Draw the TreeView debugging graphs using unicode box-drawing characters. (Closed-Leaf check-in: 0efc6859 user: drh tags: box-character-graph)
19:04
Improvements to the new syntax-tree output routines: Omit the "END SELECT" mark and instead terminate the graph at the last item. Increase the maximum tree depth to 100. (check-in: 5ce05757 user: drh tags: trunk)

Enhanced debug output for OR-logic in the query loop optimizer. (check-in: 2e375eae user: drh tags: trunk)

12:33
Remove the SQLITE_ENABLE_TREE_EXPLAIN compile-time option. Add alternative debugging display routines: sqlite3TreeViewExpr(), sqlite3TreeViewExprList(), and sqlite3TreeViewSelect(). (check-in: 4ff51325 user: drh tags: trunk)
