+The `HomeLeftNavItem.Collections` enum value is now available in the Visual Embed SDK. Embed developers can include *Collections* as a selectable navigation option in the embedded left navigation panel for full application embeds. When enabled, end users of the embedded application can navigate to *Collections* from the left navigation panel.

 This changelog lists the features and enhancements introduced in REST API v2.0. For information about new features and enhancements available for embedded analytics, see xref:whats-new.adoc[What's New].
 
+== Version 26.9.0.cl, September 2026
+
+    === Answer Export API enhancements — General Availability
+
+    // SOURCE: SCAL-306069
+
+    The `POST /api/rest/2.0/report/answer` endpoint is generally available from 26.9.0.cl. The `isAnswerExportV2Enabled` flag is enabled by default on all ThoughtSpot Cloud instances. The following enhancements are included in this release:
+
+    Pinned Answer export::
+    Pass `viz_guid` to export a pinned Answer (a visualization on a Liveboard) directly. Liveboard-level filters and runtime overrides are applied automatically. The `metadata_identifier` must be the parent Liveboard GUID or name.
+
+    Personalized View support::
+    Pass `personalised_view_identifier` to export data from a specific Personalized View of a Liveboard.
+
+    Spotter Answer export::
+    XLSX and PDF export formats are now supported for Spotter-generated (ad hoc) Answers, in addition to CSV and PNG.
+
+    Custom PNG dimensions::
+    Use `x_resolution` and `y_resolution` parameters to specify custom pixel dimensions for PNG exports. Accepted range: 600–3840 px per axis. Default: 2254 × 1588.
+
+    Display scaling::
+    Use `scaling_factor` (range: 80–400) to adjust the relative size of chart elements in a PNG export without cropping the image.
+
+    Dynamic file naming::
+    Exported files are automatically named based on the Answer title with the correct file extension (`.png`, `.pdf`, `.csv`, `.xlsx`) appended.
+
+    For more information, see xref:data-report-v2-api.adoc#answer-report[Answer Report API].
+
+    === Snowflake Semantic View integration APIs
+
+    // SOURCE: SCAL-309867
+
+    ThoughtSpot 26.9.0.cl introduces REST API v2.0 endpoints for managing Snowflake Semantic View integrations programmatically. These APIs allow administrators and data managers to create, search, import, and delete semantic integration configurations without using the ThoughtSpot UI.
+
+    [width="100%"]
+    [options="header"]
+    |=====
+    | Method | Endpoint | Description
+    | `POST` | `/api/rest/2.0/semantic-integrations/create` | Creates a new semantic integration by reading a Snowflake Semantic View and generating a ThoughtSpot data model.
+    | `POST` | `/api/rest/2.0/semantic-integrations/search` | Returns a list of semantic integrations matching the specified filter criteria.
+    | `POST` | `/api/rest/2.0/semantic-integrations/{semantic_integration_identifier}/import` | Re-imports semantic updates from Snowflake and refreshes the associated ThoughtSpot data model.
+    | `POST` | `/api/rest/2.0/semantic-integrations/{semantic_integration_identifier}/delete` | Deletes a semantic integration and its generated ThoughtSpot data model.
+    |=====
+
+    Required privilege: `ADMINISTRATION` or `DATAMANAGEMENT`. If RBAC is enabled, the user also requires the `CAN_CREATE_OR_EDIT_CONNECTIONS` privilege and permission to manage data models.
+
+    For more information, see xref:semantic-integrations-api.adoc[Snowflake Semantic View integration APIs].
+
+    === Spotter Memory — General Availability
+
+    // SOURCE: SCAL-306173
+
+    The Spotter Memory feature is generally available from 26.9.0.cl. The memory APIs introduced in 26.8.0.cl (`POST /api/rest/2.0/ai/memory/import` and `POST /api/rest/2.0/ai/memory/export`) are enabled by default on all ThoughtSpot Cloud instances. Administrators can manage and audit Spotter training data programmatically without enabling a feature flag.
+
+    For more information, see xref:spotter-ai-memory-api.adoc[Spotter memory APIs].
+
+    === Spotter Agent — Conversation sharing APIs
+
+    // SOURCE: SCAL-306173 (aug.26.mt)
+
+    ThoughtSpot 26.9.0.cl introduces REST API v2.0 endpoints for sharing saved Spotter agent conversations with other users or groups. Shared conversations are always `READ_ONLY`.
+
+    [width="100%"]
+    [options="header"]
+    |=====
+    | Method | Endpoint | Description
+    | `POST` | `/api/rest/2.0/ai/agent/conversations/{conversation_identifier}/share` | Shares a saved Spotter conversation with specified principals. Use `grant` and `revoke` arrays to manage access.
+    | `GET` | `/api/rest/2.0/ai/agent/conversations/{conversation_identifier}/get-shared-content` | Returns the content of a shared Spotter conversation — messages, data sources, and answer details.
+    | `GET` | `/api/rest/2.0/ai/agent/conversations/{conversation_identifier}/get-share-info` | Returns sharing metadata — the list of principals the conversation is shared with and their access levels. The `is_shared_content_outdated` flag indicates if the shared snapshot is stale.
+    |=====
+
+    For more information, see xref:spotter-agent-apis.adoc#_sharing_spotter_conversations[Sharing Spotter conversations].
+
+    === KPI Sparkline setting in metadata search response
+
+    // SOURCE: SCAL-320899
+
+    The `POST /api/rest/2.0/metadata/search` API response now includes the `isSparklineEnabled` field in the `AnswerSpecHeader` object for KPI chart type answers. This boolean field indicates whether the sparkline trend line is enabled for the KPI visualization.
+
+    * `true` — the sparkline trend line is enabled.
+    * `false` — the sparkline is disabled.
+    * Absent — the answer was saved before this release and has not been re-saved. Treat an absent field as unknown, not as `false`.
+
+    === Outline Encoding — BYOC Muze
+
+    // SOURCE: SCAL-317550
+
+    ThoughtSpot 26.9.0.cl promotes mark outline color to a first-class data-driven encoding channel in the Muze charting library (BYOC). Developers building custom charts with Muze can now bind a data field to `encoding.outline` to produce ordinal color palettes (for categorical fields) or continuous gradient ramps (for measures), with full legend rendering and legend-to-mark interaction.
+
+    The static `outline` config (`{ fill, color, width, dash }`) remains fully backward compatible. Supported mark types: Point, Bar, Arc.
+
+    === Personalized Views TML portability — General Availability
+
+    // SOURCE: SCAL-307284
+
+    The Personalized Views TML portability feature introduced as Early Access in 26.8.0.cl is generally available from 26.9.0.cl.
+
+    * The `author` field in Personalized View TML maps to the view owner's username or email, ensuring ownership is retained when a Liveboard is promoted across clusters or orgs.
+    * The `obj_id` field provides a stable cross-environment identifier for Personalized Views.
+    * Smart merge import: when importing a Liveboard TML that contains Personalized Views, ThoughtSpot preserves views that exist only in the target environment, appends new views from the imported TML, and updates views present in both.
+
+    For more information, see xref:tml.adoc#personalized-views-portability[Personalized Views portability in TML].
+
+    === Connection configuration — Scheduled Liveboards process type
+
+    // SOURCE: SCAL-312738
+
+    ThoughtSpot 26.9.0.cl adds `SCHEDULED_LIVEBOARDS` as a new process type for Embrace connection configurations. Administrators can assign the Scheduled Liveboards process to a connection configuration, enabling ThoughtSpot to use the associated credentials when running scheduled Liveboard delivery jobs. Configurable via:
+
+    * `POST /api/rest/2.0/connection/configuration/create`
+    * `PUT /api/rest/2.0/connection/configuration/{configuration_identifier}/update`
+
+    === AI Context — Spotter Optimization tab
+
+    // SOURCE: SCAL-277656
+
+    The AI Context generation UI is revamped in 26.9.0.cl. A new *Spotter Optimization* tab is introduced in the data model editor for managing AI context, replacing the previous AI Context panel. The tab provides a more streamlined interface for reviewing and editing auto-generated descriptions for columns and joins.
+
+    No changes to the AI context REST API endpoints in this release.
