Release Notes - **Release date: October 30, 2025** ### Improvements * We added support for Oracle 23. * We now avoid resetting the failed login count during login when it is already zero. (Ticket 260858) * We increased the default size of popup dialogs that contain expression fields to allow for easier editing of the expressions. * We have optimized the page exports for the React and Native clients. This can decrease the exported page size by up to 35%, making the resulting bundle a lot smaller. ### Fixes * We fixed a non-fatal crash in the studio pro installer when the installer is checking if the dotnet version is already installed or not. (Ticket 253218) * We fixed an issue in the Studio Pro XPath constraint parser that incorrectly allowed associations and associated objects to be compared to Boolean values or empty, while that was not supported on the runtime. The following constructs will now lead to consistency errors: * `[MyModule.MyAssociation = false()]` * `[MyModule.MyAssociation = empty]` * `[MyModule.MyAssociation/MyModule.MyEntity = false()]` * `[MyModule.MyAssociation/MyModule.MyEntity = empty]` (Tickets 254830 and 258029) * We fixed an issue in the Domain Model Editor where navigating to a specific OQL view entity with a consistency error from the Error pane would result in an error if the "Show View Entity" option was disabled. (Ticket 256365) * We fixed an issue where trying to delete a huge number (millions) of anonymous sessions during startup would cause out of memory errors. We now delete sessions and anonymous users in batches to avoid this problem. (Ticket 257047) * We fixed an issue where the React client would not get bundled when deploying for Eclipse. (Ticket 258470) * We fixed an issue with Offline PWAs when using the React client where changes to the application would not be shown to the user without clearing the cache. (Ticket 260673) * We fixed a "no such column" error when synchronizing a file or image derived entity which itself is derived by another entity with an offline synchronization mode. (Ticket 261700) * We fixed an issue in the Studio Pro XPath constraint parser with the treatment of `true` and `false` . These are now treated the same as their function equivalents (`true()` and `false()` respectively). * We fixed a memory leak that occurred when editing an action of a Microflow. * We fixed an issue in offline apps that could result in data validations of microflow calls not being properly handled. * We fixed an issue preventing opening apps passed as startup arguments for Studio Pro in MacOS. * We fixed an issue where a drop-down list in a Reference Selector reopened automatically after closing. * We fixed an issue where duplicate responsive navigation profiles could not be removed. * We fixed an issue with using a dash `-` in the *Organization Name* of a pluggable widget. * We fixed an issue where building an app in a different culture would result in decimal numbers changing their decimal separator.
