The release is announced in several blog posts, e.g.
- SQL Server Release Services: "SQL Server 2016 Service Pack 1 (SP1) released !!!".
- SQL Server Blog (Data Platform Insider): "SQL Server 2016 Service Pack 1 generally available".
The official descriptions on SQL Server 2016 SP1 editions from Microsoft is more a presentation than technical details.
The installation set on Service Pack 1 can be downloaded from Microsoft Download. The release information (KB3182545) gives the details on what is fixed, but as the information is a collection of links it will take some time to get through all the details.
The new version number after the upgrade is 13.0.4001.0, and the installation will restart the services.
The installation set is named "SQLServer2016SP1-KB3182545-x64-ENU.exe" and takes 551 MiB. If the installation set is unpacked it takes 733 MiB.
The installation can be with the GUI by executing "setup.exe" or by command line - as usual.
Log files are generated as by previous SQL Server installations and upgrades. Usually in a folder named with a timestamp in the path "%ProgramFiles%\Microsoft SQL Server\130\Setup Bootstrap\Log\", e.g. the folder name "20161116_205924".
According to the logfile "Summary_<servername>_<foldername>.txt" (5 KiB) the installation took about four minutes on my workstation. The logfile "Details.txt" (9.14 MiB) contain about 59000 lines in my case. Usually I only look into Details.txt when I have an installation error...
This was the initial - and common - findings. When I get more they will surface here.
