1.21.7
(chore): Fix nil check in caller
1.21.6
(chore): Add GO_V2_PATH environment variable support for configurable v2 binary path during local development and testing
1.21.5
(fix): Fix duplicate test function generation in wire tests. When multiple endpoints map to the
same test function name, subsequent occurrences now get numeric suffixes (e.g., Test2, Test3)
to avoid Go compilation errors while preserving all test coverage.
1.21.4
(chore): Add sdkVersion as a top-level field in the generated metadata.json file.
1.21.3
(fix): Fix multi-URL environment resolution to fall back to client-level environment when
per-request environment is not specified. This ensures endpoints correctly resolve
their base URL when the environment is set at client construction time.
1.21.2
(fix): Fix retry logic to reset request body before each retry attempt.
1.21.1
(fix): Fix OAuth token handling for optional expires_in field. Use pointer conversion for optional
request fields and check ExpiresIn as pointer type with default fallback.
1.21.0
(feat): Add support for multi-URL environments via x-fern-server-name extension. APIs with multiple
base URLs per environment can now route different endpoints to different base URLs automatically.
The SDK generates a named Environment struct with fields for each base URL, and endpoints
resolve their base URL using the ResolveEnvironmentBaseURL function.
1.20.2
(fix): Fix OAuth token fetching to use GetOrFetch instead of GetToken.
1.20.1
(fix): Improve OAuth token fetching with concurrency protection and better error handling.
Multiple concurrent requests now share a single token fetch instead of each triggering
their own. Added nil pointer checks for OAuth responses and a 1-hour default expiry
fallback when the server doesn’t provide an expires_in value.
1.20.0
(feat): Add errorCodes config option with values per-endpoint or global. The global mode (default)
generates a shared error_codes.go file for all errors. The per-endpoint mode generates error
handling code inline for each endpoint, which is more robust for namespaced APIs or APIs where
different endpoints have different error schemas for the same status code.
1.19.0
(feat): Add OAuth token fetching support. The SDK now automatically fetches and caches OAuth tokens
using client credentials when configured. Tokens are refreshed automatically when expired.
1.18.4
(fix): Fix snippet generation for object types with optional fields that have no example value.
Previously, these fields would generate invalid Go code with <nil> instead of being omitted.
1.18.3
(fix): Fix handling of reserved identifiers in field names and make dynamic snippets match.
1.18.2
(fix): QueryValuesWithDefaults now handles nil inputs safely.
1.18.1
(fix): Fix linting in test files
