2.0.0-alpha.3

Released June 29, 2026

Features

[dbt-fusion] Sqlfluff parity
[dbt-fusion] For versioned models, automatically create a view at the unsuffixed model name (e.g. dim_customers) pointing to the latest version (e.g. dim_customers_v2). Enabled by default; disable per-model with latest_version_pointer: {enabled: false} or globally with the project flag latest_version_pointer_enabled_by_default: false. Customize the pointer alias via the latest_version_pointer.alias config or by overriding the generate_latest_version_pointer_alias macro.
[dbt-fusion] Redshift: use SHOW GRANTS ON TABLE for grants when datasharing is enabled
[dbt-fusion] Make the maximum seed size hashed for state:modified comparison configurable via --maximum-seed-size-mib, the DBT_MAXIMUM_SEED_SIZE_MIB (or DBT_ENGINE_MAXIMUM_SEED_SIZE_MIB) env var, and dbt_project.yml flags (default 1 MiB; 0 disables the limit). Seed contents are now hashed incrementally with line-ending normalization, plus a Windows legacy-checksum fallback for state comparison.
[dbt-extension] Signing in from the extension now uses the dbt login command.
[dbt-fusion] Support catalog federation between Snowflake Horizon and Unity Catalog
[dbt-fusion] Added support for Javascript UDFs in Snowflake and BigQuery
[dbt-fusion] Setup catalogs.yml to provide json schemas.
[dbt-fusion] Add dbt man --schema catalogs to export a type-discriminated JSON schema for catalogs.yml v2
[dbt-fusion] Issue compatibility warnings for package versions based on manual compatibility verification when available in Package Hub
[dbt-fusion] Support the insert_overwrite incremental strategy for the Spark adapter
[dbt-fusion] Classification
[dbt-fusion] Honor per-node +compute config on unit_test nodes, allowing a unit_test to override the global --compute flag (e.g. +compute: sidecar under global --compute remote).
[dbt-fusion] Support the reservation config for BigQuery, allowing query jobs to be routed to a specific BigQuery reservation at the profile, project (+reservation), or model ({{ config(reservation=...) }}) level.
[dbt-fusion] Allow the source application identifier sent during OAuth login to be configured via AuthChainBuilder or the DBT_OAUTH_SOURCE_APP environment variable
[dbt-fusion] Expose has_dbt_state on GET /api/v1/capabilities
[dbt-core] support the latest duckdb version 1.5.4 (#15279)

Fixes

[dbt-fusion] BigQuery source freshness now correctly handles dotted project IDs (e.g. mycompany.io) by using relation component accessors instead of splitting the FQN on '.'. Also fixes a secondary bug where each per-dataset query included a redundant table_id IN (...) filter built from relations in unrelated datasets.
[dbt-fusion] (fix redshift) always quote materialized view path
[dbt-fusion] --write-index no longer produces catalog.json (was unintended side effect of #10750; pass --write-index --write-catalog to restore). --write-metadata alone no longer queries the warehouse. Catalog data is now fetched at most once per invocation and shared across all consumers.
[dbt-fusion] Discover source() calls inside conditional branches that evaluate to false during the parse render.
[dbt-fusion] Fix field-level manifest conformance gaps for metrics and semantic_models: metric label falls back to name at resolve time (matching dbt-core); semantic model entity description defaults to empty string and entity config defaults to {meta: {}} when unset. Fields where Fusion emits richer values than dbt-core (tags, meta, unrendered_config) are left as-is — these are improvements, not bugs.
[dbt-fusion] Databricks: under catalogs v2, use CREATE OR REPLACE TABLE for managed Iceberg tables (table_format: iceberg) regardless of file_format, instead of plain CREATE TABLE
[dbt-fusion] Support incremental materializations on the Spark adapter (append strategy)
[dbt-fusion] Surface cached data test failures in dbt State builds
[dbt-fusion] LSP fix code lens when static analysis off
[dbt-fusion] Report dbt State-reused data tests as reused in dbt test output
[dbt-fusion] sidecar: empty-string CAST to NULL, *_from_parts zero-tuple to NULL, unknown format string to NULL, timestamp_ltz_from_parts bridges
[dbt-fusion] Snapshot nodes now correctly serialize config.materialized as snapshot instead of table in the manifest
[dbt-fusion] ISO date format support for microbatch dates.
[dbt-fusion] Accept dbt-core-style type annotations on macro arguments (e.g. param: str)
[dbt-fusion] Singular tests whose ref() or source() calls target a node that doesn't exist in the project are now excluded from the schedule (NodeNotFoundOrDisabled warning at parse time, no execution), matching dbt-core behavior. Previously Fusion scheduled and executed those tests, hitting a dbt1501 render error.
[dbt-fusion] Accept dotted snapshot block names (e.g. {% snapshot snp.sql %}) by stopping at the first dot, matching dbt-core behavior
[dbt-fusion] Support comma-separated expression lists in Jinja do blocks (e.g. {%- do a.append(x), b.append(y) -%})
[dbt-fusion] fix standardize_grants_dict crash when show_grants returns 0 rows (Redshift, Snowflake, Databricks)
[dbt-fusion] Support Jinja2 filter postfix attribute access (e.g. rows|first.col) in minijinja parser
[dbt-fusion] Spark: correctly classify existing relations as views so view models drop with DROP VIEW instead of DROP TABLE
[dbt-fusion] Promote SA to strict for unit tests with overridden compute, allow unit test nodes to access LP if compute is sidecar.
[dbt-fusion] Test nodes on disabled models are now emitted into manifest.disabled instead of being silently dropped
[dbt-fusion] Give each microbatch batch its own statement-result registry so concurrent_batches=true models no longer fail with "The 'statement' result named '' has already been loaded into a variable"
[dbt-fusion] Unit tests on models that call dbt UDFs via function() no longer fail with a spurious JinjaError (dbt1501); the tested model's function dependencies are now allowed during unit test rendering
[dbt-fusion] finally and consciously decouple the DuckDB adapter from it's weird cousin Extended
[dbt-fusion] Fix BigQuery get_relation crash during replay when the INFORMATION_SCHEMA.SCHEMATA location query returns an empty (zero-column) batch; get_dataset_location now returns no location instead of erroring.
[dbt-fusion] Map Spark EXTERNAL/MANAGED relation types to table so DROP renders a valid drop table instead of an invalid drop external. Spark 4 reports managed Hive tables as EXTERNAL (TRANSLATED_TO_EXTERNAL), which broke --full-refresh over Thrift
[dbt-fusion] Prevent dbt system uninstall from removing a binary owned by Homebrew, pip, or winget; surface the package manager's uninstall command instead
[dbt-fusion] preserve legacy seed checksum compatibility
[dbt-fusion] Ensure that persisted_docs configs for seeds are deserialized to the manifest.
[dbt-fusion] Add support for databricks configs view_update_via_alter, incremental_apply_config_changes, and use_safer_relation_operations
[dbt-fusion] Fix dbt State support for custom materializations
[dbt-fusion] Fix manifest emission of null for adapter-specific config fields (sources: external_location, formatter, sync, schema_origin; models: compute, sync, and other adapter extras) — these are now omitted when unset, matching dbt-core behavior
[dbt-fusion] dbt docs serve now emits a clear error when target/index is missing instead of silently exiting with code 1
[dbt-fusion] Log when commands auto-install dependencies without an existing package-lock.yml.
[dbt-fusion] Fix wizard subagents hanging indefinitely due to deadlocked event forwarding, unbounded wait_agent retries, and DuckDB checkpoint race
[fusion] (dbt-adapter): all ambiguous to_rfc3339 calls are mapped to microsecond precision for Bigquery. Unblocks bigquery microbatch use cases.
[fusion] Support lag_tolerance seconds period
[dbt-core] state:modified no longer flags environment-aware warehouse-specific configs (e.g. copy_grants) set as Jinja in dbt_project.yml. (#15263)
[fusion] Fix cached dbt State warning tests
[fusion] Per-version access field on versioned models is now respected
[fusion] ref() version pins now preserve original type (int/float/string) in manifest refs
[dbt-core] state:modified no longer flags environment-aware grants configs set as Jinja in dbt_project.yml (e.g. grants driven by target.name). The unrendered grants config is compared instead of the target-rendered values. Affects seeds in particular. (#15302)
[fusion] Allow tests attached to disabled models to preserve manifest metadata without failing on legacy generic test argument syntax.
[dbt-core] Fix state:modified to no longer flag seeds whose column_types config is set as environment-aware Jinja in dbt_project.yml. (#15286)
[dbt-core] state:modified no longer flags seeds whose quote_columns config is set as environment-aware Jinja in dbt_project.yml. (#15286)
[dbt-core] Report CV10 quoted literal style violations with their own rule identity instead of CV11 casting style. (#15328)
[fusion] Yaml: fix quoted string values parsed as numbers
