Notifications about ending OS support

[Falco20019]

I didn't find an issue with the os-support label (or any else regarding this). Support for Alpine 3.15 ended yesterday. Is there already a tracking issue? Is it planned to be dropped for .NET 6.0 and .NET 7.0?

We have an aggregated internal overview that I want to keep updated and for that I would like to track that if possible :)

You can consider support dropped, however, @rbhanda, do we have some paper work for that?

It is interesting to hear that you have an internal overview of this. Is there something we can do better to help with that? It is always interesting to us to hear about folks that have a structured program for such things. Feel free to respond here or mail us at [email protected] if you want to discuss this further.

Hi @richlander,

thanks for your interest. We are mostly tracking the upcoming end of support per product and the differences between the version (especially what is dropped). While the supported-os.md files would have a Out of support OS versions section, those are generally not well maintained. For example, the .NET 7 page shows only Fedora 35 and SUSE LES 12 SP2-4 as out of support. But I know that also Alpine Linux 3.15, Fedora Linux 36, openSUSE Linux 15.0 - 15.3, Ubuntu Linux 18.04 and macOS 10.x are EOS. Upfront, I totally understand that it's not your focus to keep those documents up2date all the time as it involves some work. But I find it confusing that there is a section on the support pages that shows some but not all EoS things. Personally, I have reminder for upcoming EoS dates in my calendar to know when an update to the list is required to not manually check it.

These are the lists we currently have internally:




You can ignore the light-red on .NET 7 and .NET 8 columns since these only have the internal meaning of "available without change but currently not used by us as we target .NET 6 LTS in our product". The dark-red means, there was a change in support towards the previous version.
The light-blue on "Upcoming EoS" means it's less then 1-2 months away. Dark-blue means EoS was already reached on .NET 6 for the one listed on the documentation page whereas the colum might already show the next upcoming EoS for that OS.

We also track the EoS OS (only those that were in support any time we used it):

We have somethine similar for .NET Framework in general (.NET 1.x to .NET 4.x is of course .NET Framework, only shortened for overview purposes):

And a second one (collapsed for better overview) from past versions that we might still have terminals in the wild we ran on:

The light bulb singalizes if the .NET runtime or OS is still in support or not by Microsoft. Green ticks mean supported by OS, green with stars is supported through backwards compatability by newer installed version, yellow means supported but not pre-installed and red means not supported. Blue means not interesting for us and therefore not checked/tracked.

To not create to many duplicates as @rbhanda will take care about the template, I will now only post them here.

The following OS went EOL recently (no os-support issues so far):

• OpenSUSE Linux 15.4 on December 2023
• Fedora Linux 37 on December 5th 2023

Mainstream support ended (extended support until 2029) for:

• Windows 10 v1809 on January 9th 2024
• Windows Server 2019 v1809 on January 9th 2024
• Windows Server Core v1809 on January 9th 2024
• Nano Server v1809 on January 9th 2024

Is it possible you could help us maintain this information in a way that would help your downstream scenario?

I really like the approach that you follow with the release.json files including CVEs. Maybe this could fit in there as having a list of supported-os on the same level as releases. I'm open to have discussions with you, the team and/or the community on that topic.
