22:52
Fix a branch that has become unreachable due to recent enhancements. (check-in: 81ab5e0d user: drh tags: trunk)
21:51
Improved security for VACUUM. This check-in combines the fixes of [ab0d99d0b5ede] and [27754b74ddf646] in a way that is less likely to to be broken by future changes. (check-in: 260fc696 user: drh tags: trunk)

Overhaul of EXPLAIN QUERY PLAN. The output is now in the form of a tree. More details of the query plan are shown, and what is shown is truer to what actually happens. (check-in: ff01bbda user: drh tags: trunk)

Optimizations to the new EQP framework. (Closed-Leaf check-in: 956fef36 user: drh tags: rework-EQP)

Enhance EXPLAIN QUERY PLAN to report the generation of constant rows using VALUES or just a SELECT without FROM. (check-in: c75eee69 user: drh tags: rework-EQP)

More test case updates. Tests are all running now. (check-in: dab5e529 user: drh tags: rework-EQP)

Fix test cases so that they work with the new EXPLAIN QUERY PLAN output format. Only some of the cases have been fixed. This is an incremental check-in. (check-in: 5f0e803e user: drh tags: rework-EQP)
