Anthropic Python SDK breaking changes
The 3 releases whose own notes call out a breaking change, out of 62 the archive holds. Scattered one per release page, this is a run nobody can see; gathered, it is the shape of how often Anthropic Python SDK asks you to change your code.

How this is decided
A release appears here because the word breaking is in the notes its publisher wrote, not because anyone here read the diff. That cuts both ways. A release that changed an API without using the word is missing from this page, and a release that used the word about something minor is on it. It is the publisher’s own signal, reported rather than judged, which is the same rule the security page follows.
