Release Notes

Heya, we're back with an exciting new release! We've been hard at work to improve Dat Desktop based on your feedback, and happy to put out a brand new version. With close to 100 commits since the last version a lot has changed!

New features 🔥

  • Dat protocol v2! - The all new Dat protocol has landed! The new protocol is faster ⚡️, more secure 🔒 and simpler 🙆. Read more about it in our design paper. Note that the new protocol is not backwards compatible and existing Dats will need to be reimported.
  • You can now edit the metadata of Dats you've created. Any changes will be automatically sent to all other peers, just like you're used to with updates to files.
  • We've reworked the import flow. You can now select where to download files, and get a lil preview of the data you're about to pull down.
  • When you first open Dat Desktop there's now a little tutorial to help guide you get started


  • We switched to using microcomponent for all our elements. This has allowed us to create a smooth UI running at 60fps that's great to compose.
  • We're now using a more efficient file watching algorithm which has greatly improved performance and simplicity.
  • We've improved the test suite. This should help with catching regressions and allow us to continue adding features with confidence.

Fixes 🏥

  • In nearly 100 commits we've created and fixed more bugs than we can count. We've been working hard to fix bugs so everyone has a great experience!

How can I speed up downloading Electron?

If you’re not in Europe or the US, you might want to use a different mirror for electron. You can set the ELECTRON_MIRROR variable to point to a different provider:

# Europe / US
$ npm install

# Asia / Oceania
$ ELECTRON_MIRROR="https://npm.taobao.org/mirrors/electron/" npm install
