• 🎊 Happy holidays and a Happy New Year! Please contribute to our long-running NATS end-user survey!

• 📱 Working on a 5G project? The community has increasingly expressed interest in how to best implement NATS as part of 5G infrastructure projects. Both across clouds and for private 5G implementations.  To better understand the requirements & emerging market opportunity Synadia participated in the 5G Open Innovation Lab ecosystem program. We met with dozens of thought leaders, 5G startups, and global 5G hardware & software providers and found several consistent themes for NATS. If you have a 5G project please let us know! for more information on the Innovation Lab, visit https://5goilab.com.

• 🧪 The Rust and Go clients now have experimental support for the new Service API! A preview version of this was introduced and demonstrated at RethinkConn 2022 titled, What might a native NATS service API look like?

• 💥 Jamie Gaskins, the author of the NATS Crystal client, added several examples to NATS by Example! See the resources section below 👇 for direct links.
