The Full Stack Radio podcast has posted their latest episode interviewing Jason McCreary about the Laravel Shift service - a tool that helps you upgrade your Laravel applications more automatically and keep them up to date. It's a commercial service, though, and not an open source tool but there is a demo pull request you can see to get an idea of how it all works.
In this episode, Adam talks to Jason McCreary about building Shift, a tool that automates upgrading your application between framework versions.
Other topics mentioned in the episode also include PocketBracket, Laravel Cashier and the abstract syntax tree functionality (added to PHP in PHP 7.0).
