14:57 | The session extension is disabled by default. To enable it using --enable-session on ./configure on unix and add SESSION=1 to the nmake on Windows. Or add -DSQLITE_ENABLE_SESSION and -DSQLITE_ENABLE_PREUPDATE_HOOK to build manually. (check-in: bcaa650e87 user: drh tags: trunk) | |
13:14 | Turn the session extension off by default. Enable using --enable-session on configure scripts, or using the SESSION=1 argument to nmake on Windows. (Closed-Leaf check-in: e462cde2a5 user: drh tags: session-make) | |
