All other enhancements, not related to specific disciplines, are described in the [IMS Planform (General)](/docs/ims-platform-general-release-20241) Release Notes. --- ## LOPA Improvements ### LOPA Study Tab renamed: Additional Information Tab [IMSFB-39584](https://cenosco.myjetbrains.com/youtrack/issue/IMSFB-39584) The old LOPA Study tab was renamed to Additional Information and moved to the bottom of the list. The new Study tab will appear only if the LOPA has Study data. ![](https://cdn.document360.io/e492a0e0-a4ba-4aca-8fc6-76b95f91fdf3/Images/Documentation/pic 1-O3VY4ACJ.png?sv=2026-02-06&spr=https&st=2026-10-28T16%3A49%3A57Z&se=2026-10-28T17%3A49%3A57Z&sr=c&sp=r&sig=5rAdU5SHeRnbGmUdpXDZ6yAwi4mNgX95lPoxjlVSJlE%3D) > [!NOTE] > User Instructions > > To learn more about the LOPA Tabs, see: [LOPA Details Page - Overview](/docs/lopa-details-layout#side-tabs). ## SIF Analysis Improvements ### Safety Critical Element (SCE) Reviewed check added [IMSFB-43532](https://cenosco.myjetbrains.com/youtrack/issue/IMSFB-43532) We have added a Safety Critical Element Reviewed checkbox below the Safety critical override checkbox on the SIF Analysis Details Page(General and Design Tabs). This needs to be checked when the warning "Require Process Hazard Assessment" (red text next to the Safety Critical Element (SCE) field) shows. When Safety Critical Element Reviewed is checked, the warning will be removed. The checkbox is enabled only when both Safety Critical Element is true (checked) and the warning is present. When the calculation for the SCE is retriggered the Safety Critical Element Reviewed checkbox will be unchecked again. If Safety Critical Element is checked because of the Safety critical override then the warning would not be shown and the Safety Critical Element Reviewed checkbox will be disabled. A new validation rule was also added for Approval: The SIF Analysis cannot be Approved when the warning shows and Safety Critical Element Reviewed is not checked. A warning will also show in the approval panel: "Safety Critical Element not reviewed". ![](https://cdn.document360.io/e492a0e0-a4ba-4aca-8fc6-76b95f91fdf3/Images/Documentation/pic 1-4M10UA18.png?sv=2026-02-06&spr=https&st=2026-10-28T16%3A49%3A57Z&se=2026-10-28T17%3A49%3A57Z&sr=c&sp=r&sig=5rAdU5SHeRnbGmUdpXDZ6yAwi4mNgX95lPoxjlVSJlE%3D) > [!NOTE] > User Instructions > > To learn more about the Safety Critical Element checks, see: [SIF Analysis General Tab](/v414/docs/general-tab). ### Approval Dialog now Collapsible [IMSFB-39456](https://cenosco.myjetbrains.com/youtrack/issue/IMSFB-39456) The Approval dialog on the SIF Analysis Details Page can now be collapsed or uncollapsed with the *Checkmark* button, giving more space for the subsystem data. ![](https://cdn.document360.io/e492a0e0-a4ba-4aca-8fc6-76b95f91fdf3/Images/Documentation/pic 1-4ODP72BU.png?sv=2026-02-06&spr=https&st=2026-10-28T16%3A49%3A57Z&se=2026-10-28T17%3A49%3A57Z&sr=c&sp=r&sig=5rAdU5SHeRnbGmUdpXDZ6yAwi4mNgX95lPoxjlVSJlE%3D) > [!NOTE] > User Instructions > > To learn more about Approving SIF Analyses, see: [Approving the SIF Design](/v414/docs/approving-the-sif-design). ### Batch PFD Calculations [IMSFB-43275](https://cenosco.myjetbrains.com/youtrack/issue/IMSFB-43275) Batch calculations can now be performed on multiple SIF Analyses. The *Batch calculation* button is available in the SIF Analysis Main Screen toolbar. The Batch calculation dialog will show how many of the selected Analyses will be calculated. Only SIF Analyses in Draft will be calculated. The dialog also contains a **Show list** button that can be used to see detailed list of the SIF Analyses. After calculation the **Show list** button can be used to see the reasons for the not calculated SIFs. ![](https://cdn.document360.io/e492a0e0-a4ba-4aca-8fc6-76b95f91fdf3/Images/Documentation/pic 1-YQ4FOPZB.png?sv=2026-02-06&spr=https&st=2026-10-28T16%3A49%3A57Z&se=2026-10-28T17%3A49%3A57Z&sr=c&sp=r&sig=5rAdU5SHeRnbGmUdpXDZ6yAwi4mNgX95lPoxjlVSJlE%3D) ![](https://cdn.document360.io/e492a0e0-a4ba-4aca-8fc6-76b95f91fdf3/Images/Documentation/pic 1-Q75ZZDUP.png?sv=2026-02-06&spr=https&st=2026-10-28T16%3A49%3A57Z&se=2026-10-28T17%3A49%3A57Z&sr=c&sp=r&sig=5rAdU5SHeRnbGmUdpXDZ6yAwi4mNgX95lPoxjlVSJlE%3D) > [!NOTE] > User Instructions > > To learn more about the SIF Analysis Batch Calculations, see: [SIF Analysis Main Screen](/docs/listing-sif-analyses-the-overview-grid#batch-pfd-calculations). ### Event History Added [IMSFB-44216](https://cenosco.myjetbrains.com/youtrack/issue/IMSFB-44216) The SIF Analysis now includes an Event History.
