- Improvements to the Makefiles and build scripts used by VisualStudio.
- Fix an FTS5 issue in which the 'optimize' command could cause index corruption.
- Fix a buffer overread that might occur if FTS5 is used to query a corrupt
- Increase the maximum "scope" value for the spellfix1 extension from 6 to 30.
- SQLITE_SOURCE_ID: "2016-03-03 16:17:53 f047920ce16971e573bc6ec9a48b118c9de2b3a7"
- SHA1 for sqlite3.c: 3da832fd2af36eaedb05d61a8f4c2bb9f3d54265
Changes carried forward from version 3.11.0 (2016-02-15):
- Enhanced WAL mode so that it works efficiently with transactions that are
larger than the cache_size.
- Added the FTS5 detail option.
- Added the "EXTRA" option to PRAGMA synchronous that does a sync of the
containing directory when a rollback journal is unlinked in DELETE mode,
for better durability. The SQLITE_EXTRA_DURABLE compile-time option enables
PRAGMA synchronous=EXTRA by default.
- Enhanced the query planner so that it is able to use
a covering index as part of the OR optimization.
- Avoid recomputing NOT NULL and CHECK constraints on unchanged
columns in UPDATE statement.
- Many micro-optimizations, resulting in a library that is
faster than the previous release.
Enhancements to the command-line shell:
- By default, the shell is now in "auto-explain" mode. The output of
EXPLAIN commands is automatically formatted.
- Added the ".vfslist" dot-command.
- The SQLITE_ENABLE_EXPLAIN_COMMENTS compile-time option is now turned
on by default in the standard builds.
Enhancements to the TCL Interface:
- If a database connection is opened with the "-uri 1" option, then
URI filenames are honored by the "backup" and "restore" commands.
- Added the "-sourceid" option to the "sqlite3" command.
- Improved pthreads detection in configure scripts.
- Add the ability to do MSVC Windows builds from the amalgamation tarball.
- Fix an issue with incorrect sharing of VDBE temporary registers between
co-routines that could cause incorrect query results in obscure cases. Ticket
- Fix a problem in the sqlite3_result_subtype() interface that could
cause problems for the json1 extension under obscure circumstances.
Fix for ticket
- Escape control characters in JSON strings. Fix for ticket
- Reenable the xCurrentTime and xGetLastError methods in the built-in
unix VFSes as long as SQLITE_OMIT_DEPRECATED is not defined.
- Because of continuing security concerns, the two-argument version of
of the seldom-used and little-known fts3_tokenizer() function is
disabled unless SQLite is compiled with the SQLITE_ENABLE_FTS3_TOKENIZER.
