Releases · google/mtail

This release is made in honour of @junyer who sadly passed away this week. He was an influence in the early design and optimisations of the Google internal mtail version 2 series, and a generous and dear friend who I will miss very much. I hope he appreciates the irony that none of the changes in this release are related to regular automata, but do contain a fix for a silly performance issue.
