I've uploaded a pre-release version of PasswordSafe 3.29, plus the .po files with the new strings for translation.
Here are the main new/changed user-visible features:
 Empty Groups are now persistent (previously a group with no entries would 'disappear' if the database was locked or closed).
 The Last Modified and Password Modified date/times are initially set to show the entry's creation time, instead of being blank.
 When comparing databases, you can now display of the details of the entries' differences in the results dialog by right-click -> compare selected entries.
 You can now cancel a long running Compare, Merge or Synchronize database operation. Note: You should check the operation's report file to see if the operation was indeed cancelled. If not, you can undo it as all operations).
 Portuguese (Brazil) installation instructions added, thanks to Andreas. Find now only highlights/select the found entry. Password Expiration Date now correctly set when using intervals. Paste into the Notes field (Add or Edit entry) is now always in plain text. When generating passwords (Ctrl-P), the user is no longer prompted to save changes when pressing Esc if they have selected a Named Password Policy but not generated a password. Custom special symbol set now handled correctly in Generate Password dialog box. All date/time fields in the List view are now displayed using the user's "short date" format as specified via the Windows Control Panel "Region and Language" tab. Fixed crash with Generate Password switching to default policy with > 1 named policy. Add Group now works again. Password History is now correctly repaired during the automatic Validate on database open. Editing an entry's Notes using an external editor no longer adds blank lines and fully supports non-Latin characters. Test selected password policy now reflects any edits done to the policy. Notes Word Wrap during edit now works again.
Note that the English help text isn't quite ready yet, this will be announced separately.
Schedule: I'd like to release this version towards the end of June.
The files may be found in the directory that DK set up, which also includes tools and instructions for those interested in making their own dlls for testing:
The new files are under the 3.29pre folder in the above.
Thanks in advance for your help in making PasswordSafe accessible all over the world!
