There were so many times when I wanted to use some package, it has a version on repology, but when I open the project’s repo there are no tags.
Nowadays it is extremely easy to bump software versions according to semantic versioning and also to tag them, that it should go without saying that most OSS and proprietary projects could also follow that workflow.
There are many projects both language-specific and agnostic to manage the release (and tagging) process. My favorite agnostic one is tbump and I highly recommend it.
then, read the "raw" ORG files in 'posts' directory or make the HTML version executing the 'dev.sh' script (remember that you will need GNU Emacs to render the posts into HTML files).
Then, you can just git pull to read the news whenever you wish, maybe do it with cron or a script that will pull many repos at once, for example with this script.
