Found all these from nix-repl. Use builtins.fetchTarball for nixpkgs pinning!

builtins.fetchurl
builtins.fetchTarball
pkgs.fetchFromBitbucket
pkgs.fetchFromGitHub
pkgs.fetchFromGitLab
pkgs.fetchFromRepoOrCz
pkgs.fetchFromSavannah

Lower precedence means a stronger binding; ie. this list is sorted from strongest to weakest binding, and in the case of equal precedence between two operators, the associativity decides the binding.

Prec	Abbreviation	Example	Assoc	Description
1	SELECT	e . attrpath [or def]	none	Select attribute denoted by the attribute path attrpath from set e. (An attribute path is a dot-separated list of attribute names.) If the attribute doesn’t exist, return default if provided, otherwise abort evaluation.
2	APP	e1 e2	left	Call function e1 with argument e2.
3	NEG	-e	none	Numeric negation.
4	HAS_ATTR	e ? attrpath	none	Test whether set e contains the attribute denoted by attrpath; return true or false.
5	CONCAT	e1 ++ e2	right	List concatenation.
6	MUL	e1 * e2	le

If you want a run-down of the 1.3 changes and the design decisions behidn those changes, check out the LonestarElixir Phoenix 1.3 keynote: https://www.youtube.com/watch?v=tMO28ar0lW8

To use the new phx.new project generator, you can install the archive with the following command:

$ mix archive.install https://github.com/phoenixframework/archives/raw/master/phx_new.ez

Bump your phoenix dep

Phoenix v1.3.0 is a backwards compatible release with v1.2.x. To upgrade your existing 1.2.x project, simply bump your phoenix dependency in mix.exs:

Some notes for tricky things I've run into while packaging things for Nix...

Searching through package expressions in the master branch of nixpkgs

There is a code search available here. It's considerably more useful and accurate than GitHub's search.

Creating your own package 'repository'

This article explains that.
