This bug first appeared in new installations of 4.0.24. It will be fixed in 4.0.25 on the stable branch.
In the 4.1.x branch, the wrong specification will be corrected for new installations of the next build. For existing installations, the database field vw_revision.textsize will be changed back to int when upgrading to Alpha 2.
This will mark the first occasion where both branches need to perform the same task. Thus, starting with the next 4.1.x build, it will maintain a separate record of the stable upgrade scripts that were run before upgrading to 4.1.x versions (people who upgraded to 4.1.x from 4.0.24 would not have run the upgrade steps for 4.0.27), so that we can make sure that steps needed by both branches are still run but are not run more than once by the upgrade from 4.0.x -> 4.1.x, even as 4.0.x and 4.1.x diverge in future versions.
