What
The code that sends events to plugins (add-ons that extend Claude Code) now includes a bottom value whenever that event has a default for it. The nearby code used for testing the interface was only renamed.
Why
Plugins receiving these events may now see a bottom value they did not get before.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
The finding does not say what `bottom` means or which events have a default for it.
