 ## Now
 
-* move out GHCup.Version module, bc it's not library-ish
+* try to run exe before upgrade (backup to ~/.ghcup/bin/ghcup.old)
+* allow to build 8.8
+* curl DL does not cache json
+* explain environment variables
+* add --keep=<always|error> option
+
+* allow to switch to curl/wget at runtime
+
+* cross support
+* installing multiple versions of the same
+
+* proper test suite
+* add more logging
+
 
 ## Maybe
 
-* maybe: changelog          Show the changelog of a GHC release (online)
+* version ranges in json
 * sign the JSON? (Or check gpg keys?)
 * testing (especially distro detection -> unit tests)
 
 ## Later
 
-* i386 support
 * add support for RC/alpha/HEAD versions
 
 ## Cleanups
 
-* too many decodeutf8
 * avoid alternative for IO
 * use plucky or oops instead of Excepts
 
 ## Questions
 
+* move out GHCup.Version module, bc it's not library-ish?
 * mirror support
 * interactive handling when distro doesn't exist and we know the tarball is incompatible?
 * ghcup-with wrapper to execute a command with a given ghc in PATH?
