That is good advice, my goal with the article was however not to promote or require any special tools or platforms. The change log accompanies the release and your consumer might not have online access.
Anyway I do use the GitHub release facility in conjunction with the change log file accompanying my software myself. The software is distributed via other channels, I just copy my entry from the change log file into the text field for the GitHub release (see example Perl distribution example).
This would work for a lot of software, like Perl distributions or Visual Studio Code extensions etc. where the change log is being made available for consumption by the toolchain or similar. Other distribution channels do seem to approach this differently where nuget for .NET seem to lean on linking to facilities like the one you mention.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
