| 00:49 | Add the SQLITE_RUNTIME_BYTEORDER compile-time option to force SQLite to check the processor byte-order at run-time. Add additional compile-time byte order checks for ARM, PPC, and SPARC. (check-in: 2c5363873a user: drh tags: trunk) | |
| 00:08 | Preliminary changes to support building VSIX packages for Windows Phone 8.1. (check-in: a1b2f28ba8 user: mistachkin tags: vsixWinPhone81) | |
