## V2026.05

### Diagnostic scripts

> The diagnostic file now includes internal InfluxDB performance metrics from the last 24 hours, providing deeper insight for troubleshooting and support analysis.\
> \
> Refer to [**Diagnostic Tools**](/manual/implementation/troubleshooting/platform-diagnostics-tools.md) section of the documentation.

### Top queries

> In rare cases, a query text may not be loaded into the platform. Datasentinel now automatically attempts to retrieve any missing query texts directly from the source PostgreSQL instance when displaying the [**Top Queries**](/manual/features/key-features/top-queries.md) dashboard

### Agent v3.9.2

> This release integrates [**Agent v3.9.2**](/manual/implementation/agent-usage/release-notes.md) which includes two fixes related to tag handling.

### :wrench: Fixes

> * **Full Report generation**\
>   Generating a [**Report** ](/manual/features/key-features/reporting.md)could occasionally fail with a `list index out of range` error.
> * **Top Queries export**\
>   Exporting [**Top Queries**](/manual/features/key-features/top-queries.md) data in JSON format did not honor the **per execution** flag.\
>   Resolved an error that occurred when exporting data in CSV format.
>   {% endupdate %}
