- API companies managing breaking SDK changes
- Worth noticing
- On the same 16 OpenAI SDK repositories, the team reports 14 successful upgrades for Breakwater and 1 for OpenAI’s migration tool.
Field notes
The workflow starts with release notes and migration documentation, then searches for affected imports, clients, responses, errors, and streaming calls. The page shows a concrete OpenAI example, including the change from engine= to model= and from dictionary-style response access to attributes. For Stripe, it says some repositories needed a new failing-before, passing-after test because their existing tests could not see the runtime break.
