| As we will be backporting fixes from mainline, which [[https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Documentation/process/stable-api-nonsense.rst|may change in-kernel APIs]], we will not guarantee API or ABI stability within an SLTS branch. It is the responsibility of members to update any out-of-tree components they use in case they are affected by such a change. However, incompatible changes to user-space APIs or ABIs will not be acceptable. | As we will be backporting fixes from mainline, which [[https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Documentation/process/stable-api-nonsense.rst|may change in-kernel APIs]], we will not guarantee API or ABI stability within an SLTS branch.

| Although this goal may be achievable for CIP, its members may take much longer to release and deploy binary updates, maybe due to valid concerns about the risk of regression or limited opportunities to deploy updates. In the worst case, they may use CIP as an advertising/compliance point - please don't do that! | Although this goal may be achievable for CIP, its members may take much longer to release and deploy binary updates, maybe due to valid concerns about the risk of regression or limited opportunities to deploy updates.
