Thanks for the update, HMR issue seems to be fixed. However, running the latest redis-oplog beta causes an issue in my project, cf. this post here.

Hello, this is great. If we use alanning roles what is the impact of the new core roles package ? Where is the doc of this new role package ? Is there a migration routine to move from alanning roles to the new role packages ? Thanks a lot.

The roles docs should be out soon, @dokithonon! You can check the PR here.

However, we don’t have a migration guide for alanning roles. That’s a great point!

I think there’s a part in the document mentioned about migration: Roles | Docs

A bit later than we wanted, but we just released a video where I talked to the core team about the new features and improvements of version 3.1: https://www.youtube.com/watch?v=u7Z-BKzIX4g

I’d love to get some feedback on it :slight_smile: We want to release videos in this format more often!

Finally got to watch this over breakfast today. BEAUTIFUL production value and AWESOME leadership tone for the now-direct Developer Relations approach. Was holding my breath to see how it would go but you guys leveled-up. As a team, it is inspiring to see the unity, power, focus, and enthusiasm with a sense of purpose.

Very cool to be able to believe in those on the front lines, and did not expect that feeling to come back so strong. Being proper ninjas and well put together as a squad is a gift to the community in and of itself.

Paying respect. Also, you guys sold me on moving to 3.1 straight away. I can see any hurdles with it will be overcome. And I can see the investment being made into the core is worth real faith from the community.
