Xfer Records - Serum - Changelog / Release Notes This document is a manually compiled historical changelog for the Xfer Records Serum synthesizer, extracted from the official update API and converted to markdown. It lists release versions from 1.07b4 (November 2015) up to 2.0.24 (November 2025), and includes SHA256 hashes for verifying download authenticity starting from version 1.36b8. The page also provides context on where official release notes can be found, noting that access may require product ownership or a Splice account. Xfer Records - Serum - Changelog / Release Notes Note: This was originally extracted from the HTML returned from the https://xferrecords.com/api/update check/serum API, converted to markdown, and then formatted manually / cleaned up a bit further. It probably won't be kept strictly up to date, but it should at least serve as a useful historical record. Note: For releases that I had access to the .exe / .dmg / .pkg files for, I have also included the SHA256 https://en.wikipedia.org/wiki/SHA-2 hashes of the official downloads; so that they can be used to verify the authenticity of any versions that you might come across.
