Walkthrough

The Dockerfile for sglang was updated to use a newer commit of the sglang repository. The comment above the commit reference was also expanded to document recent fixes, specifically mentioning a ZMQ KV event publisher fix as of 6/12, while retaining previous notes about earlier improvements.

Poem

A Dockerfile hops to a newer commit,
With ZMQ fixes—oh, what a hit!
Notes expanded, history kept clear,
Sglang grows stronger with each passing year.
