# Tenzir Node v5.13.1

This release adds a new Azure Blob Storage operator with account key authentication and improves Google Security Operations retry handling. It also contains various small fixes and improvements.

## 🚀 Features

### `from_azure_blob_storage` operator

Aug 26, 2025 · [@raxyte](https://github.com/raxyte) · [#5429](https://github.com/tenzir/tenzir/pull/5429)

The new `from_azure_blob_storage` operator works similarly to `from_file` but supports additional Azure Blob Storage specific options.

For example, you can set the `account_key`:

```tql
from_azure_blob_storage "abfs://container/data/*.csv", account_key="your-account-key"
```

### Dynamic `namespace` and retry logic for `to_google_secops`

Aug 26, 2025 · [@raxyte](https://github.com/raxyte) · [#5446](https://github.com/tenzir/tenzir/pull/5446)

The `to_google_secops` operator now retries requests which fail with a `5XX` or a `429` status code. Additionally, the `namespace` option of the operator now supports all expressions that evaluate to a `string`.

## 🐞 Bug Fixes

### Misleading `from_file remove=true` warning

Aug 28, 2025 · [@jachris](https://github.com/jachris) · [#5438](https://github.com/tenzir/tenzir/pull/5438)

The `from_file` operator emits a warning when using `remove=true` if the file could not be removed. When deleting the last file inside an S3 directory, we keep that directory around by inserting a zero-sized object. However, this failed when the necessary `PutObject` permissions were not granted, thus emitting a warning even though the file was removed successfully. For this specific case, we thus no longer emit a warning. Other issues during file deletion are still reported.

### Timezone troubles from `parse_time()`

Aug 25, 2025 · [@raxyte](https://github.com/raxyte) · [#5435](https://github.com/tenzir/tenzir/pull/5435)

We fixed assertion failures when using the `parse_time` function with the `%z` or `%Z` specifiers.

### Buffering in the `fork` operator

Aug 22, 2025 · [@raxyte](https://github.com/raxyte) · [#5436](https://github.com/tenzir/tenzir/pull/5436)

We fixed an issue in the `fork` operator where the last event would get stuck.

### Fixed crash when writing out enumerations

Aug 21, 2025 · [@IyeOnline](https://github.com/IyeOnline) · [#5434](https://github.com/tenzir/tenzir/pull/5434)

We fixed a rare crash that could occur when writing/printing enumeration values in various formats.
