HAProxy known bugs list as of 2025-06-03 by branch and by version

The list of open issues is maintained here. The table below instead lists bugs which are already fixed in respective branches and allows to search them by version.

This table lists all versions emitted in all branches that are still maintained as well as the last branch that is not maintained anymore. This covers about 10 years of deployments and should be sufficient for most setups still found in field. The table contains one line per release date and one column per branch.

By clicking on a branch number you can see the status of pending bug fixes for this branch. By clicking on a specific version, you can see the list of all known bugs affecting this version and for which a fix was already made available in the same branch (ie a riskless upgrade). Think about regularly checking your versions against this table.

Last point. Please do not mirror this page, it is rebuilt every night and you would distribute outdated lists of bugs. If you want to mirror it and keep it up to date, please contact the project maintainers.
