new column build_id in user_assignment table

[Markus]

is there any possibility to set the build_id for previously testplans (before 1.9 RC1)? Currently I lost all testcase assignments for older releases, because there is no build id set. The assignments are still in database, but they are not displayed in Assigned Test case execution task page

This should be done on migration while updating from TestLink 1.8.
Have you skipped between betas without doing the migration process?

Previously we used TL1.9 beta1 - TL 1.9Beta5. Before that I have done an update and at this point I'm not able to run the update script (because TL says that my database schema is up to date)

Normally you should update from the last stable release to each beta (or RC). Migration between betas is not supported.
If you don't do that you have to take care of the changes to database schema between releases on your own.

Where is the migration documented, for dB changes? The change logs only list the issues addressed. I think use of Beta exposes most of the issues, and it is good. If Betas are not used in production environments, would take long time for issues to show up.
If you can point to the migration process or have it in changelogs, that will be great.
