The major changes are:
* The evaluation is now driven by the declared options. In
particular, this fixes the long-standing problem with lack of
laziness of disabled option definitions. Thus, a configuration like
config = mkIf false {
environment.systemPackages = throw "bla";
};
will now evaluate without throwing an error. This also improves
performance since we're not evaluating unused option definitions.
* The implementation of properties is greatly simplified.
* There is a new type constructor "submodule" that replaces
"optionSet". Unlike "optionSet", "submodule" gets its option
declarations as an argument, making it more like "listOf" and other
type constructors. A typical use is:
foo = mkOption {
type = type.attrsOf (type.submodule (
{ config, ... }:
{ bar = mkOption { ... };
xyzzy = mkOption { ... };
}));
};
Existing uses of "optionSet" are automatically mapped to
"submodule".
* Modules are now checked for unsupported attributes: you get an error
if a module contains an attribute other than "config", "options" or
"imports".
* The new implementation is faster and uses much less memory.
I actually had this breeding in my nixpkgs overrides for a year and only
recently took the time to fix it and thus revive my video feeds :-)
The package uses a patch which is removing the dependency on gconf and
switches to storage within a shelve in ~/.miro/config instead.

Compiles fine on linux i686 and amd64. Adding myself as maintainer, even
though I'm not using the package by myself, but a friend is using it for
DJing from a NixOS live system I'm maintaining.

This uses a patch from Gentoo to disable Java support for now, as it is
not needed for supporting Mixxx (which is the package I'm preparing).
Hopefully, the patch will be applied upstream so we can safely drop it
here.

Currently, the command btrfs scrub start <filesystem> attempts to invoke the pthread_cancel
routine and ends with an error melibgcc_sssage about it being missing. This prevents btrfs
scrub status from maintaining proper statistics about the running scrub.
Close#1127.
* There now is full support for building Haskell packages as shared libraries
for GHC versions 7.4.2 or later. The Cabal builder recognizes the following
attributes:
- enableSharedLibraries configures Cabal to build of shared libraries in
addition to static ones. This option requires that all dependencies of
the package have been compiled for use in shared libraries, too.
- enableSharedExecutables configures Cabal to prefer shared libraries when
linking executables.
The default values for these attributes are arguments to the haskellPackages
expression.
* Haskell builds now run in a LANG="en_US.UTF-8" environment to avoid plenty
of build and test suite errors. Without this setting, GHC seems unable to
deal with the UTF-8 character encoding that's generally considered standard
in the Haskell world.
* The Cabal builder supports a new attribute 'testTarget' to specify the exact
set of tests to be run during the check phase.
* The ghc-wrapper attribute ghcVersion has been removed. Instead, we use the
ghc.version attribute, which exists in unwrapped GHC derivations, too.
