v1.50.0

What's new in Recce v1.50.0

We're excited to announce the latest version of our software, bringing you enhanced features and improvements.
Here's what's new:

🔒 Security

This release includes a security fix based on a responsibly disclosed report. Thank you to Sitampan (@hxcbtc) for reporting the issue and helping improve Recce’s security.

🔎 See Downstream Impact of Whole-Model Changes (beta)

When a change touches every row of a model — a WHERE, GROUP BY, or JOIN change — Recce now marks it at the source and flags every impacted model downstream, with the sidebar naming the upstream model that caused it so you can trace the blast radius.

Opt in with --whole-model-impact (off by default).

🤖 Structural Model Analysis in the MCP Server

New analyze_model tool parses a model's compiled SQL to return its structure (refs, projections, filters, joins, aggregations) plus downstream column impact — single-environment, no base env or git history needed.

🎨 Clearer Lineage, Clearer Language

• Cleaner nodes on hover — status icons stay visible; model actions move to a floating toolbar, and tooltips now show materialization/resource type.
• Redesigned node sidebar — key metadata visible without scrolling, schema-diff actions in the Columns tab, deprecated Sandbox button removed.
• Plain-language change labels — "Breaking" / "Partial Breaking" / "Non Breaking" become Model-Wide Change / Column Change / Additive Change.

🐛 Bug Fixes

• Value Diff on Snowflake — normalize column case before quoting
• Honest column-change status when CTE-internal changes can't be resolved

What's New in Recce v1.46.0

What's New

Lineage Tab in the Model Detail Panel

A new Lineage tab is now the first tab in the Model Detail panel, showing the focused model's direct upstream parents and direct downstream children with a back-path breadcrumb that surfaces one step of navigation history at a time.

• #1345

Improvements

Faster Cloud Lineage on Large Projects

Recce Cloud now serves the lineage view, the initial lineage load, and node selection noticeably faster, especially on large projects. Run recce init --cloud once and Cloud loads lineage from precomputed data instead of recomputing on every request. Local recce init behavior is unchanged.

• #1334
• #1335
• #1336

MUI v7 to v9 Refresh

The shared @datarecce/ui library is now on MUI v9, keeping the Recce UI on a supported major and clearing the way for upcoming Material You components.

• #1333

Bug Fixes

Reliable run_check Completion for AI Agents Using the Recce MCP Server

AI agents using the Recce MCP server now reliably finish a run_check, and the PR review checklist sync stops showing wrong status. On a local integration test against jaffle_shop_golden PR #26, approved checks went from 1/10 to 8/10.

• #1342

Faster Model Detail Panel Open on Node Click

Clicking a node in the lineage panel now opens the Model Detail panel faster, with one round-trip instead of two.

• #1346
