Where is Slapp?

Bolt wouldn't be possible without all the amazing work from Slapp contributors and community - it evolved from the Slapp codebase. Slapp will continue to be supported on the v3 branch but we'd really like existing Slapp users to give Bolt a try. We've been mindful to make sure Slapp apps will translate over without too much pain, and will be publishing a migration guide in the future.
