Upgrade Notices

  • [TEP-0104] Task-level Resource Requirements in now beta
  • Matrix is now beta
  • Starting with this release, all new API driven features will be controlled by individual feature flags, and the enable-api-fields flag will be eventually phased out, once all API features currently in alpha/beta reach stability (or are removed)

Changes

Features

  • ✨ parameterize pipelineTask (#7273)

displayName can now accept params, task result references, or context variables.

  • ✨ Hub resolver: add version constraints (#7257)

hub resolver can now specify a version constraint to choose a version (example: version: ">=0.2.0,< 1.0.0")

  • ✨ Set public Tekton Hub API as default catalog (#7256)

tekton resolver now uses hub.tekton.dev by default.

  • ✨ [TEP-0145] Add CEL field to WhenExpression

    • ✨ [TEP-0145] Add CEL field to WhenExpression, and feature flag to guard the field (#7247)
    • ✨ [TEP-0145] Add sanity check for CEL expression (#7251)
    • ✨ [TEP-0145] Add CEL evaluation (#7255)
      Support CEL expression in WhenExpression to guard the execution of Tasks

  • ✨ Add a setting disallowing access to all namespaces (#7237)

Add special value * to the blocked-namespace setting for the cluster-resolver to disallow by default all namespaces and only allow the namespaces explicitly listed in allowed-namespace setting.

  • ✨ [TEP-0104] Task-level Resource Requirements to beta (#7225)

The task-level resource requirements feature allows the user to set computeResources at runtime i.e. on TaskRun. This is now enabled as part of the beta API.

  • ✨ TEP-140: Produce Results in Matrix (#7167)

Pipeline authors can now produce results from a Matrixed PipelineTask as an aggregated array and consume them in an array params. Two context variables are introduced as part of this feature, $(tasks..matrix.length) to get the length of a matrix combinations and $(tasks..matrix..length) to get a length of aggregated result.

  • ✨ Promoting Matrix to Beta 🎉 🎓 (#7164)

Matrix feature is promoted to beta and possible to utilize with enable-api-fields set to beta.

  • ✨ TEP-0107: propagate results to embedded task spec (#7100)

Results are propagated in embedded specifications without mutations.

  • ✨ [TEP0138] Add Per-feature Flag Struct for New Features (#7090)

Please use per feature flags for new API-driven feature gating.

  • ✨ feat: add ability to include reason in count metrics (#7060)

Add ability to include reason along with status in TaskRun and PipelineRun count metrics

Backwards incompatible changes

In the current release:

  • 🚨 The behaviour of the enable-api-field flag has been fixed, resulting in a slight behaviour change: when using the v1beta1 API, API features in beta are only available when the enable-api-field is set to beta or alpha. Beta features used to be enabled on the v1beta1 API regardless of the value of enable-api-field.
    Note that:

    • The default value for enable-api-field is beta
    • Users that have the flag set to alpha or beta will continue to have access to beta features on v1beta1 and v1 APIs
    • Users that have the flag set to stable will continue to not have access to beta features on the v1 API

    So in practice, there is no breaking change for users. Users of the v1beta1 API may now disable beta features, should they wish to do so, which was not possible before.
