v0.4.0

BrowserFS v0.4.0 comes with the following new features:

• New file systems:
  • OverlayFS: Overlay a writable synchronous filesystem over a readable file system, letting programs modify read-only data sources and storing only the changed files.
  • AsyncMirror: Mirror a synchronous file system to asynchronous storage.
    • If you pair OverlayFS with AsyncMirror, you can persist changes to a read-only filesystem to data stores like Dropbox or IndexedDB.
• BrowserFS should now work with your module system of choice!
  • CommonJS, AMD, UMD, exposing a BrowserFS global...
• Faster zip support via pako!
  • And by actually telling the inflate algorithm how big the inflated file will be...
• Bug fixes for EmscriptenFS
  • We now ignore certain types of ENOTSUP failures for operations that Emscripten likes to perform, but couldn't care less about. Previously, these failures caused Emscripten to prematurely terminate.

Some internal bits:

• Added dirty bit to PreloadFile to avoid unneeded syncs.
• Switched to Browserify for modules.
• Switched to Mocha for unit testing, and cleaned up unit tests.

Enjoy!
