Here’s the Rust development changelog, @RustUpdates.
To subscribe to this build, which will have your Steam downloading updates 10-25 times a day, go into the Betas tab and select “development” from the dropdown. I don’t recommend it, but that’s how it can be done if you want to check out the latest bleeding-edge updates.
The ‘standard’ branch of the new version of Rust (what used to be called experimental) generally gets updated every Friday, with the Friday devblog essentially being summarized patch notes.
However, on this past Friday, there was no update because, as garry explained in the devblog, building isn’t ready for unleashing on everyone and needs some more time in the oven, which is one of the focuses of this week. This means that everything since the changes introduced in Devblog 33 are not live on the main branch until garry’s ready to push the new building design out, and that includes cupboards.
In short, when garry has gotten the development branch to a point where he’s ready to push the update to everyone, the Steam version identifier for the normal branch gets updated to match the latest version of the development branch – which triggers the update to push the new version to everyone. After switching experimental to the default version, garry changed the non-developmental branch update frequency from 2-3/day to 1/week. Because building wasn’t ready, the development branch didn’t copy over onto the main branch. It would take extra work on garry’s part to revert all the building changes that aren’t ready and produce a build that does include the cupboard update but not the stuff that isn’t ready, and it’s just easier for him to… not update until it’s ready. Because if you want to try it, you can just flip the drop-down to development and try it without inconveniencing ~2 million people with a download for a patch garry doesn’t think is ready.
Switching to the development build means you’ll need to connect to development-branch servers, and usually won’t be able to connect to normal ones. It’s easy to switch back, however.
The “Days since last update” value is not counting real days since updating, I’m not sure what it’s counting but it’s flatly wrong as far as real time goes. Nobody outside Facepunch had heard of anything involving Rust two years ago, and it has certainly been updated since then.
