Endless OS 4.0.2 has been released as an over-the-air upgrade. The only notable change in this release is a fix for a regression in 4.0.1. There will be no new installation images since the regression only affected upgrades on existing systems, not new installations: 4.0.1 is fine for new installations.
Here’s the fix in question, taken from our wiki:
Web Safety internet connection issues
Computers with web safety enabled before upgrading to Endless OS 4.0.1 were no longer able to connect to the internet at all. This problem is resolved in this release.
If you are unable to go online after upgrading to Endless OS 4.0.1, open a Terminal window, type the following command, and press
pkexec eos-safe-defaults disable
Then restart your computer. If your problem is caused by this Web Safety bug, it should now be able to connect to the internet once again. Web Safety will be re-enabled when you update to Endless OS 4.0.2 or newer.
