+sp_AllNightLog, sp_AllNightLog_Setup, sp_BlitzInMemoryOLTP, and sp_BlitzQueryStore are no longer maintained. They may still work, but no guarantees. Please don't submit issues or pull requests to change them. You're welcome to fork the code and build your own supported version, of course, since they're open source.

+The other files in this folder are older versions of the First Responder Kit that work with versions of Microsoft SQL Server that Microsoft themselves no longer support. If you're cursed enough to work with antiques like SQL Server 2012, 2008, or heaven forbid, 2005, you may still be able to get value out of these, but we don't support the scripts anymore either.

 * SQL Server on Windows - all versions that Microsoft supports. For end of support dates, check out the "Support Ends" column at https://sqlserverupdates.com.

 * Amazon RDS SQL Server - fully supported.
 * Azure SQL DB - not supported. Some of the procedures work, but some don't, and Microsoft has a tendency to change DMVs in Azure without warning, so we don't put any effort into supporting it. If it works, great! If not, any changes to make it work would be on you. [See the contributing.md file](CONTRIBUTING.md) for how to do that.
