# Tenzir Node v4.13.1

## 🐞 Bug Fixes

### Relax `transform_columns`

May 13, 2024 · [@dominiklohmann](https://github.com/dominiklohmann) · [#4215](https://github.com/tenzir/tenzir/pull/4215)

The `enrich`, `drop`, `extend`, `replace`, and `deduplicate` operators failed for empty input events. This no longer happens.

### Remove stream managers when decommissioning partitions

May 13, 2024 · [@dominiklohmann](https://github.com/dominiklohmann) · [#4214](https://github.com/tenzir/tenzir/pull/4214)

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.

### Improve `slice` with positive begin and negative end

May 13, 2024 · [@dominiklohmann](https://github.com/dominiklohmann) · [#4210](https://github.com/tenzir/tenzir/pull/4210)

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.

### PRs 4212-satta

May 12, 2024 · [@satta](https://github.com/satta) · [#4212](https://github.com/tenzir/tenzir/pull/4212)

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.
