System Information
Operating system: Windows 10
Graphics card: Nvidia RTX 2070 Super

Blender Version
Broken: 4.0
Worked: 3.6.5

Video clips that have been previously retimed have had their timings reset in projects created prior to 4.0, completely breaking existing projects.
Also, it seems that it doesn't adjust the timing for the entire clip. In a broken project, it won't adjust clip length to fit retiming percent. It creates a new retiming key instead and leaves some portion of the clip at seemingly 100% speed, even though it reports it as being some percent lower than that, I am unable to reproduce the latter issue in a fresh project however.

The first file is a clean project, just created in 3.6.5 to demonstrate the retiming issue, the second file is a stripped version of file I discovered the issue on, and demonstrates the retiming issue where it inserts keyframes instead of retiming the entire clip.

-Create a video project in a pre-4.0 version of Blender.
-Add a video clip to it, retime it to something other than 1.0
-Open the project in 4.0

Hi, thanks for the report. AFAICS, the retimed strip from 3.6 is restored to default (without speed factor) when launched in 4.0.

Did I understand the reported problem correctly? or I missed something?
