Has version "2026" killed the ability to downgrade a project to a previous version?

Question

We've all been there - needing to open a .prproj in an older version of PPro, using the "rename it to .zip, extract it, edit the version name, etc" method or https://www.joshcluderay.com/downgrade-premiere-project-converter/ . When I tried to do this today (because the latest PPro beta is completely broken), it didn't work - ther resulting file (from Josh's automated method) didn't open in PPro 2025 (got the "it's too new" message) and when I did it manually, it just crashed PPro 2025 upon open.

So Adobe - have you killed off this essential, much valued workaround? Are you planning to fix it with something akin to AE's "save as previous version" command (please)?

@hellopaul4 We are considering options for backwards compatibility, but we have nothing to announce at this time.

We haven’t intentionally prevented downgrading tools from working with Premiere v26. As you likely know, those tools only change the internal version number without modifying the project data itself. However, in v26, the project data structure has changed significantly – largely due to the new Object Mask feature. Because of this, a v26.x file that has had its version number changed cannot be parsed correctly by v25.x or earlier, leading to the crashes or error messages you encountered.

Fortunately, there is a simple remedy for your current situation: you can open the project created in the v26.x beta directly in the shipping version of v26.0. The file formats are identical, so you can move your work out of the Beta environment without needing to downgrade the file.
