Start by reviewing the January 2019 .NET Framework links and the linked .NET Core 2.1.7 and 2.2.1 release notes. Check whether any additional January releases belong in the issue, then update the release list if needed; done means the monthly announcement accurately covers January releases and retains the support-policy links.
