| 20:43 | Minor code simplification. (check-in: 22ae8a52 user: drh tags: trunk) | |
| 20:15 | Add the "PRAGMA legacy_alter_table=ON" command to enable the pre-3.25.0 behavior of ALTER TABLE that does not modify the bodies of triggers or views or the WHERE clause of a partial index. Enable the legacy behavior by default when running the xRename method of virtual tables. (check-in: 7edd26ed user: drh tags: trunk) | |
| 19:02 | Combine the Expr.pTab and Expr.pWin fields into a union named "y". Add a new EP_WinFunc property that is only true if Expr.y.pWin is a valid pointer. This reduces the size of the Expr object by 8 bytes, reduces the overall amount of code, and shaves over 1 million cycles off of the speed test. (check-in: ad130bb8 user: drh tags: trunk) | |
| 17:21 | By default, make all "ALTER TABLE RENAME" statements executed within a virtual table xRename() method exhibit the legacy behaviour. (Closed-Leaf check-in: 71947337 user: dan tags: legacy-alter-table) | |
| 08:28 | Add a PRAGMA that restores the legacy ALTER TABLE RENAME TO behaviour. (check-in: 5acad2e9 user: dan tags: legacy-alter-table) | |

| 18:47 | Size and performance optimization on sqlite3VdbeMemGrow(). (check-in: 4b3f7eac user: drh tags: trunk) | |
| 18:07 | The BLOB returned by sqlite3VdbeMemFromBtree() does not need to be zero-terminated. (check-in: e0af9a90 user: drh tags: trunk) | |
| 17:49 | Small size and performance optimization in the bytecode engine. (check-in: 3b3e32d4 user: drh tags: trunk) | |
| 10:47 | Improved resolution of large integer values in "CAST(x AS NUMERIC)". (check-in: 7f2bd4ff user: drh tags: trunk) | |
| 09:09 | Updates to the "lemon.html" document received from Andy Goth. (check-in: 5b2002f3 user: drh tags: trunk) | |

| 22:04 | • Fixed ticket [1ec41379]: Integer multiple fails to overflow to floating-point plus 5 other changes (artifact: db310877 user: drh) | |
| 22:04 | Improved implementation of 64-bit signed integer multiply that correctly detects overflow (and promotes to floating-point) in some corner cases. Fix for ticket [1ec41379c9c1e400] (check-in: db3ebd7c user: drh tags: trunk) | |
| 20:33 | • New ticket [1ec41379] Integer multiple fails to overflow to floating-point. (artifact: 6af4ab88 user: drh) | |
| 17:49 | Fix harmless compiler warning. (check-in: 72429063 user: mistachkin tags: trunk) | |
| 17:38 | Fix typo in comment. (check-in: bd3ecbb5 user: mistachkin tags: trunk) | |
| 01:46 | Further performance enhancements in zeroblob() handling. (check-in: 21b0e3b7 user: drh tags: trunk) | |
| 01:19 | Avoid unnecessary calls to ExpandBlob() for smaller and faster code. (check-in: 5e196fd1 user: drh tags: trunk) | |
