ClickHouse Releases Stack Up as dbt Core Hits New Milestones
August 17–23, 2026
ClickHouse dominates the week with a flurry of patch releases and a security-focused dbt Core update, while dbt Core v1.12 goes GA and beta features push toward 2.0.
ClickHouse’s steady cadence of fixes
ClickHouse shipped a remarkable eight releases this week, spanning its LTS and stable channels. The v26.3.21.7-lts and v26.3.19.3-lts patches, along with v26.7.5.10-stable and v26.7.4.58-stable, continue the project’s commitment to stability across both major version tracks. Meanwhile, the older v25.8.32.4-lts, v25.8.31.9-lts, and v25.8.30.16-lts releases show the LTS branch is still receiving critical backports. Sandwiched between these, the v26.6.3.62-stable and v26.5.7.64-stable releases round out a week where no single fix dominates — instead, it’s the sheer volume of incremental improvements that speaks to the project’s operational maturity.
dbt Core: from security patches to 2.0 previews
The biggest story for dbt users is the dbt Core v1.12 general availability announcement, which arrived alongside two security-focused patch releases. Both v1.12.3 and v1.11.14 pin sqlparse to a version that fixes four denial-of-service CVEs, with v1.12.3 also resolving an Azure Blob Storage upload issue where the missing x-ms-blob-type header caused 400 MissingRequiredHeader errors on Azure-hosted regions. For forward-looking teams, the v2.0.0-beta.2 release adds ClickHouse Dictionary materialization, index definition support, and Entra bearer token authentication for dbt-fusion fabric — signaling where the project is heading.
ClickHouse’s thought leadership
Beyond releases, ClickHouse published two technical posts this week. The PostgreSQL 19 monitoring overview explores new observability features, while a deep dive into storage performance presents a local NVMe versus EBS benchmark from a POSETTE 2026 talk, complete with production setup details. These posts, alongside the Tinybird changelog entry about smarter materialized view dependency tracking, show the ecosystem’s broader focus on operational insight and performance tuning.
