There are some remaining issues that should be fixed before the 18.05 release, but aren't receiving much attention:
init requires double quotas when running under sequence #2755 https://github.com/genodelabs/genode/issues/2755 (init should request quota upgrades when needed) nit_fb: add optional transparency #2728 https://github.com/genodelabs/genode/issues/2728 (less important, but just needs to be merged) Framebuffer has_alpha() function #2723 https://github.com/genodelabs/genode/issues/2723 Noux: rmdir dir/ (trailing slash) does not work #2686 https://github.com/genodelabs/genode/issues/2686 Multiple rump-backed file-systems not supported by VFS library #2681 https://github.com/genodelabs/genode/issues/2681 Additional pixel format support #2045 https://github.com/genodelabs/genode/issues/2045 (important for a library i'm writing; just needs to be merged)
All of these should be fairly easy fixes, and at least 2 already have patches that just need to be merged.
