Version 0.4.4 brings a number of incremental improvements to BrowserFS:

• NPM package now exports TypeScript types!
  • So when you require('browserfs') from TypeScript code, it'll be typechecked.
• Improved SourceMaps that inline the TS source code.
  • In deployment scenarios, you only need .min.js and .min.js.map to trace back errors to the original TypeScript source.
• Buffer updated with Node v0.12 methods.
• SlowBuffer is now defined in the buffer module.
• Buffer now properly supports the noAssert option.
• Fixes for Emscripten integration (from beta 0.4.2 release).
• Fixes for Dropbox backend:
  • Now appropriately retries requests when rate limited or experiencing transient server / network errors.
  • More accurate error code generation / error message generation.
  • Avoids file transfers / directory reads when possible using Dropbox's hash and rev fields, respectfully.
    • Note: You'll still never receive a stale version of either, since we check with Dropbox to ensure our cache is up-to-date. And it doesn't add latency, as this functionality is baked into the Dropbox REST API.
• Fixes for IE8
  • Previously, we accidentally used delete as an identifier, which is a no-no.
  • NOTE: Actual IE8 not tested; I tested with IE10 in IE8 compatibility mode.
• Fixes for IE8 compatibility mode in IE10.
  • Previously, we chose an incorrect buffer backend in this scenario, since IE10's compat mode erroneously defines an unusable CanvasPixelArray.
• General code cleanup.
