Prominent new features of Choqok 1.6 include the renaming of the StatusNet microblog as GNU Social, which now lets users post medium attachments and send direct messages. For better security, the application now defaults to HTTPS (Secure HTTP) connections when available. Twitter support is also the main attraction of the Choqok 1.6 release, which features performance improvements to the loading of user lists, the ability to search for usernames and hashtags, support for viewing the original retweet time, support for deleting direct messages (DMs), and to send DMs with unlimited text.
