Both NNTPGrab 0.6 and trunk:
- Added the <TAB> character to the list of forbidden characters for collection names
- Dropped the SQLite3 dependency by using a custom file format for saving the download queue
This brings several performance improvements in download queue manipulation
Removing items from the download queue (even ones which are currently being downloaded) now happens instantly!
Old download queues (created using SQLite3) can't be converted to the new file format
