17:30		Do not check immediate foreign key constraints until the end of the statement. This matches the postgres behaviour. (check-in: 1a32149c user: dan tags: trunk)
15:51		Modify the ".dump" command on the CLI so that it always issues a PRAGMA foreign_keys=OFF at the top of the output. (check-in: 0755b9b6 user: drh tags: trunk)
14:45		Change the version number to 3.6.19. Fix a couple of incorrect testcase() macros associated with the new IS and IS NOT operators in expr.c. (check-in: e3b73394 user: drh tags: trunk)
