What's new in Siril 0.9.1

Siril 0.9.1 is a stability release: it contains only 2 bug fixes compared to the previous version, Siril:0.9.0, in particular it handles the new gsl library version 2.0 that was released approximately at the same time as 0.9.0. See the changelog for more information.

A crash was also happening on the first launch of Siril, or when no configuration file was available. It has been fixed with 0.9.1.

Note: support for films such as AVI has been dropped and many functions of Siril will not work for them, in favour of the SER format. In a future release, we will allow their conversion to SER. In the mean time, only sum stacking should be working properly with them.
