Sonic v1.9.0

on GitHub

This version introduces substantial performance improvements to PUSH requests.

While most improvements should benefit all Sonic users, some new experimental features were introduced to address specific high-scale needs which shouldn’t be a concern for most users. For now those API introductions are hidden behind the experimental-api feature flag, which won’t be enabled in official builds of Sonic. We’ll take those out of the experimental stage after using it in production and confirming that the chosen design is a good long-term choice.
