DEVONtechnologies has updated all three editions of (Personal, Pro, and Pro Office) to version 2.9.4 with sync-related reliability improvements and bug fixes for the personal information manager. The sync toolbar buttons now indicate unsynced changes (similar to the user interface found in the  iOS app), synced static and small items require less bandwidth and disk space thanks to better data chunking, and DEVONthink improves both Bonjour connection reliability and conflict handling with Dropbox.
The updates also fix an issue where WebDAV authentication could fail in OS X 10.10 Yosemite, resolve crashes related to sync stores and unreliable Bonjour connections, and fix a bug that prevented changes from being saved in a modified Web archive. (All updates are free. DEVONthink Pro Office, $149.95 new,; DEVONthink Professional, $79.95 new, ; DEVONthink Personal, $49.95 new, ; 25 percent discount for  on all editions of DEVONthink; 10.9+)
