What's New is an index, not a publisher: every entry below links to the vendor's own release notes, which are the authoritative source. Entries are labelled where they are hand-curated sample data, pre-releases, or drawn from a secondary source such as a developer blog.

Reuse: the summaries, labels and curation here are © What's New. Quote freely with attribution and a link back; wholesale republication of the corpus is not permitted — terms: https://whatsnew.fyi/terms. The vendors' own release notes remain their publishers'.

- **added** — Add Exasol adapter with connection/auth, TLS and timeout profile options, metadata adapter, agate/seed type conversion with HASHTYPE support, typed SQL literals, reserved-keyword auto-quoting, materializations (table/view/incremental), snapshots, model contracts and constraints, on_schema_change, grants, persist_docs, catalog generation, source-freshness, cross-database utilities, distribute_by/partition_by/primary_key configs, and interactive dbt init setup
- **added** — 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) for standalone querying of an exported index without exposing compile-only or never-populated columns at parse time
- **added** — Add new ClickHouse configs: definer, sql_security, inserts_only
- **added** — Track ref()/source()/this call provenance during Jinja rendering via on_this_reference listener hook to power the dbt.hard_coded_reference (DBT05) lint rule
- **fixed** — Fix regression in log-format-file use
- **fixed** — Include invocation IDs in default Databricks query comments and preserve run-operation connection names
- **changed** — 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
- **changed** — The oss CLI now builds as a binary named dbt instead of dbt-sa-cli
- **security** — Skip symlink, hard link, and device entries when extracting package tarballs instead of extracting them as-is

##### 2.0.0-dev.30

Released August 27, 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 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](https://github.com/dbt-labs/dbt-core/issues/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](https://github.com/dbt-labs/dbt-core/issues/16080))

###### Fixes

- Fix regression in log-format-file use ([#15685](https://github.com/dbt-labs/dbt-core/issues/15685))
- Include invocation IDs in default Databricks query comments and preserve run-operation connection names ([#15689](https://github.com/dbt-labs/dbt-core/issues/15689))
- 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

###### 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`)

###### Security

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