- download progress is now visible in task bar
- esp-tooltip now lists all masters, highlighting the missing ones
- python plugin will now report a problem if the path contains a semicolon
- leak detection now (somewaht) works around the fact that we don't always get a stack trace
- bugfix: mod meta-file is now reliably created if it was missing
- bugfix: parser for nxm-links didn't handle numbers in the mod name
- bugfix: small memory leak
