# Changelog

> What's shipped recently in Summand.

User-facing changes worth knowing about, newest first.

For real-time deploys and infra status, see [status.summand.com](https://status.summand.com).

## May 2026

* **V2 sharing model** — sharing now splits into two distinct concepts: **filing** (single-parent ownership inside a workspace) and **publication** (multi-target read access for users, workspace members, or showcase audiences). All authorization is enforced through OpenFGA. See [Sharing](/concepts/sharing).
* **Workspace as the share target for connectors and datasets** — the grant model now consistently treats the workspace as the primary owner, with publications layered on top.

## April 2026

* **Workspace detail pages** — drill into a workspace to see all of its connectors and datasets in one view.
* **Workspace listing redesign** — clearer cards, faster load.

## March 2026

* **Fivetran connector** — analyze any Fivetran-supported source (Databricks, Redshift, Oracle, SaaS APIs) without writing a native driver. See [Fivetran](/data-sources/fivetran).
* **Iceberg-native reads** — for Iceberg tables, Summand now reads via Athena `$files` and `$snapshots` instead of bundling pyiceberg in Lambda. Faster, lighter, more accurate.
* **MFA enforcement for shared private datasets** — accessing a private dataset shared with you now requires a fresh MFA challenge. See [MFA](/enterprise/mfa).

## Earlier in 2026

* **Experiments and components** — analysis is now configured as scheduled component runs against a dataset or view, replacing the older "pick a target column at upload" model. Target column moved from being a dataset field to being a typed input on the **Predictors** component. See [Experiments](/concepts/experiments) and [Components](/concepts/components).
* **Views** — saved SQL transformations with a visual builder, hand-edit code mode, and live Athena preview. Cross-dataset joins supported. Summand can also draft views from chat. See [Views](/concepts/views).
* **Delta Sharing connector** — Databricks UniForm shares with Iceberg-backed incremental refresh. See [Delta Sharing](/data-sources/delta-sharing).
* **Azure SQL connector** — Azure SQL Database and Managed Instance via TDS.

## February 2026

* **Multi-runtime semantic-layer pipeline** — analysis components dispatch to Lambda or ECS based on workload size, cutting cold-start latency on small datasets.
* **SUM-140 Distributed Map** — Step Functions Distributed Map for parallelizing per-component work across large datasets.

## January 2026

* **v1.0.0 GA** — Summand exits beta. Pricing solidified to Free / Pro \$99 / Education / Enterprise. See [Pricing](/pricing).
* **Per-account Pro pricing** — flat \$99/month, not per-seat.
* **Education tier** — full Pro features for verified `.edu` users.
* **Enterprise SSO** — WorkOS-based SAML 2.0 / OIDC, replacing the prior Cognito-based implementation.

## Earlier

* **Surprise finding** — flag rows the predictor model considers unusual, ranked by confidence.
* **Summand assistant** — the in-product AI assistant, powered by Claude with grounding from the semantic layer.
* **Database connectors** — direct PostgreSQL, MySQL, Snowflake.
* **EBM-based predictor component** — Explainable Boosting Machines as the default model class, replacing earlier black-box gradient boosting.
