Attending: Sanket Verma (SV), Justus Magin (JM), Ward Fisher (WF), Gābor Kovācs (GB), Alfonso Ladino (AL), Josh Moore (JM), Davis Bennett (DB), Jeremy Maitin-Shepard (JMS), Eric Perlman (EP)

TL;DR:

We kicked off the meeting with introductions, even though we didn’t have any new joiners today (as this was the last meeting for this year). DB gave a lightning talk on Pydantic-Zarr, where he showed the usage of the library he created. After this, SV discussed moving to ZulipChat, and that was the end of 2023 for the Zarr Community!
