2020-05-22 drh Version 3.32.0
2020-05-21 drh Change a NEVER macro into a NO_TEST comment, as the conditional is reachable, but only when compiling for Windows 32-bit.
2020-05-21 dan Avoid another potential OOB read in sqlite3expert.c.
2020-05-20 drh Back out the change from [7fab1393c2b22b1f] that tries to convert invalid surrogate characters in UTF16 into the replacement character 0xfffd, as we find that this breaks some software.

2020-05-15 dan Fix SQLITE_OMIT_VIRTUALTABLE testfixture builds.

2020-05-13 drh Remove unused constant SQLITE_FUNC_COALESCE.

2020-05-08 drh New test cases added to test/fuzzdata8.db.
2020-05-08 drh Do not retry on a failed realloc() unless SQLITE_ENABLE_MEMORY_MANAGEMENT is available, meaning that the retry has some possibility of success.
(...)
2020-02-24 drh Disable the new analyzeG.test module if not building with STAT4.
2020-02-23 drh Fix a problem with ALTER TABLE for views that have a nested FROM clause. Ticket [f50af3e8a565776b].
2020-02-22 drh Do not activate the truthProb adjustment mechanism if the truth probability is less than the heuristic value, as there could be correlations unknown to stat4. Also add additional tracing output to make truthProb adjustments more visible.
2020-02-22 dan Add new test file analyzeG.test, containing a test for the change on this branch.
2020-02-22 drh When stat4 information is available, try to use it to improve the truth probability of WHERE clause terms that do not participate in the index.
2020-02-22 drh In the OP_Column opcode, if the cursor is marked NullRow (due to being the right table of a LEFT JOIN that does not match) and the cursor is the table cursor for an OR-optimization with a covering index, then do not substitute the covering index cursor, since the covering index cursor does not have the NullRow flag set. Ticket [aa4378693018aa99]
2020-02-20 dan Add test case for previous commit.
2020-02-20 drh Early-out on the INTERSECT query processing following an error.

2020-02-17 drh A better (smaller and faster) solution to ticket [4374860b29383380].
2020-02-17 drh Take care when checking the table of a TK_COLUMN expression node to see if the table is a virtual table to first ensure that the Expr.y.pTab pointer is not null due to generated column optimizations. Ticket [4374860b29383380].
2020-02-16 drh Avoid an infinite recursion on an illegal recursive definition of an fts5vocab table.

2020-02-13 drh Fix an incorrect assert() statement that was added yesterday. Tickets [41c1456a6e61c0e7] and [fb8c538a8f57ae2a].

2020-02-12 dan When determining whether an == or IS constraint in a WHERE clause makes an ORDER BY term redundant, consider the collation sequence used by the == or IS comparison, not the collation sequence of the comparison expression itself. Possible fix for [fb8c538a8f].

2020-02-01 drh On an INSERT or UPDATE, perform affinity conversions on new data prior to running CHECK constraints. Ticket [86ba67afafded936].
