Full list of changes since v0.1.0 v0.1.0...v0.2.0

This release was focused on adding core features that didn't make it in the first release, as well as some UX and stability improvements. The UI has been redesigned to use a dark theme which has been a popular request. Polar now supports the latest versions of LND v0.8.2, Bitcoin Core v0.19.0.1 and adds support for c-lightning v0.8.0. Future released versions of these Lightning & Bitcoin nodes can now be used without needing to release a new version of Polar. This feature will let you start using the new versions as soon as they are out. To maintain support for older LND versions which are not compatible with the latest bitcoind, Polar now supports running multiple bitcoin nodes in a single network. Have fun creating chain splits and block reorgs with the new ability to stop and start individual nodes as well :)

There are now 10 languages included (English, French, German, Spanish, Russian, Italian, Chinese Simplified, Portuguese-Brazilian, Japanese, Korean), though most are machine generated, so they need some love. Languages are now crowd-sourced via Crowdin. See the Help Translate section of the README for more details.

In the next release, the focus will be on tackling some of the feature requests submitted since the initial launch. If you have any suggestions or use-cases you'd like to see improved with Polar, please don't hesitate to open an issue.

Application Data Folder Moved

Be sure to stop all your running networks and close Polar v0.1.0 before installing v0.2.0!

When adding c-lighting v0.8.0, lightningd was unable to create the lightning-rpc socket file due to 'path too long' errors on Mac. Polar previously stored the data for nodes in ~/Library/Application Support/polar/data/networks/. This has now been changed to ~/.polar on all OS's. When you launch v0.2.0 for the first time, Polar will migrate your application data from the old folder location to the new location. This also means that the paths to certs & macaroons have changed. If you hard-coded them in your app, you'll need to update the paths.

Location in v0.1.0

  • Mac: ~/Library/Application Support/polar/data/networks/
  • Linux: ~/config/polar/data/networks/
  • Windows: ~/AppData/Roaming/polar/data/networks/
