The most recent version adds better support for the Austrian and Swiss varieties of German.
Yesterday it was brought to my attention that this project's main downloadable file "german.7z", the compressed word list, was broken on all SouceForge mirrors for several days. Hundreds of users worldwide ended up with a corrupted download.
The problem was caused by an upload that was terminated prematurely without notifying me about the failure. Data in the Subversion repository wasn't affected.
The problem is fixed now. I apologize for any inconveniences.
The binary Aspell dictionaries now feature greatly improved support for Swiss spellings!
