Vast Versions Save

This patch release contains the following bug fixes and improvements over Tenzir v4.13:

• The slice operator no longer waits for all input to arrive when used with a positive begin and a negative (or missing) end value, which rendered it unusable with infinite inputs. Instead, the operator now yields results earlier.
• The amqp connector now properly signals more errors caused, for example, by networking issues. This enables pipelines using this connector to trigger their retry behavior.
• The node's CPU usage increased ever so slightly with every persisted partition, eventually causing imports and exports to get stuck. This no longer happens.
• The enrich, drop, extend, replace, and deduplicate operators failed for empty input events. This no longer happens.

We're delighted to announce Tenzir v4.13, a release focusing on stability and incremental improvements.

This patch release contains the following bug fixes and improvements over Tenzir v4.12:

Tenzir v4.12.2

• The python operator now checks for syntax errors on operator startup.
• Transformations or sinks used with the every operator modifier did not shut down correctly when exhausting their input. This now works as expected.
• We fixed a bug that prevented restarts of pipelines containing a listening connector under specific circumstances.
• The retry delay now works for pipelines that fail during startup.
• The chart operator failed to render a chart when the y-axis was not specified explicitly and the events contained more than two top-level fields. This no longer happens.
• We accidentally removed the implicit read json from from tcp in Tenzir v4.12. The short form now works as expected again.
• The chart operator now accepts the flags --x-axis-type and --y-axis-type for bar, line, and area charts, with the possible values being log and linear, with linear as the default value. Setting these flags defines the scale (logarithmic or linear) on the Tenzir App chart visualization.

Tenzir v4.12.1

• We fixed a misconfiguration that caused the publish and subscribe operators not to be available in the statically linked Linux builds.
• We fixed a crash on startup when selectively enabling or disabling plugins when at least two plugins with dependent plugins were disabled.

We are thrilled to announce Tenzir v4.12, a feature-packed release introducing numerous enhancements. Notable additions include list unrolling, event deduplication, and the deployment of advanced pipeline architectures with publish-subscribe. We've also added a download button, extended support for UDP, and implemented many other refinements to improve your experience.
