Anthropic Python SDK 0 to 1

Every Anthropic Python SDK 1.x release the archive holds, 5 of them, starting at 1.0.0 and running to 1.4.0. The publisher writes these one at a time and its documentation describes the version you are on, so the run between two majors is not laid out anywhere as a list.

The turn

The last 0.x release the archive holds before the turn is 0.125.0, on 19 Aug 2026. 1.0.0 followed a day later. The archive holds no 0.x release after 1.0.0 opened.

Tagged breaking

4 of these releases carry the breaking label: 1.4.0, 1.3.0, 1.2.0, 1.0.0. The label is matched from words in the publisher’s own notes, so a release that changed an API without using the word does not carry it.
