Elsa 3.6.3 — Release Notes

Compare: 3.6.2...3.6.3

🌟 Highlights

• Azure Service Bus startup stability: Added an opt-in stable application instance name provider for clustered hosts so Azure Service Bus change-token subscriptions can be reused across restarts instead of leaking one subscription per random instance name. This addresses the startup/crash-loop failure mode reported in #7732 and #7736. (#7734)
• Long configured instance names: Configured stable application instance names that exceed transport entity limits are now shortened deterministically instead of failing startup, preserving stable identity for values such as Kubernetes pod names. (cb295d0b49)
• Blank Cron expressions restored: Blank or whitespace Cron values are treated as disabled/no trigger payloads instead of blocking workflow publishing, while invalid nonblank Cron expressions remain invalid. (#7739)
• Publish validation responses: Workflow publish endpoints now honor failed publish results and surface validation warnings/errors in API responses instead of reporting successful publication when validation failed. (#7740)

⚠️ Breaking changes / upgrade notes

• No intentional breaking changes are included in this patch release.
• Hosts using Azure Service Bus in clustered or frequently restarted environments should configure a stable application instance name for each process/pod. Long configured values are supported and shortened deterministically.

🔧 Improvements

• Clustering: Added an opt-in stable application instance name provider and related configuration for hosts that need deterministic per-instance transport identities. (28d6786042)
• Clustering: Deterministically shortens long configured application instance names while keeping the same configured value mapped to the same shortened value across restarts. (366ed74bd1, cb295d0b49)
• Workflow publishing: Publish-on-validation-error behavior is now opt-in for 3.6.x/3.7.x, and publish/bulk-publish endpoints honor the actual publish result. (0200a3bd19, 2e0f7f8add)

🐛 Fixes

• Scheduling — Cron: Empty Cron expressions no longer produce trigger payloads or fail validation, restoring support for unconfigured/disabled Cron triggers during workflow publishing. (42cbb5632a)
• Scheduling — Cron: Cron.ExecuteAsync now safely treats blank expressions as disabled when a Cron activity runs inside a workflow instead of throwing a CronFormatException. (3dba9e7293)
• Workflow API: Publish, bulk-publish, and workflow definition save responses now include validation warnings/errors so clients can show actionable feedback. (abccc89c73)

🧪 Tests

• Added coverage for configured application instance names, blank Cron trigger indexing/validation, blank Cron execution, and publish/import API validation behavior. (28d6786042, 42cbb5632a, 3dba9e7293, 0200a3bd19)

🔁 CI / Build

• Updated the package workflow base version to 3.6.3. (e8cc1d3c50)
• Skipped component tests in the package workflow to unblock the 3.6.3 package pipeline while preserving unit/integration coverage. (7eac7de695)
