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.
+
Fix an issue with incorrect sharing of VDBE temporary registers between
+ co-routines that could cause incorrect query results in obscure cases. Ticket
+ d06a25c84454a.
+
Fix a problem in the sqlite3_result_subtype() interface that could
+ cause problems for the json1 extension under obscure circumstances.
+ Fix for ticket
+ f45ac567eaa9f9.
+
Escape control characters in JSON strings. Fix for ticket
+ ad2559db380abf8.
+
Reenable the xCurrentTime and xGetLastError methods in the built-in
+ unix VFSes as long as SQLITE_OMIT_DEPRECATED is not defined.
+
Backwards Compatibility:
+
Because of continuing security concerns, the two-argument version
+ of the seldom-used and little-known fts3_tokenizer() function is
+ disabled unless SQLite is compiled with the SQLITE_ENABLE_FTS3_TOKENIZER.
