+### Improvements
+
+- We introduced a new log node named **SystemTask** for logging system management actions.
+- We improved the performance of runtime statistics collection.
+- We improved the performance of the **Best Practice Recommender**. It now runs faster while using less memory.
+- We improved the performance of [document](/developerportal/general/documents/) operations (**add**, **rename**, **delete**, and more) in the **App Explorer**.
+- We added batching to the `session keep-alive` and `last action execution update` maintenance tasks. The batch size can be changed using the `SessionKeepAliveUpdateBatchSize` and `LastActionExecutionUpdateBatchSize` runtime settings.
+- We now support tags for the `tcpjsonlines` log subscriber. These can be configured with the `tags` property in the configuration of the log subscriber.
+- For the `tcpjsonlines` log subscriber we now include tracing information if `includeTracingInformation` is set to `true` when creating the log subscriber. Additionally, `traceIdAttribute` and `spanIdAttribute` can be passed to configure the attributes of the trace and span IDs in the output JSON log.
+
+### Fixes
+
+- We fixed an issue where sorting by column would not work after using the text search on a grid. (Ticket 266400)
+- We fixed an issue where Studio Pro could crash when importing a font for an [icon collection](/refguide/icon-collection/). (Ticket 266772)
+- We fixed an issue where an incorrectly configured [placeholder text](/refguide/text-box/#placeholder-text) did not show a consistency error and could result in an error during deployment. (Ticket 266923) 
+- We resolved an issue where passwords, when having write access for the password attribute, could be modified directly through the `synchronize_objects` API.
+- We fixed an issue that was causing excluded modules to be included in **main.scss** when generating layered CSS.
+- We fixed an issue where pasting a view entity together with its associated persistent entity would cause a freeze and an Oops pop-up window.
+- In the logic editors, we fixed a bug that causes Maia Explain for Microflows to crash.
+- We fixed an issue where an Oops pop-up window was displayed when **Edit** > **Find** returned new JSON structure documents.
+- We fixed an issue in consumed REST services in Studio Pro where sending a request to a URL that contained invalid characters would result in an Oops pop-up window.
+- We now correctly set the log node name as the "node" attribute and the exception cause as the "cause" attribute for the OpenTelemetry log subscriber.
+- We fixed an issue where calling the `get_license_information` while using a SALT license would cause an error.
+
+### Breaking Changes
+
+- Curly braces in a [placeholder text](/refguide/text-box/#placeholder-text) (for example, `{Name}`) must now be escaped with an extra opening curly brace (for example, `{{Name}`) to prevent the text from being incorrectly interpreted as a placeholder expression.
