Can you think of writing, and updating, a draft release notes / release announcement for each release?
Instead of simply writing Lubuntu xx.xx release, please head on here to download, can add set of features / improvements / updates introduced in the release.
It will be easier, if adding each point when it is getting implemented in the distribution and will be helpful for bloggers / vloggers / other media persons to prepare their reports and yell about Lubuntu to entire world.
Ubuntu Budgie is doing so - https://ubuntubudgie.org/2020/09/ubuntu-budgie-20-10-release-notes/
Just a suggestion. Don’t be rude on responses I know it not so easy to bring everything together. But this will help the project to get more community engagement and visibility.
