Pre-deployment checklist
- Ask the community about any important gadgets or user scripts that are supposed to work while viewing Special:Block.
- Inform the community that any script that uses the block API and is supposed to do re-blocking may need to be updated to work on multi-blocked targets.
- Similarly the unblock API requires an id to be given if the target has multiple active blocks.
- Most use-cases involve (re)blocking or unblocking when the target has zero or one blocks, and will continue to work as it did before.
- We can try searching ourselves with a search like insource:Block on pages in the MediaWiki namespace. Note however that some scripts may use the localized form of Special:Block, so "Block" by itself may miss things.
- Point volunteer developers to https://www.mediawiki.org/wiki/Help:Manage_blocks/Developers
- If there are conflicting gadgets/scripts, ask an engineer to investigate.
