqlite3ExprListAppend(). Include a new test case that shows this sometimes does happen. (check-in: 29227d00a9 user: drh tags: trunk) | |

| 22:46 | Minor enhancement to the TclKit batch tool: it should download the TclKit EXE alone when the TCLKIT_NOENV environment variable is set. (check-in: baceb988c6 user: mistachkin tags: trunk) | |
| 19:34 | Small performance optimization in the freeSpace() routine of btree.c. (check-in: 63962e2a92 user: drh tags: trunk) | |

| 17:21 | Avoid passing (signed char) values directly to isspace(), isalnum() or isdigit() in json1.c. Cast the value to (unsigned char) first. (check-in: 6713e35b8a user: dan tags: trunk) | |
| 09:48 | Fix a crash in FTS5 caused by specifying NULL as the rhs of a MATCH operator. (check-in: e8ed62f82e user: dan tags: trunk) | |

| 23:37 | Performance improvement and slight size reduction to the comparison operators in the VDBE. (check-in: 14052a7d08 user: drh tags: micro-optimizations) | |
| 19:05 | Fix an unintialized variable problem in sqlite3ota.c. (check-in: 0126860751 user: dan tags: ota-update) | |
| 16:41 | In the Mem object, stop requiring that Mem.xDel be NULL when the MEM_Dyn bit is clear. Also reduce the amount of initialization of Mem objects. All for a small size reduction and performance increase. (check-in: fdddb477c8 user: drh tags: micro-optimizations) | |
| 15:20 | Add tests and fixes for "PRAGMA ota_mode". (check-in: 39df35c4ac user: dan tags: ota-update) | |
| 14:52 | Improved interface to the Mem object handling. Small size reduction and performance increase. (check-in: 4e43784432 user: drh tags: micro-optimizations) | |

| 20:06 | Speed improvements for in-memory databases by omitting flag clearing on pages where it is impossible for the flag to be set and by avoiding assert()s on non-debugging builds. Ticket #3384. (CVS 5715) (check-in: a7fd9e622b user: drh tags: trunk) | |
| 16:14 | Changes to test scripts to support running on symbian. (CVS 5714) (check-in: 6ef34e9d31 user: danielk1977 tags: trunk) | |
| 11:02 | Add a type identifier to argument sz to sqlite3PageMalloc() in pcache.c. Ticket #3383. (CVS 5713) (check-in: 94fde77b9a user: danielk1977 tags: trunk) | |
| 00:13 | Fix for tickets #3378 and #3381 that preserves the aliasing optimization. And yet, this fix feels uncomfortable. Seeking an alternative... (CVS 5712) (check-in: f8b759f197 user: drh tags: trunk) | |
