November 20, 2017

Version 1.21 is now available.

This release introduces share-groups, which allows you to selectively share your files with groups of users in your contact list or channels you select. New groups are created in the library, which has a separate checkbox column for each group in addition to the default public group. Then any user in your contact list can be right-clicked and added to any group. Chat rooms can also be added to groups, so that all users currently inside the chat will have access. It should be noted that both the local and the remote user must be using v1.21 or newer to see the non-public shares due to the need for upgraded authentication between clients.

We have also made numerous changes to our framework to fix several minor problems. Our unicode processor has been upgraded, and this has eliminated problems with sharing and searching in East-Asian character sets. A few problems with the Win32 directory enumerator have also been fixed so that NTFS symlinks and junctions will now work correctly.

There have also been several minor fixes in the GUI, especially in the GTK2 version.

More improvements and fixes are on the way soon.
