🗓️ 2026-01-07

🚀 Features

Worksheets (Public Preview)

Worksheets

Run SQL queries directly in the Ascend UI with the new Worksheets editor. Position your cursor on any query and click Run to execute it, or select multiple queries to run them in sequence. A visual highlight bar shows exactly which queries will execute.

Worksheets are stored per-user in worksheets/<your-email>/ as regular .sql files you can rename and reorganize. Saving doesn't trigger builds. You can also run Worksheets in Deployments to query production data, though saving is disabled there.

Learn more about Worksheets →

Regex-based retry clauses

Define pattern-specific retry rules for Components with independent counters per error type:

retry_strategy:
  retry_clauses:
    - pattern: "503.*Service Unavailable"
      max_attempts: 10
    - pattern: "timeout"
      max_attempts: 3

Each pattern maintains its own retry count, so transient 503 errors won't exhaust your timeout retry budget.

Learn more about retry clauses →

Notification center

A new notification center in the navbar collects toast notifications with persistent history. Notifications are scoped to your user — click the bell icon to review your past notifications, dismiss individual items, or clear all. Toasts now dismiss 3x faster since you can always find them in the notification center.

🚀 Features

🤖🐐 New Otto capabilities: Otto can now be used as an Action in Automations to respond to Flow events, analyze data patterns, and execute actions across multiple platforms:

automation: name: otto-notifications enabled: true triggers: events:

sql_filter: json_extract_string(event, '$.data.flow') = 'transform-demo' types:
- FlowRunError
- FlowRunSuccess

actions:

type: run_otto name: run-otto config: prompt: >-

Instructions

You are being invoked at the end of a flow run. Your job is to assess changes in flow run behavior, and send a Slack message to keep other users updated. You cannot ask for help or clarification; you must do this end-to-end on your own based on your own judgement. Your last action should always be to post a message to Slack.

Flow run analysis rules

Analyze flow success / failure by fetching the maximum number of flow runs.
1. If the flow run was a success and the previous flow run was also a success, send a funny message congratulating the team on another smooth run.
2. If the flow run was a success and the previous flow run was not, send an exciting and congratulatory messages celebrating the flow is now fixed, and congratulating whichever user did the fixing (check git history).
3. If the flow run was a failure and the previous flow run was also a failure, send a sad message imploring somebody to fix it.
4. If the flow run was a failure and the previous flow run was not, send a big alert message. You should try to identify who broke the flow, and even @ mention them if you can. You should also try to analyze the changes and suggest fixes if possible.
Additionally, you should make heavy use of git history and file reading calls to help track down details that may be relevant.

Slack message and notification

At the end of your analysis, you must post a message to Slack in the appropriate channel.

Your slack post message should:
- include a link to the flow run: https://[runtime.link_url]/flows/[flow_name]/[run_name]
- be formatted for Slack rendering, which is different than markdown
- when @ mentioning users, look up their profile so you can reference their actual id

### 🌟 Improvements

- [Application](/concepts/application/application.mdx) Components can now access Flow parameters during build time, enabling conditional Component generation based on Profile and Flow parameter values.

## 🗓️ 2025-07-07

### 🚀 Features

- 🤖🐐 New Otto capabilities:

- Otto now supports [custom agents](/how-to/otto/agents.mdx) for creating specialized behaviors tailored to your workflows. Define agents in markdown with custom traits and tool access.

  - Tool inclusion supports wildcards: `[category].*` for all tools of a specific type, or `*` for everything. Example:

  ```md title="otto/agents/custom_agent.md"
  ---
  otto:
    agent:
      name: Standup Reporter
      mcp_servers:
        - slack
      model: gpt-4o
      model_settings:
        temperature: 0.1
      tools:
        - "*"
  ---

  # Standup Reporter

write_custom_chunk.yaml
component:
  write:
    connection: write_s3
    input:
      name: my_component
      flow: my_flow
    s3:
      path: /some_other_dir/
      formatter: json
    part_file_rows: 1000

🛠️ Bug fixes

Fixed database Read Components (PostgreSQL, MySQL, Microsoft SQL Server, Oracle) converting SQL null values to the literal string 'None' when loading query results into PyArrow arrays. Null values are now properly preserved.
- This change affects all pipelines using database Read Components across all Data Planes.
- If you previously added cleanup steps to handle 'None' string values, you can remove them.

🗓️ 2025-06-23

🚀 Features

🤖🐐 New Otto capabilities: Otto now renders tool calls, showing which tools are called, their inputs, and outputs.

🌟 Improvements

Flow runner process for my_flow/fr-01977f3c-845b-72a1-b225-4327835f8434 exited with code -9.
Exit code -9 usually means the kernel's Out-Of-Memory (OOM) killer terminated the process after it exceeded its memory limit.
Consider increasing the runner size or optimizing the workflow's memory usage.

🛠️ Bug fixes

Fixed build history calendar days outside the current month not being selectable.
