v2.0.0-rc.1

2.0.0-rc.1

Released September 02, 2026

Features

• Add Exasol adapter (Phase 1): connection/auth with TLS and timeout profile options, metadata adapter, agate/seed type conversion (incl. HASHTYPE) and typed SQL literals, reserved-keyword auto-quoting, and the full macro bundle — materializations (table/view/incremental append·merge·delete+insert·microbatch), snapshots (timestamp/check, hard deletes), model contracts and constraints, on_schema_change, grants, persist_docs for tables and views, catalog generation, source-freshness, cross-database utils (dateadd/datediff/last_day/hash/bool_or/listagg/safe_cast/equals/split_part), distribute_by/partition_by/primary_key configs, and interactive dbt init setup
• Add Databricks query tags with automatic dbt metadata and profile- and model-level configuration. (#15701)
• Fusion accepts Databricks Python environment_key and environment_dependencies and uses them on serverless job submit (databricks/dbt-databricks#1636). (#15966)
• Add parse-safe views (dbt.graph_nodes, dbt.models, dbt.seeds, dbt.tests, dbt.snapshots, dbt.sources, dbt.analyses, dbt.operations, dbt.functions, dbt.columns) so standalone querying of an exported index (views.sql) never silently exposes a compile-only or never-populated column at parse time.
• [ClickHouse] New configs available: definer, sql_security, inserts_only. Available but not working yet: projections, codec. (#14585)
• [ClickHouse] Model settings and query_settings configs now render into DDL, and version-gated DDL uses the real server version via a once-per-process probe. (#14585)
• [ClickHouse] clickhouse_s3source() renders the s3() table function, and model contracts are enforced end-to-end (constraint rendering, per-column codec/ttl, real column types). (#14585)
• Track ref()/source()/this call provenance during Jinja rendering (on_this_reference listener hook), powering the dbt.hard_coded_reference (DBT05) lint rule (#16080)
• [ClickHouse] Incremental strategies now resolve and validate exactly like the Python adapter (delete+insert, insert_overwrite, microbatch), and on_schema_change (fail/append_new_columns/sync_all_columns) works on incremental models with codec-aware ALTERs. (#14585)

Fixes

• Fix regression in log-format-file use (#15685)
• Allow Databricks incremental models to use delete+insert with correctly quoted unique keys (#15250)
• Include invocation IDs in default Databricks query comments and preserve run-operation connection names (#15689)
• Disambiguate generated generic-test SQL asset paths on name collisions so tests on different models/columns that flatten to the same generated name are no longer silently dropped from the manifest
• Stop the v2 parser emitting a null macros key for unit tests that set overrides without macros, which made dbt-core fail to deserialize the fusion-produced manifest (#16009)
• Accept sequence-valued column_types, mapping-valued event_time, scalar policy_tags, and the legacy data-paths alias to match dbt-core's YAML config acceptance
• Preserve declaration order when rendering Databricks table properties (#16036)
• Databricks: emit INSERT BY NAME REPLACE WHERE only when DBR 18.0+ supports the combination, and warn when insert_overwrite cannot honor REPLACE ON on older clusters (#15999)
• The download-at-install sdist now declares the runtime dependencies and requires-python of the wheel it installs, so uv pip install dbt-core/dbt-oss no longer produces an unimportable package
• Apply Databricks model and column constraints only when contract.enforced is true (#16056)
• Accept the config value shapes dbt Core tolerates but Fusion rejected - mapping-valued constraints, list-valued dist, and unquoted YAML 1.1 booleans (yes/no/on/off) in contract.enforced, contract.alias_types, docs.show, and the BigQuery partition_by booleans
• Keep a singular test that refs a disabled model in the manifest nodes with enabled=false, and stop emitting a user-visible NodeNotFoundOrDisabled warning for it, matching dbt-core

Under the Hood

• The oss CLI now builds as a binary named dbt instead of dbt-sa-cli (build output is at target/<profile>/dbt)
• Pre-release dbt-core sdists (2.x and up) now print an install-time notice pointing at the dbt and dbt-oss distributions

Security

• Skip symlink, hard link, and device entries when extracting package tarballs instead of extracting them as-is
