Steps To Reproduce Regular build

[AlexandreRouma]

You're seriously reporting a "bug" for a 3 year old version?

You're seriously reporting a "bug" for a 3 year old version?

Did I miss a newer version? Where is it?

[AlexandreRouma]

SDR++ moved to a rolling release model 3 years ago. There are commits to the master branch on average almost every day. The source code in the link below is not automatically synched to the master branch. Pull from master for the latest stable source code. The master branch is defined as stable in this project. https://github.com/AlexandreRouma/SDRPlusPlus/releases/tag/nightly

I didn't know that, thanks.

@AlexandreRouma FYI: All other packagers aren't aware of the rolling release either: https://repology.org/project/sdr%2B%2B/versions The reason is that they go by GitHub tags which are automatically discovered by release auto-discovery systems.

Users have outdated , frozen versions, and these days users expect to have pre-built packages for everything.

You might want to do one of these things:

1. Reach out to maintainers of these packages.
2. Add tags like YYYYMMDD periodically, like once a month.
