I just pushed Firefly 0.4.1 to Rubygems. Updating is easy:
gem update firefly Don’t forget to restart your server, that’s all.
The 0.4.1 release covers the following changes:
Normalize URLs before shortening them. This prevents false duplicates. Validate URLs to be valid HTTP or HTTPS, don’t accept others. Closes #8 Don’t ask for the API key after shortening a URL with the bookmarklet. Show the highlighted URL separately. Closes #7.
