Two weeks of steady shipping, headlined by the one you've been asking for: DocuSign is now a first-class StackAI integration - plus ClickHouse support, a redesigned projects dashboard, and a long tail of improvements and fixes.
Big Features
DocuSign: Full Envelope & Template Actions
Getting documents signed is at the heart of so many business processes, but until now DocuSign was out of reach for your workflows. This release ships a complete DocuSign action suite - list and fetch envelopes, send envelopes from templates, download signed documents, check recipient signing status, void in-flight envelopes, and browse your templates. It also adds a new connection type, so you can connect your DocuSign account in minutes.
Connectors: Choose Exactly Which Actions Are Available
Rolling out an integration to your team used to be all-or-nothing — enabling a connector exposed every action it supports. Now admins can enable or disable individual actions per connector, and the restriction is enforced at runtime, not just hidden in the UI. Give your builders Salesforce reads without Salesforce writes, and keep governance simple.
Files Node: Partial Success & Fallback Branches
Previously, if you uploaded five files and one failed to process, the entire workflow failed with it. The Files node now supports partial success - the four good files keep flowing - and you can wire a fallback branch to handle the failures gracefully. Especially valuable when your workflows run as APIs inside a bigger system and need to degrade gracefully instead of falling over.
New Integrations & Actions
ClickHouse - new integration: query ClickHouse databases with username/password or JWT auth
Meta - Llama models now served via AWS Bedrock (4 models)
HubSpot - Create Company, Get Ticket, Create & Update Ticket actions, plus improved custom object filtering

Workable - Get Candidate Comments action
Azure SQL - multi-row insert and a unified DML action
Outlook - subfolder support in the trigger picker and a new query mode for search
OneDrive - markdown file support in Create/Update File actions
SharePoint - recursive folder listing in List Folder Content
Confluence - dynamic dropdowns for space, page, and label selection
Slack - thinking-steps streaming actions to show agent progress in-channel
Quality of Life
Connections: Redesigned Connection Modal
Setting up a new connection is the first thing every builder does, so it should feel great. The new connection modal has been redesigned from the ground up, and your recent connections now show each app's unique icon so you can spot the right one at a glance.
Triggers: Day-of-Month Scheduling
Scheduled workflows could run daily, weekly, or at fixed intervals — but "the 1st of every month" required workarounds. Scheduled executions now support day-of-month configuration, so monthly reports and billing-cycle automations can run exactly when they should.
Send Email Node: Attachment Support
The native Send Email node can now include attachments. Generate a report, a document, or a processed file earlier in your workflow and deliver it straight to the recipient's inbox — no third-party email integration required.
MCP Server: Build & Validate Workflows from Your Coding Agent
The StackAI MCP server got a major capability bump: agents can now edit projects, browse the node and action catalogs, and validate workflows before deploying — with expanded node type coverage and smarter guidance for configuring LLM nodes as agents. If you build StackAI workflows from Claude Code or another MCP client, this release makes it dramatically more capable.
Workflow Editor: Per-Action Icons & Expandable Results
Every action node used to wear the same Stack logo, which made dense workflows hard to scan. Nodes now display a distinct icon per action, and the node results panel gains an expand button so you can inspect large outputs without squinting at a cramped pane.
Bug Fixes:
SharePoint nested-file search - searching now finds files nested deep in large libraries instead of missing them when file counts are high.
Apostrophes in file names - SharePoint and OneDrive search/get file actions no longer fail on names containing apostrophes.
Batch run isolation - batch executions no longer share workflow state between runs, eliminating cross-run contamination.
Prompt editor cursor position - the LLM prompt editor now preserves your cursor position on blur instead of jumping to the end.
Action node defaults - newly added action nodes now render their schema default values correctly.
Outlook stale connections - connections that expire mid-execution are now refreshed automatically instead of failing the run.
Outlook mailbox deadlocks - parallel runs against the same mailbox no longer deadlock under load.
Gmail trigger resilience - email events now keep flowing even when attachment parsing fails.
Google Drive trigger samples - sample events now populate the correct change type and metadata.
Send HTTP Request node - query parameters passed as part of the URL now work correctly.
Synapse query comments - queries beginning with SQL comments are now accepted instead of being rejected as invalid.
Snowflake database & schema - queries now respect the database and schema selected in the connection.
Microsoft Teams dropdowns - dropdown fields now accept templated string inputs from upstream nodes.
Human-in-the-loop resume - workflows using local LLMs no longer fail to rehydrate after an approval resume.
LLM max output tokens - a sensible default now applies when a model's output token limit isn't configured.
Parser settings honored - knowledge base parsing now consistently respects your explicitly configured providers and LlamaParse settings.
Connection modal layering - fixed broken z-indexing that let the knowledge base connection modal render behind other elements.
