Pinecone has introduced a new approach to API versioning, balancing the need for innovation with the stability required by existing integrations. The company views an API as a crucial contract with users, and versioning is key to maintaining predictability and reducing integration disruptions. Pinecone has adopted a date-based versioning schema, communicated via a custom header, to provide clarity and transparency regarding the age and stage of each API iteration. This method allows for more frequent incremental improvements and simplifies the upgrade process for developers. Pinecone plans to release new stable API versions quarterly, with each stable version supported for at least 12 months, while release candidates preview upcoming changes three months in advance. This strategy aims to ensure a seamless and productive experience for developers by minimizing unexpected disruptions and offering clear communication about API evolution.
