NOTE: This release contains several breaking changes!

• Upgrading build infrastructure
  • compile libsass 3.2.0
  • allowing builds without forced download of libsass.git every time
  • providing emscripten debug mode
• improving emscripten_wrapper.cpp to use sass_context.h instead of the deprecated sass_interface.h
• renaming files to make more sense
• improving synchronous API to perfectly mirror the worker API
• adding .options('defaults') to reset options to sass.js defaults
• adding dist/libsass.js.mem, optimized memory file created by emscripten
• adding Sass.lazyFiles() and Sass.preloadFiles()
• adding Sass.clearFiles() to wipe all files known to Sass.listFiles()
• adding Sass.importer() to intercept file loading requests from libsass
• adding configuration options
  • precision - Precision for outputting fractional numbers (0 using libsass default)
  • indentedSyntax - Treat source string as SASS (as opposed to SCSS)
  • indent - String to be used for indentation (2 spaces)
  • linefeed - String to be used to for line feeds (\n)
  • sourceMapRoot - Pass-through as sourceRoot property
  • sourceMapFile - Path to source map file (enables generating source maps)
  • sourceMapContents - embed include contents in maps
  • sourceMapEmbed - embed sourceMappingUrl as data URI
  • sourceMapOmitUrl - Disable sourceMappingUrl in CSS output
  • inputPath - source map generation source (stdin)
  • outputPath - source map generation target

Breaking Changes

• synchronous API (formerly dist/sass.js and dist/sass.min.js) is now required to be loaded from a directory called dist relative to document.URL (irrelevant for use in Node!)
• synchronous API now has the exact same signature as the worker API, meaning responses are not returned, but passed to callback functions instead.
• Sass.compile() used to return the compiled CSS as string, it now returns an object
• distribution files renamed or removed for clarity
  • dist/worker.js removed
  • dist/sass.worker.js removed
  • dist/sass.min.js removed
  • dist/sass.worker.js renamed to dist/sass.js (public API for the browser)
  • dist/worker.min.js renamed to dist/sass.worker.js (emscripted libsass for the web worker)
  • dist/sass.js renamed to dist/sass.sync.js (emscripted libsass synchronous API)
• source files renamed for clarity
  • src/libsass.worker.js renamed to src/sass.worker.js (contains the worker's onmessage handler)
  • src/sass.js renamed to src/sass.api.js (abstraction of libsass and emscription)
  • src/sass.worker.js renamed to src/sass.js (public API using postMessage to talk to worker internally)
• example files renamed for clarity
  • sass.sync.html added
  • console.html renamed to sass.source.html
  • worker.html renamed to sass.worker.html
