Features
Fixes
- :bug: [cherry-pick: release-v1.9.x] fix(resolvers): Allow ResolutionRequests to resolve all Tekton kinds (#10253)
efore this change, ResolutionRequests could only resolve Pipelines, Tasks, and StepActions. After this change, ResolutionRequests can resolve PipelineRuns, Pipelines, TaskRuns, Tasks, Runs, CustomRuns, and StepActions.
- :bug: [cherry-pick: release-v1.9.x] Fix cross-arch platform command lookup in entrypoint (#10163)
ix entrypoint command lookup when controller and worker nodes run on different CPU architectures (e.g., ARM controller with AMD64 workloads). The controller's CPU variant was leaking into TEKTON_PLATFORM_COMMANDS keys via platforms.NewPlatform(), causing "could not find command for platform" errors on worker nodes of a different architecture.
- :bug: [release-v1.9.x] fix: surface clear errors when completed tasks miss referenced results (#9973)
ipelineRun status now shows which specific results were missing when tasks are skipped due to uninitialized result references from completed tasks. A Warning event with reason ResultValidationFailed is also emitted for consistency with other failure modes.
- :bug: [cherry-pick: release-v1.9.x] fix(resolvers): validate data is Tekton object in resolver framework (#9961)
Fixes a bug which lets Tekton Resolvers resolve non-tekton objects and arbitrary data. After this change, resolving a non-tekton object causes the ResolutionRequest to fail.
Action Required: Tekton Resolvers are now only permitted to resolve StepActions, Tasks, and Pipelines. Custom resolvers or ResolutionRequest which use the Resolver API for other object types will no longer function.
- :bug: [cherry-pick: release-v1.9.x] fix: bump google.golang.org/grpc to 1.79.3 (CVE-2026-33186) (#9908)
ump google.golang.org/grpc from 1.77.0 to 1.79.3 to fix CVE-2026-33186 (gRPC-Go authorization bypass via missing leading slash in :path header).
