Disclaimer: I don’t work for Canonical (I applied recently and was rejected lol), and this is not an official news release. I’m just a man that noticed these things and wanted to make others aware.
If you type snap info core26, the latest/stable channel has finally been released as of 2026-04-29. However, it appears that the Ubuntu Core 26 .img files are not available as of the date of this posting (no 26/ folder [here](Index of /ubuntu-core)). Its kind of hard to tell if the .img is anywhere else because the canonical website is struggling to serve pages at the moment.
I also found this “latest” track of documentation about migrating from core24 to core26: https://documentation.ubuntu.com/snapcraft/latest/how-to/change-bases/change-from-core24-to-core26/
I tried upgrading my antennas snap from base: core24 to core26 and then rebuild but got an error message asking me to set [build-base: devel](https://documentation.ubuntu.com/snapcraft/stable/explanation/bases/), so I suppose its not ready for that just yet.
Seems like its getting close. Exciting stuff! Keep an eye out for a more official announcement.
