DIZipWriter 6.8.0
- New TYuZstdCompressor: Compress using the modern Zstandard compression algorithm.

DISQLite3 5.36.5
- Fix defects in the new ALTER TABLE DROP COLUMN feature that could corrupt the database file.
- Fix an obscure query optimizer problem that might cause an incorrect query result.

DISQLite3 5.36.4
- Yet another patch release to fix obscure problems in features associated with SQLite 3.35.0:
  - Fix segmentation fault and error reporting in new RETURNING feature.
  - Fix defect in query planner optimization related to EXISTS operators in the WHERE clause.

DISQLite3 5.36.3
- Fix a handful of problems discovered in prior releases:
  - Enhance the OP_OpenDup opcode of the bytecode engine so that it works even if the cursor being duplicated itself came from OP_OpenDup.
  - When materializing correlated common table expressions, do so separately for each use case, as that is required for correctness.
  - Improvements to error messages generated by faulty common table expressions.
  - Fix to the SELECT statement syntax diagram so that the FROM clause syntax is shown correctly.
  - Improvements the xBestIndex method in the implementation of the wholenumber virtual table extension so that it does a better job of convincing the query planner to avoid trying to materialize a table with an infinite number of rows.

  - Ensure that date/time functions with no arguments (which generate responses that depend on the current time) are treated as non-deterministic functions.
  - Limit the new UNION ALL optimization so that it does not try to make too many new subqueries.

DISQLite3 5.36.1

- Fix inifinite loop with invalid UTF-8 mode enabled.
- Fix multiple JIT problems, including character ranges optimization, character set matching, and word boundary check.

YuOpenSSL 0.3.0 Beta
- Update to OpenSSL 1.1.1i, with fix for a high risk potential NULL pointer de-reference in GENERAL_NAME_cmp.
- Add more than 150 new OpenSSL API functions.
- New Synapse TCP/IP and serial library support.
