General improvements:
Added support for LIKE, GLOB, and REGEXP operators on virtual tables.
Added the colUsed field to sqlite3_index_info for use by
the sqlite3_module.xBestIndex method.
Enhance the PRAGMA cache_spill statement to accept a 32-bit integer
parameter which is the threshold below which cache spilling is prohibited.
On unix, if a symlink to a database file is opened, then the corresponding
journal files are based on the actual filename, not the symlink name.
Added the "--transaction" option to sqldiff.
Added the sqlite3_db_cacheflush() interface.
Added the sqlite3_strlike() interface.
When using memory-mapped I/O map the database file read-only so that stray pointers
and/or array overruns in the application cannot accidentally modify the database file.
Added the experimental sqlite3_snapshot_get(), sqlite3_snapshot_open(),
and sqlite3_snapshot_free() interfaces. These are subject to change or removal in
a subsequent release.
Enhance the 'utc' modifier in the date and time functions so that it is a no-op if
the date/time is known to already be in UTC. (This is not a compatibility break since
the behavior has long been documented as "undefined" in that case.)
Added the json_group_array() and json_group_object() SQL functions in the
json extension.
Added the SQLITE_LIKE_DOESNT_MATCH_BLOBS compile-time option.
Many small performance optimizations.
Portability enhancements:
Work around a sign-extension bug in the optimizer of the HP C compiler on HP/UX.
(details)
Enhancements to the command-line shell:
Added the ".changes ON|OFF" and ".vfsinfo" dot-commands.
Translate between MBCS and UTF8 when
running in cmd.exe on Windows.
Enhancements to makefiles:
Added the --enable-editline and --enable-static-shell options
to the various autoconf-generated configure scripts.
Omit all use of "awk" in the makefiles, to make building easier for MSVC users.
Important fixes:
Fix inconsistent integer to floating-point comparison operations that
could result in a corrupt index if the index is created on a table
column that contains both large integers and floating point values
of similar magnitude. Ticket
38a97a87a6.
Fix an infinite-loop in the query planner that could occur on
malformed common table expressions.
Various bug fixes in the sqldiff tool.
