Good to run through ReadMe though not many will do. Below are some key one that I see of interest
Not all Splunk apps and add-ons are compatible with Splunk Enterprise 6.4.

When you upgrade to version 6.4 of Splunk Enterprise, the software generates checksums for data model and report acceleration summaries as part of the migration. Migration time might increase significantly if there are a large number of data model or report acceleration summaries

The working directory for the inputcsv, outputcsv, and streamedcsv search commands has changed

For all versions of Splunk Enterprise, the number of source types that an instance can learn in the process of monitoring and indexing files has been limited.

Splunk Enterprise now identifies search commands that could negatively impact performance

Splunk Enterprise installs and runs two new services: App Key Value Store and App Server. This opens two network ports by default on the local machine: 8065 (for Appserver) and 8191 (for App Key Value Store.) Make sure any firewall you run on the machine does not block these ports.

Splunk has ended support for Splunk Web for Internet Explorer versions 9 and 10

There is no supported upgrade path from a Splunk Enterprise system with enabled Secure Sockets Layer (SSL) certificates to a system with FIPS enabled. If you need to enable FIPS, you must do so on a new installation.

Do also look out for the deprecated and removed features. Splunk does not provide a means of downgrading to previous versions. So do backup and  recover if required to rollback otherwise you must uninstall the upgraded version and then reinstall the previous version of Splunk Enterprise that you were using.
