My v5 license is now valid through 23 Oct 2025 with a one year update plan purchased from Thomann.
According to the @Fleer history lesson:
Bitwig 5.0 June 29, 2023 (beta April 11)
Bitwig 4.0 July 13, 2021 (beta May 27)
Bitwig 3.0 July 10, 2019 (beta May ?
Bitwig 2.0 Feb 28, 2017 (beta)
I'm (possibly) good through all of the v5 lifecycle.
What is the typical version upgrade price for Studio? I've only jumped on board at version 5.
