# Tenzir Node v4.10.0 ## 馃殌 Features ### Implement multi-field lookups for context implementations Mar 11, 2024 路 [@Dakostu](https://github.com/Dakostu) 路 [#3968](https://github.com/tenzir/tenzir/pull/3968) The `enrich` and `lookup` operators now support type extractors, concepts, and comma-separated lists of fields as arguments to `--field`. ### Add configurable pipelines Mar 11, 2024 路 [@tobim](https://github.com/tobim) 路 [#4006](https://github.com/tenzir/tenzir/pull/4006) We made it possible to set pipelines declaratively in the `tenzir.yaml` configuration file. ### Fix partial specialization of S3 configuration in URL Mar 11, 2024 路 [@dominiklohmann](https://github.com/dominiklohmann) 路 [#4001](https://github.com/tenzir/tenzir/pull/4001) S3 access and secret keys can now be specified in the S3 plugin鈥檚 configuration file. ### Introduce multi-arch Docker images Mar 6, 2024 路 [@dominiklohmann](https://github.com/dominiklohmann) 路 [#3989](https://github.com/tenzir/tenzir/pull/3989) The `tenzir/tenzir` and `tenzir/tenzir-node` Docker images now run natively on arm64 in addition to amd64. ### Allow using `and`, `or`, and `not` in expressions Mar 5, 2024 路 [@dominiklohmann](https://github.com/dominiklohmann) 路 [#3993](https://github.com/tenzir/tenzir/pull/3993) The `where` operator now supports using `and`, `or`, and `not` as alternatives to `&&`, `||`, and `!` in expressions. ## 馃敡 Changes ### Improve metrics collection Feb 26, 2024 路 [@dominiklohmann](https://github.com/dominiklohmann) 路 [#3982](https://github.com/tenzir/tenzir/pull/3982) Nodes now collect CPU, disk, memory, and process metrics every second instead of every ten seconds, improving the usability of metrics with the `chart` operator. Memory metrics now work as expected on macOS. ### Introduce the `no-location-overrides` option Feb 23, 2024 路 [@dominiklohmann](https://github.com/dominiklohmann) 路 [#3978](https://github.com/tenzir/tenzir/pull/3978) We鈥檝e replaced the `tenzir.allow-unsafe-pipelines` option with the `tenzir.no-location-overrides` option with an inverted default. The new option is a less confusing default for new users and more accurately describes what the option does, namely preventing operator locations to be overriden. ## 馃悶 Bug Fixes ### Fix panic on parsing invalid syslog messages Mar 11, 2024 路 [@eliaskosunen](https://github.com/eliaskosunen) 路 [#4012](https://github.com/tenzir/tenzir/pull/4012) Parsing an invalid syslog message (using the schema `syslog.unknown`) no longer causes a crash. ### Fix crash in `sigma` operator for non-existent file Mar 11, 2024 路 [@dominiklohmann](https://github.com/dominiklohmann) 路 [#4010](https://github.com/tenzir/tenzir/pull/4010) The `sigma` operator sometimes crashed when pointed to a non-existent file or directory. This no longer happens. ### Fix partial specialization of S3 configuration in URL Mar 11, 2024 路 [@dominiklohmann](https://github.com/dominiklohmann) 路 [#4001](https://github.com/tenzir/tenzir/pull/4001) The S3 connector no longer ignores the default credentials provider for the current user when any arguments are specified in the URI explicitly. ### Prevent tcp socket inheritance to child processes Mar 8, 2024 路 [@tobim](https://github.com/tobim) 路 [#3998](https://github.com/tenzir/tenzir/pull/3998) We fixed a problem with the TCP connector that caused pipeline restarts on the same port to fail if running `shell` or `python` operators were present. ### Make `remote python` work Mar 5, 2024 路 [@dominiklohmann](https://github.com/dominiklohmann) 路 [#3999](https://github.com/tenzir/tenzir/pull/3999) The `python` operator now works with when using the `remote` location override. ### Fix a TOCTOU bug that caused the index to fail Mar 4, 2024 路 [@dominiklohmann](https://github.com/dominiklohmann) 路 [#3994](https://github.com/tenzir/tenzir/pull/3994) Tenzir nodes sometimes failed when trying to canonicalize file system paths before opening them when the disk-monitor or compaction rotated them out. This is now handled gracefully. ### Count nulls and absent values in `top` and `rare` Feb 29, 2024 路 [@dominiklohmann](https://github.com/dominiklohmann) 路 [#3990](https://github.com/tenzir/tenzir/pull/3990) The `top` and `rare` operators now correctly count null and absent values.
