    ### **Platform improvements**

    <Card title="Platform Improvements" icon="wrench" iconType="duotone">
      <Tabs>
        <Tab title="Bug fixes">
          <Accordion title="Notable bug fixes">
            * **Real-time event delivery:** fixed a Redis connection leak in the Events Gateway. Blocking reads now run on a dedicated connection pool with Redis Cluster support, eliminating the gradual connection buildup that could previously require periodic Events Gateway restarts. New tuning options are available — see the [deployment guidelines](./deployment-guidelines-v5.9.3#configuration-changes).
            * **Build import:** fixed a race during multi-dependency imports where a transient database write conflict could silently drop a dependency's build, causing runtime errors on substitution tags and enumerations for that build. Large imports may take slightly longer as a result. {/* Internal: CORE-5026 (ZD-1313 #OTP), bd1616bc94 on release/5.9.x, first tag application-manager-v10.151.1 — IN via the B rebuild (Mircea 07-30). Same cherry-pick as the 5.1.11 fix (simple variant; main gets the complex one), so the slower-imports side effect (Alex K) applies on both lines. Verdict lock: shipped app-manager pin must be ≥10.151.1 — if fx shows lower at tag, PULL this bullet. */}
            * **Task management:** deleting a swimlane allocation rule now removes only the targeted rule instead of clearing other rules along with it, and duplicate rules are no longer created when Save is clicked twice. Task views also no longer reset when the same view is open from different workspaces. {/* Internal: RPT-4514 (ZD-1018) + RPT-6221 (536a33226b) + RPT-5757/RPT-6214 (2f889c28f7) */}
            * **Projects:** creating a project with the same name as a previously deleted project now returns a clear validation error instead of an internal server error.
            * **Designer stability:** fixed a freeze when opening Runtime after expanding a component's Permissions section, and a pending AI UI-generation draft no longer locks the process diagram read-only. {/* Internal: RPT-6444 + MT-3356 — designer commits on release/5.9.x post-10.260.7; pin-confirm at cut */}
            * **Date Picker:** the calendar now anchors correctly to its field above modals and while scrolling, and label, helper, and error text follow the themed padding. {/* Internal: RPT-6436 + RPT-6456 grouped (datepicker cluster, post-v10.262.0 → pin-confirm at cut); never name the reporting client (RPT-6456 summary carries a customer env) */}
            * **Workflows:** fixed a silent workflow freeze that could occur after a step exhausted its retries. {/* Internal: PLAT-1879 (3ef8adb59b, PE v10.162.2) — guard finish/fail SQL processing_status IN (NEW,STARTED) */}
            * **iOS renderer:** the form background is now applied correctly on native iOS, matching the Android behavior. UI Flows on iOS also gain support for the `additionalData` object.
              {/* TRIMMED per Bogdan 07-30 17:57 ("nu mentionam nimic"): react-native 10.266.0 retro-bump is version-rows-only, NO RN bullet. The grouped line ("React Native renderer: styling and parity fixes... multi-select stacking, slider sizing/tooltips, themed Date Picker icon, conditional styling, file-upload icon" = RPT-6413/6416/6417/6419/6420/6424/6425, all non-ZD) was briefly rendered and PULLED same day. Do not re-add. */} {/* Internal: RPT-6451 + RPT-6220 — CONFIRMED per Bogdan 07-30 14:16 ("daca ceva e done, inseamna ca sunt incluse in release-urile puse pe fixed version"; iOS 10.5.11 is the 5.9.3 pin per his 14:07 message). Do NOT ping Bogdan again on renderer containment — his fixVersion word is the confirmation; tags stay the silent cross-check. additionalData semantics: SDK docs touch-up owed separately (watchlist RPT-5062/6220, low priority) — verify exact mechanics there, not here. */}

            * **Media Library:** PDF assets in the list can now be opened in a new tab directly from the Media Library.
            * **Process start loading:** web renderers now keep the loading indicator visible until the first user task renders, matching the mobile SDK behavior. {/* Internal: RPT-6472, core-sdk 1e534062f0, first tag v10.265.2. CONTAINED under the B rebuild — designer pin goes to 10.265.6 per Mircea 07-30. Formality re-check via fx at tag. */}
