Release Notes - **Release date: February 1st, 2021** ### Improvements * We updated the [SAP HANA](https://docs.mendix.com/refguide8/saphana) driver to 2.7.9. * We now allow JDBC URL options to set data source properties for SAP HANA. * We disabled the `transactionalLobs` option in SAP HANA. * We improved the performance of the `Core.getActiveSession(userName)` method. ### Fixes * We fixed a runtime issue in [Call REST](https://docs.mendix.com/refguide8/call-rest-action) activities when calling endpoints that keep the connection alive. The issue occurred in Mendix Cloud v4- and AWS-hosted apps, because those environments sever connections after 6 minutes. Setting `http.client.CleanupAfterSeconds` to `355` fixes that issue, so now we use that as the default value. (Tickets 110860, 111317, 111881, 112067, 112073, 113401, 113920) * We fixed a runtime issue in Call REST activities where trace logging changed the contents of responses. (Tickets 112613, 113750, 114499, 114516) * We fixed an issue where conditional visibility on a pluggable widget (or a widget inside a pluggable widget) did not work correctly if the pluggable widget was inside a snippet. (Ticket 113612) * We fixed an error in the runtime where a widget retrieved over 1000 records. (Ticket 108750) * We fixed an issue where calling a microflow from an [offline-first](https://docs.mendix.com/refguide8/offline-first) application triggered an unnecessary reload of data sources on the opened pages. (Ticket 114660) * We fixed an issue in native mobile apps where a focused text input was hidden behind the keyboard on Android devices. Make sure to also update your versions of the [Make It Native app](https://docs.mendix.com/releasenotes/mobile/make-it-native-app) and [Native Builder](https://docs.mendix.com/releasenotes/mobile/native-builder). (Ticket 113397) * We fixed an issue where errors occurred when performing certain operations (for example, moving documents) when certain custom widgets existed in your app project. ### Known Issues * When you update a [consumed OData service](https://docs.mendix.com/refguide/consumed-odata-service) with a new version from [Mendix Data Hub](https://docs.mendix.com/data-hub/index) but close the document without saving, the blue arrow icon will no longer be shown to notify you about the available update for that service. * Workaround: Closing your app project and opening it again fixes this issue.
