@ -7,6 +7,8 @@
- added vips_image_hasalpha()
- added vips_thumbnail() / vips_thumbnail_buffer()
- better >4gb detect for zip dzsave output [Felix Bünemann]
- all loaders have a @fail option, meaning fail on first warning, though it
only does anything for jpg, csv, openslide
11/11/16 started 8.4.4
- fix crash in vips.exe arg parsing on Windows, thanks Yury
