## :label: v2025.11

*<mark style="color:blue;">Nov 12, 2025</mark>*

### PostgreSQL 18

> Fully compatible with the [latest PostgreSQL 18 release](https://www.postgresql.org/docs/18/index.html)

### Limit configuration for Agentless connections

> When connecting to PostgreSQL clusters using the Agentless method, you can now define limits for the maximum number of monitored tables and queries per cluster.\
> This capability was previously available only for [clusters monitored by local agents](https://docs.datasentinel.io/manual/implementation/agent-usage/cli#change-table-monitoring-limit).
>
> Refer to [Agentless Monitoring](https://docs.datasentinel.io/manual/features/other-features/agentless-monitoring) section for more details

### Messaging&#x20;

> To enhance clarity, intrusive **"no data found"** messages have been removed or improved:
>
> * In the [**Active Session History**](https://docs.datasentinel.io/manual/features/key-features/session-history) chart, the message now appears as a subtle header note: \
>   \&#xNAN;**"No active sessions detected"** when no metrics are available.
> * In the [**Top Queries**](https://docs.datasentinel.io/manual/features/key-features/top-queries) dashboard, the message has been updated to: \
>   \&#xNAN;**"No metrics available for the selected time range"**, providing clearer context for users.

### Diagnostic Scripts

> Two diagnostic scripts have been added to help identify and troubleshoot platform issues more efficiently.\
> For details, see the [**Diagnostic Tools**](https://docs.datasentinel.io/manual/implementation/troubleshooting/platform-diagnostics-tools) section of the documentation.

### Libraries

> Updated third-party libraries for better performance, security, and compatibility

### API

> A new  column has been added to the response of the [**Instance Information API**](https://docs.datasentinel.io/manual/implementation/platform-usage/api-reference/workload#informations)
>
> * "**last\_collection\_time**":  Timestamp of the most recent data collection for this instance.

### Agent v3.8.0

> Refer to the [Agent Release Notes](https://docs.datasentinel.io/manual/implementation/agent-usage/release-notes)

#### :wrench: Fixes

> * **Solaris Compatibility for `system_stats` extension**\
>   Resolved an issue where the [system\_stats](https://github.com/EnterpriseDB/system_stats) extension running on Solaris systems was missing certain metric fields. \
>   The [Agentless feature](https://docs.datasentinel.io/manual/features/other-features/agentless-monitoring) now embeds the updated agent version to ensure complete and accurate metric collection.
> * **Reliable Patch Application**\
>   The patch script now writes its log file to **`/tmp`** instead of the current directory. This prevents failures when the user lacks write permissions, ensuring backend and dispatcher services restart properly with the new binaries.
> * **Faster Instance Deletion**\
>   When deleting an instance from Datasentinel UI, only the most recent **status** metrics are now removed instead of the entire history. This speeds up the deletion process.
> * **Deduplication**\
>   Resolved an issue where recent changes to tags caused duplicate instance entries in [**Instance Information API**](https://docs.datasentinel.io/manual/implementation/platform-usage/api-reference/workload#informations). Duplicates are now automatically removed by keeping only the most recent `last_collection_time`.

## :label: v2025.07

### :wrench: Fixes

> **LDAP user updates**\
> Editing an [LDAP-authenticated account](https://docs.datasentinel.io/manual/implementation/platform-usage/configuration/ldap) no longer clears its “LDAP” flag; the user now retains that status and remains visible in the [Users](https://docs.datasentinel.io/manual/implementation/platform-usage/configuration/users-and-roles) dashboard after an update.

## :label: v2025.06

*<mark style="color:blue;">Jun 9, 2025</mark>*

>
> * "**type**":  The instance type — either `"primary"` or `"replica"`.
> * "**port**": The listening port of the instance ([**requires Agent version 3.7+**](https://docs.datasentinel.io/manual/implementation/agent-usage/release-notes) if using local agents).
> * "**databases**": Total number of databases in the instance.
> * "**size**": Total size of the cluster in bytes.

### Agent v3.7.0

> Refer to the [Agent Release Notes](https://docs.datasentinel.io/manual/implementation/agent-usage/release-notes)

### :wrench: Fixes

> * In rare cases, the log file `backend_to_influx.log` related to InfluxDB write errors could grow excessively large. Its size is now limited to **256 MB**, with a maximum of **one backup file**. \
>   Refer to the [Log Files](https://docs.datasentinel.io/manual/implementation/platform-usage/log-files) section.
> * Resolved an issue with dynamic filters on the dashboard that affected the display of [registered users](https://docs.datasentinel.io/manual/implementation/platform-usage/configuration/users-and-roles).
