Gregarius 0.5.0 was just released, you can download it from the sourceforge.net download page.
Changes since 0.4.2:
About 60% of the Gregarius code was rewritten into a slick, object oriented, system.
A WordPress-like theme engine has been implemented, allowing for much more powerful customization of the application’s look and feel
Feed and Folder collapsing, as well as feed updating, are now handled via AJAX.
An RSS feed for tags has been added.
Some 54 new features added and bugs fixed.
Está na hora de actualizar o agregador, tenho-o instalado na versão 0.4.2 com umas quantas falhas, acho que foi a bd, será que com esta nova versão isso desaparece? Vamos acreditar que sim!
