v4.9.0

Compatibility Notes

• [generator-common] Generated files now include a blank line between the copyright header and the file content. (118131d)
• [openapi-generator] Fields with contentMediaType: application/json and a contentSchema will now be typed as the contentSchema type instead of string. Re-generate your client to pick up the new types. (404dc92)

New Features

• [openapi-generator] Support contentSchema in OpenAPI 3.1 schemas: fields with contentMediaType: application/json and a contentSchema are now typed as the contentSchema type instead of string. Serialization to a JSON string is supported for multipart bodies via FormDataBuilder; non-multipart bodies are not yet handled. (404dc92)
• [openapi-generator] OpenAPI generator now supports OAS 3.1 input. This feature is experiemental. Use with caution. (5f6fe80)

Fixed Issues

• [connectivity] Extend OnPremise HTTP agent cache key to scope it more strongly.
  The cache key now includes the subaccount identity ensuring keep-alive sockets are not reused across tenants in multi-tenant technical user flows.
  If no stable identity context can be derived from the request, a fresh agent without keep-alive is created for each request.
  This matches the behavior of the previous implementation in SAP Cloud SDK v4.6.0 and lower, which did not cache agents in any case. (9f55261)
• [generator-common] readCompilerOptions now uses the TypeScript compiler API for tsconfig parsing, fixing support for JSONC (comments, trailing commas), package-name extends (e.g. @tsconfig/node18), and circular extends chains. (88c304e)
• [http-client] Restore proxy authorization headers for same-origin redirects when using proxy configuration. (05e9299)
