21:48 | Change the OP_SetCookie instruction to write the literal P3 value, not the value in register P3. (check-in: 6d7d4703eb user: drh tags: trunk) | |
20:12 | Improve performance of fts5 queries. (check-in: 2334e88244 user: dan tags: trunk) | |
17:20 | Number VDBE opcodes starting with 0 instead of 1, as this obviates the lower-bound test on "switch(opcode){...}", making the code smaller and faster. (check-in: 4c9222f75b user: drh tags: trunk) | |
