Early access: Corporation Projects
Today we're announcing an early access period for new Corporation Projects routes in ESI. This early access will run for two weeks and be limited to developers in the EVE Partner Program. Feedback from this group will help us validate the design and make adjustments before going public.
Changing pagination: turning a new page
Today we're announcing changes to how ESI deals with pagination. This new system will be used for the first time with the introduction of Corporation Projects later this summer. We'll also be opening a discussion thread on Discord for Q&A and feedback from third-party developers.
Changing specs: from Swagger to OpenAPI
Today we're announcing changes to how we serve our API specifications. We'll also be opening a discussion thread on Discord for Q&A and feedback from third-party developers. Moving forward, we will be publishing our specs as OpenAPI 3.0 and 3.1, and no longer as Swagger 2.0. New updates will be made in the OpenAPI specs only, while we keep Swagger specs in a read-only mode around for a while. We are also introducing a new UI to view the specs.
Changing versions: /v42/ was getting out of hand
Today we're announcing changes to the ESI endpoint versioning strategy. Moving forward, new routes will no longer rely on versions embedded in their URL paths. Instead, we are introducing an X-Compatibility-Date header that works for the entirety of the API. Existing routes also adopt this new behavior, but we will continue supporting the versioned URLs for the foreseeable future.

The ship of ThESIus
Greetings, developers. Replacing RabbitMQ with… RabbitMQ? As we briefly touched upon in the EVE Evolved dev blog, one of our goals is to get ESI better connected to the Quasar ecosystem. Currently, ESI connects to the monolith via two distinct channels; sending Quasar protobuf messages, and sending ‘old’ JSON requests. Both of these go over...
