Short and slightly sheepish.
For a few weeks ATDT was being developed on two branches that never met. One carried 1.7.1 through 1.7.3, the other carried 1.7.4, and each release got built from whichever line I happened to be on. So 1.7.4 went out missing things that shipped before it, and anyone who upgraded from 1.7.3 to 1.7.4 quietly lost the logon tour. That;s on me.
1.7.5 merges the two lines. Everything from 1.7.1 through 1.7.4 is in this package, and the build now refuses to make a release from a branch that is missing one.
If you are on 1.7.4, you get the logon tour back, daily maintenance for DOS doors, the 1.7.1 door fixes, the 1.7.3 engine work, and a FOSSIL that can tell the time.
If you are on 1.7.3, you get everything in 1.7.4: the MySQL door crash fix, the cursor at every prompt, delete-line handled properly.
The merge audit also turned up four real bugs, including one where a door that shelled out to another program could kill its own open files and die on the next read.

Overlay-upload as usual, data folder untouched. A board coming from 1.7.4 picks up one small database step on its first page hit.
