What's new in Siril 0.9.8

Siril 0.9.8 is mostly a stability and speed improvement release. It contains in particular some bug fixes for Windows over to the previous version, 0.9.7 but also adds new features:

• Subpixel alignment for stacking, or more exactly half-pixel alignment, with the feature called simplified drizzle
• Lucy-Richardson deconvolution
• Sum stacking now runs in parallel
• Added the savepng command
• Added some options to the stackall command
• Accelerated the autostrech display

Noteworthy bug fixes:

• Gnuplot can be used on Windows to generate variable star or exoplanet curves
• Siril-created SER files could have out of order timestamped images, this is now fixed
• Allowing large SER files (> 4G) to be stacked
• Image sorting using FWHM in the image list has been fixed
