19:52 | Improved comments on the sqlar.c and compress.c extensions that describe the differences between the "zlib format" used by SQLAR, the raw deflate format used by ZIP, and the custom format used by compress.c. No changes to code. (check-in: c13415c5ca user: drh tags: trunk) | |

21:46 | The shell detects and opens ZIP archives using the zipfile extension. (check-in: 05c99eb8ce user: drh tags: trunk) | |
19:19 | In the shell, include the ".archive" command only if compiling with SQLITE_HAVE_ZLIB. Add ".archive" to the ".help" output. (check-in: 366469f560 user: drh tags: trunk) | |
