I find it hard to know if there's have been any new features added for each GrapheneOS release.
For example, recently with https://grapheneos.org/releases#2024053100 Duress PIN was added, posts about new releases looks like just some "bug fixes and performance improvements" and doesn't highlight any features/major improvements/bug fixes in release posts which users might be following/anticipating.
I recommend highlighting them in social posts for future releases, thanks for the amazing development on GrapheneOS!
