# Patch 6.2.0.4
Tellius 6.2.0.4 introduces the Dremio data connector, Kaiya conversation pinning, Kaiya Apps sharing with multi-BV support, and two targeted performance optimizations for Vizpad filter loading and custom calendar initialization. This patch also delivers significant attention to Vizpad refinement — particularly around filter behavior, custom views, chart rendering, drill-down, export, and consistency between classic and modern views.
## 📈 Enhancements
#### Dremio Data Connector
Tellius now supports Dremio as a data source. The Dremio connector is available under **Data → Connect,** enabling organizations running Dremio data lakes to connect directly to Tellius.
#### Pin and Favorite Kaiya Conversations
Users can now mark favorite Kaiya conversations for quick access. Conversations marked favorite appear at the top of the conversation list, making it easier to access.
#### Sharing for Kaiya Apps
Kaiya Apps can now be shared with other users and groups. App owners can manage sharing permissions, giving teams access to published analytical applications without requiring each user to create their own.
#### Kaiya Apps: **Refresh Scheduling, Refresh History, and Full-Screen Mode**
Kaiya Apps now expose data refresh controls directly in the app toolbar and let you configure refresh schedules conversationally inside the app.
A new refresh menu in the app toolbar surfaces three actions:
* **Refresh Now:** Triggers an immediate, on-demand refresh against the underlying Business View. The app remains viewable during the refresh, displaying the last completed snapshot.
* **Schedule Refresh:** Opens the scheduling configuration to set up recurring automatic refreshes (frequency, date, and time preferences).
* **Refresh History:** Shows the full history of past refreshes for the app, including timestamps and status.
In addition to the toolbar menu, refresh schedules can now be configured directly in the Kaiya App conversationally. Tell Kaiya something like *"Refresh this app every Monday at 6 a.m."* and the schedule is created and applied without leaving the conversation. Existing schedules can be modified the same way.
A new full-screen control in the toolbar opens the app in an expanded view in a new tab, giving the app the full viewport.
#### Visual indicators for switch metric
When a user switches a metric on a chart, a badge displaying the active metric name now appears in the chart header. This makes the currently selected metric visible at a glance, especially when multiple switches have happened during a session.
#### Cross-BV column awareness for multi-BV Vizpads
For Vizpads built on multiple Business Views, columns that are common across BVs are now visually indicated in the switch metric configuration. Vizpad authors can mark these common columns as active for switching and designate a default, so users running the Vizpad can switch metrics across BVs without leaving the chart.
#### Pinned Filter Performance: Lazy Loading
Pinned dropdown filters (multi-select, single-select, pulldown) now load their option lists only when the dropdown is opened, rather than loading all filter values on Vizpad open or tab switch. For Vizpads with many pinned filters, this reduces initial load time and defers data retrieval to the moment of interaction. The expand/collapse responsiveness for pinned filter accordions has also been improved for high-volume datasets.
#### Custom Calendar Dynamic Loading
Custom calendars are now loaded on demand based on whether they are actively used by a Business View, rather than loading all calendars into memory at startup. Only the ISO calendar is loaded by default. This reduces memory consumption and improves initialization time, particularly in environments with many custom calendar definitions.
#### **Section-level Switch Metrics and Time Resolution**
Each Vizpad section now supports its own independent switch metric configuration, in addition to the section-level filters that were already available. Switching a metric in one section does not affect the metric selection in other sections, making it possible to compare different metrics side-by-side within the same Vizpad.
A new Vizpad-level time resolution control also sets the date granularity (for example, monthly, quarterly, or yearly) for every chart in the Vizpad in one place. Section-level time resolution settings always take precedence. Any granularity explicitly configured on a specific section continues to apply, and the Vizpad-level control only governs charts that don't have their own setting. This gives Vizpad authors a single control to roll out a default granularity across a dashboard while preserving any per-chart overrides.
#### In-Product Help Page Redesign
The in-product Help page (under Settings → Help) has been redesigned with an updated layout, a search bar, and four action tiles: Chat with us, Create a ticket, Share feedback, and Help guide. Previously outdated links have been replaced with current resources.
#### Consistent Markdown Font Sizes
Markdown content rendered across the platform now uses font sizes that are consistent with other application components, ensuring a uniform visual experience when markdown is used in text visualizations, tooltips, and documentation surfaces.
#### Format Menu Panel Cleanup
The mini preview overlay that appeared when hovering over options in the Format menu panel has been removed. The descriptions remain and provide sufficient context for each formatting option without the redundant preview.
#### Export Pipeline Improvements
Improved concurrency handling and correlation logging in the Vizpad export pipeline. These changes improve export reliability for PPT, Excel, and CSV across complex Vizpads.
## 🛠️ Minor Fixes
#### Kaiya
1. Improved Kaiya analysis accuracy, data label handling, sort behavior, and drill interactions for more consistent chart generation in multi-turn conversations.
2. Addressed an issue where Explainable AI visualizations were not rendering on the Model page (under Predict → Models). The visualizations now display correctly with proper translations.
3. Resolved an issue where feature importance graphs displayed index numbers in tooltips rather than the actual column names.
4. Addressed inconsistent message ordering in Kaiya App chat. Messages now appear in the correct chronological sequence.
#### Vizpads - Filters
5. Ensured that null values appear correctly in visualization filter dropdown lists.
6. Resolved an issue where pinned filter changes were not reflected after unpinning a filter in bulk mode.
7. Improved filter pill display for charts added via Search, ensuring pills render correctly regardless of chart name length.
8. Refined the filter dropdown experience when chart names are long, preventing visual overlap with adjacent elements.
9. Addressed an issue where null filter values could disappear when selecting other values in the same filter.
10. Resolved an issue where interacting with date filters could produce an unexpected navigation state.
11. Improved date filter initialization so that filter values load only when interacted with, rather than on initial Vizpad open or slider adjustment.
12. Ensured that filters applied via personalization retain their selected values when entering and exiting edit mode.
13. Resolved an issue where editing or updating a date filter in view or edit mode could remove global filters from the Vizpad.

40. Ensured that the "Next Data" pagination icon is correctly disabled when no additional data is available.
41. Improved axis formatting for Growth charts, ensuring width and style settings apply as configured.
42. Resolved an issue where the anomalies toggle in line charts did not respond when Vizpad-level anomaly settings were active. The toggle now correctly enables and disables from chart advanced settings.
43. Addressed an issue where removing an absolute change column also removed other related percentage change columns for the same source column.
44. Ensured that filters are retained when switching between chart buckets. The "Add Filter" option is now also available for calculated columns.
