Dev Build 3072 is out now.
As initially discussed elsewhere, there's been a change to how build systems are selected in this build. Previously, you had to explicitly select a build system, or let Sublime Text choose one automatically.
In 3072, there's no notion of selecting a build system: firstly, Sublime Text will determine the set of relevant build systems, and if the last used build system is in that set, then it'll build with the last used one. If it isn't, or there is no last used build system, then it will prompt with all relevant build systems. Pressing primary+shift+b will always prompt to select a build system.
Build systems are determined to be relevant if their selector matches the current scope, or if their keyfile (e.g., Makefile for Make.sublime-build) is present in the project's most top level folder. If a build system defines neither a selector nor keyfile then it's deemed to always be relevant.
There has been a few improvements to minihtml, too, it now supports img, ul, and li tags, as well as the padding (and padding-left etc) css property, and background-color is supported on inline elements. img supports file, res and data URLs, for example:
