In addition to numerous new and upgraded packages, this release has the following highlights: TODO

The following new services were added since the last release:

When upgrading from a previous release, please be aware of the following incompatible changes: lib.strict is removed. Use builtins.seq instead. The clementine package points now to the free derivation. clementineFree is removed now and clementineUnfree points to the package which is bundled with the unfree libspotify package. The netcat package is now taken directly from OpenBSD's libressl, instead of relying on Debian's fork. The new version should be very close to the old version, but there are some minor differences. Importantly, flags like -b, -q, -C, and -Z are no longer accepted by the nc command.

lib.attrNamesToStr has been deprecated. Use more specific concatenation (lib.concat(Map)StringsSep) instead. lib.addErrorContextToAttrs has been deprecated. Use builtins.addErrorContext directly. lib.showVal has been deprecated. Use lib.traceSeqN instead. lib.traceXMLVal has been deprecated. Use lib.traceValFn builtins.toXml instead. lib.traceXMLValMarked has been deprecated. Use lib.traceValFn (x: str + builtins.toXML x) instead. lib.traceValIfNot has been deprecated. Use if/then/else and lib.traceValSeq instead. lib.traceCallXml has been deprecated. Please complain if you use the function regularly. The attribute lib.nixpkgsVersion has been deprecated in favor of lib.version. Please refer to the discussion in NixOS/nixpkgs#39416 for further reference.
