Thanks to the last successful campaign, they were able to work on performance improvements and add several features (such as Instant Preview and Animation Support), most of which are in krita 3.0 beta available for download.
This year the work will focus mainly on two well-known issues in Krita: text and vector tools. They were written, at first, to be office applications tools, as such, they are useful for simple stuff, while now developers want to make them really suitable for illustrators and graphic designers.
Also, if the main funding goal will be reached, there are several stretch goals related to both small and bigger improvements and new features. The biggest one is Python scripting.
For detailed informations about the goals and to give your support, go to the kickstarter page of the campaign.
