Hello Magnus,

I don't mean "downloadable from Hackage" I mean "used when compiling packages on Hackage". Follow the link and you'll see what I mean :-)

I'm not sure why building of my recently uploaded version of dataenc fails to build on Hackage[1]. Where can I find out what version of base is available on Hackage?

The build client uses ghc 6.10.2 (including base 4.1.0.0).  I'm not sure why base went up a major version number between minor releases of GHC.

Ah, that explains the failure to build. Does your second comment mean that it's safe to put the version limits to ">= 4.0.0 && < 4.2"? /M -- Magnus Therning (OpenPGP: 0xAB4DFBA4) magnus＠therning．org Jabber: magnus＠therning．org http://therning.org/magnus identi.ca|twitter: magthe

The upper bound will be fine now, but I don't know what version of base will be released with GHC 6.10.3. Shouldn't the lower bound be 4.0.0.0?

I'll put it as <4.2 then, for now. Well, if I understand the proposed package versioning policy[1], then A.B.C is equivalent to a specific API. /M [1]: http://haskell.org/haskellwiki/Package_versioning_policy -- Magnus Therning (OpenPGP: 0xAB4DFBA4) magnus＠therning．org Jabber: magnus＠therning．org http://therning.org/magnus identi.ca|twitter: magthe Haskell is an even 'redder' pill than Lisp or Scheme. -- PaulPotts
