15:58 | Improved analysis and usage of indexed expressions in the query planner. (check-in: f889369638 user: drh tags: index-expr) | |
14:27 | Merge the latest enhancements from trunk. (check-in: 7bde6d4d8c user: drh tags: index-expr) | |
2015-08-29

19:41 | Enhance the json_extract() function so that if given multiple PATH arguments it will return a JSON array with all of the answers. Also update comments within the json1 extension to reflect stricter interpretation of JSON and PATH arguments. (check-in: 1da60c3dda user: drh tags: trunk) | |
2015-08-27

23:42 | Fix the OR-optimization so that it always ignores subplans that do not use an index. (check-in: cf452028d1 user: drh tags: index-expr) | |
