Please see below for the new features added and issues that have been fixed.

### Enhancements

- Content: Now you can view published charts, notes, and dashboards that include R Custom Charts.
- Schedule: Now you can schedule contents that include AI Function steps.
- Schedule: Now you can schedule contents that include R Custom Charts.

### Bug Fixes

- Content: Updating the thumbnail image from the Settings dialog of a published note failed with a “Failed to update parameter settings” error.
- Content: Charts created with R code using d3.js (such as Sankey or Circular Chord Diagram) did not show up correctly on published notes and dashboards.
- Content: The green indicator lamp showing that another user had a project open remained permanently lit after the original user’s account was transferred to another user.
- Content: When sharing a published dashboard with users on the public plan, viewers who were given the “Can Update Share Setting” permission did not see the Share button.
- Content: When pasting a comma-separated list of email addresses into the share settings, users who already had access history were dropped from the registered list.
- Content: Data Catalog publish unnecessarily regenerated parquet files because step flags were not cleared, causing timeout errors on large data.
- Content: A UTF-8 BOM is now added to CSV files exported from interactive charts on published notes and dashboards, so that they open correctly in Excel without character corruption.
- Content: The ‘All’ option has been removed from the content type filter on the Insight Search page, and the default has been changed to Note.
- Data Source: BigQuery import with a service account returned null instead of raising an error when the query failed, making the failure invisible to the user.
- Admin: The horizontal scroll bar is now always visible on the user table in the Admin User page so that actions like Delete User are easier to discover.
