| 21:16 | Ensure that when the col in an operator like "val IN(col)" is a column of a view, its affinity is not used to coerce val. Fix for [0a5e2c1d]. check-in: 17b3d221 user: dan tags: trunk | |
| 20:55 | Improved reuse of file descriptors for which close() is delayed to prevent clearly of posix advisory locks. check-in: 509c1ba2 user: drh tags: trunk | |
| 20:26 | Enhance the ".recover" output in the shell to use double-quotes around table and column identifiers. check-in: 846d2d2d user: drh tags: trunk | |
