Release Notes - **Release date: June 5, 2025** ### Improvements * When importing a module, widget, solution package or when starting a new app from a template, we now prevent the package from unpacking content to undesired directories. The user can still choose to extract the rest of the package. * We improved accessibility in dialog boxes by allowing the keyboard to reach the **Close** button. ### Fixes * We fixed the behavior of the `urlEncode` and `urlDecode` functions in the client to align with the runtime. This means that spaces are now correctly encoded as `%20` instead of `+`. `urlDecode` still supports decoding strings containing `+` to ensure backwards compatibility with strings encoded in previous versions. (Ticket 245510) * We fixed an issue in the domain model editor, where an unexpected exception closed Studio Pro instead of showing an exception in a dialog. * We fixed an issue where Studio Pro would showed an exception while checking the consistency of external attributes, associations, and enumerations. * We fixed an issue where some task queue tasks remained in the *Running* state when a clustered application was restarted while optimistic locking was also enabled. (Ticket 239838) * We fixed the date format preview in Studio Pro to be consistent with the actual date formatting behaviour in the runtime and client. ### Breaking Changes * We updated the date formatting in the client to be consistent with the runtime in supporting genitive and abbreviated month names. See the table below for the changes between the old and new formatting. The runtime formatting has not changed and is equal to the new client behavior. | Token | Old | New |-------|-----------|-------- | MMM | genitive | genitive abbreviated | MMMM | genitive | genitive | LLL | genitive | standalone abbreviated | LLLL | genitive | standalone ### Known Issues * A finished parallel split path that is removed from a running workflow instance wrongly leads to a versioning conflict. Please note that "path" was called "branch" in earlier versions. * Fixed in [10.17.0](https://docs.mendix.com/releasenotes/studio-pro/10.17/#fix-finished-parallel-split). * Importing a module containing workflows makes all running workflow instances incompatible. (Ticket 234084) * Fixed in [10.21.0](https://docs.mendix.com/releasenotes/studio-pro/10.21/#fix-workflow-instances). * There is a positioning error in the logic editors when you are dragging a large element, such as a loop, into a sequence flow, it overlaps with the existing elements. * Fixed in [10.12.12](https://docs.mendix.com/releasenotes/studio-pro/10.12/#fix-positioning-error) and in [10.14.0](https://docs.mendix.com/releasenotes/studio-pro/10.14/#fix-positioning-error). * Line endings in CSS files are not being handled properly, so when using [Revert All Changes](https://docs.mendix.com/refguide/using-version-control-in-studio-pro/) or performing other version-control operations, CSS files appear in the [Changes on Disk](https://docs.mendix.com/refguide/version-control-menu/#show-changes) dialog box. * Fixed in [10.18.0](https://docs.mendix.com/releasenotes/studio-pro/10.18/#fix-line-endings).
