As discussed in #3732
Similar to #3508

You can still browse the docs at the corresponding git tags.

Deployment of preview was torn down

Could you add a page linking to the old docs on github with links like:

• v2.5: https://github.com/woodpecker-ci/woodpecker/tree/v2.5.0/docs/docs/
• v2.4: https://github.com/woodpecker-ci/woodpecker/tree/v2.4.1/docs/docs/
• v2.3: https://github.com/woodpecker-ci/woodpecker/tree/v2.3.0/docs/docs/
• v2.2: https://github.com/woodpecker-ci/woodpecker/tree/v2.2.2/docs/docs/
• v2.1: https://github.com/woodpecker-ci/woodpecker/tree/v2.1.1/docs/docs/
• v2.0: https://github.com/woodpecker-ci/woodpecker/tree/v2.0.0/docs/docs/

What's the best place to add this?

Maybe a new page at docs/pages/versions.md

@qwerty287 I found a way to link the versions in the versions dropdown. Also moved the version explanation from the deployment overview page to this new version page.

Thanks, that's a good idea
