Is there an easy way to find a list of recommended patches for a specific Sitecore version/update? I can see that individual patches are recommended for a particular version but I can't find a a list of all recommended patches.
As commenters above have said, there isn't a definitive list of patches for a specific version.
Even though there is no definitive list of patches for a specific Sitecore version, the best approach to this is to contact Sitecore Support. By providing them your Sitecore version, they can easily pull out the list of recommended patches that you required.
I did a Sitecore upgrade from 7.2 to 8.1 and the 7.2 instance had several Sitecore patches. By contacting Sitecore Support, they told me which patch is still required on the Sitecore 8.1.
