The specification, community, and mission remain unchanged, but the governance shift to Apache's foundation signals a maturation of the project's long-term trajectory. For anyone building data products that depend on portable semantic layer definitions, this is a vote of confidence in the standard's stability and vendor-neutral future. All references to "OSI" in code and documentation are now historical, so teams should begin updating their tooling and naming conventions accordingly. ### dbt-core 1.12.0 lands with breaking changes and DAG fixes dbt Labs shipped [dbt-core v1.12.0](/release/rel_wx0j39CK8njVEv_1tYbsf-dbt-core-v1-12-0) on Thursday, a named release that removes the experimental `dbt login` command and the bundled `dbt-state` plugin. The breaking changes also finalize flag defaults that were introduced in earlier 1.x releases, now enabled by default. Teams still on older 1.9 or 1.10 configurations should review their `dbt_project.yml` to ensure their flags are explicitly set. The release also makes `MAXIMUM_SEED_SIZE_MIB` configurable, giving teams more control over seed file size limits. A day earlier, the [1.12.0rc3 candidate](/release/rel_0MnZ7kEnBbmpXj_X871PS-dbt-core-v1-12-0rc3-fixes-dag-dependencies-for-overloaded-udfs) fixed a subtle DAG issue: dependencies declared inside overloaded UDF bodies are now correctly carried onto the root function node, preventing dropped edges in the DAG. The release candidate also reduced parse-time memory overhead through virtualized macros and lazy no-copy manifest views, which should improve performance for projects with large numbers of models. ### Tinybird Classic sunset and ClickHouse's Node.js RowBinary library Tinybird announced that [Tinybird Classic will be sunset for Free and Developer plan workspaces](/release/rel_sHMHOeeJnrCdLThujsOn0-tinybird-classic-sunset-for-free-and-developer-plans), with automatic migration to Tinybird Forward beginning September 15, 2026. Forward remains the primary product experience, offering schema changes, local development, branching, CI/CD, and AI-assisted features. Enterprise plan workspaces are unaffected, but Free and Developer users should plan their migration now. Over at ClickHouse, the team released [@clickhouse/rowbinary](/release/rel_v03Mz3QEE5U_x3auuzJIM-clickhouse-rowbinary-when-your-library-is-also-a-parser-compiler), a Node.js library for reading and writing the RowBinary binary format. The library is notable for its dual nature: it works as a standard importable parser, but also ships as an Agent Skill — a bundled `SKILL.md` file that allows a coding agent to read the specification and write a custom parser rather than calling the library directly. This is an interesting approach to making binary format handling more accessible in agentic coding workflows. ### Data engineering narratives Two blog posts from Dagster and ClickHouse offer practical case studies. Dagster's engineering team wrote about [classifying a million Snowflake columns in nine days](/release/rel_cVdIcJiRiyyHLaqstOHQR-classifying-a-million-snowflake-columns-in-9-days-solo-with-dagster) using a tiered AI classification system with human review, orchestrated through Dagster. The post is a concrete example of how tooling can accelerate data governance workflows at scale. ClickHouse published a deep dive on [replacing a traditional HDB (historical database) with ClickHouse for financial ticker data](/release/rel_KV18_bcJ95hCbI5MXmkmS-replacing-the-hdb-clickhouse-for-historical-ticker-data), covering the architecture decisions that made the switch viable for historical market data serving. A separate post explored [configuring huge pages in ClickHouse Managed Postgres](/release/rel_Bm6MVf2YJcV9coOpIaPw2-how-we-configure-huge-pages-in-clickhouse-managed-postgres), explaining the performance implications of memory page size for Postgres's shared buffer cache. Dagster also released [version 1.13.14 (core) and 0.29.14 (libraries)](/release/rel_JRvu0azDdYLwxIRgUowGT-1-13-14-core-0-29-14-libraries), fixing two errors in the serverless I/O manager related to multi-deployment organizations and storage keys with special characters. ## Releases covered ### ClickHouse - [@clickhouse/rowbinary: when your library is also a parser compiler](https://releases.sh/release/rel_v03Mz3QEE5U_x3auuzJIM-clickhouse-rowbinary-when-your-library-is-also-a-parser-compiler) - [Replacing the HDB: ClickHouse for historical ticker data](https://releases.sh/release/rel_KV18_bcJ95hCbI5MXmkmS-replacing-the-hdb-clickhouse-for-historical-ticker-data) - [How we configure huge pages in ClickHouse Managed Postgres](https://releases.sh/release/rel_Bm6MVf2YJcV9coOpIaPw2-how-we-configure-huge-pages-in-clickhouse-managed-postgres) ### Dagster - [Classifying a Million Snowflake Columns in 9 Days, Solo, with Dagster](https://releases.sh/release/rel_cVdIcJiRiyyHLaqstOHQR-classifying-a-million-snowflake-columns-in-9-days-solo-with-dagster) - [1.13.14 (core) / 0.29.14 (libraries)](https://releases.sh/release/rel_JRvu0azDdYLwxIRgUowGT-1-13-14-core-0-29-14-libraries) ### dbt Labs - [Open Semantic Interchange renamed to Apache Ossie (Incubating)](https://releases.sh/release/rel_mSe-7_EznU23Z73Q-M5x9-osi-is-now-apache-ossie-incubating) - [dbt-core v1.12.0](https://releases.sh/release/rel_wx0j39CK8njVEv_1tYbsf-dbt-core-v1-12-0) - [dbt-core v1.12.0rc3 fixes DAG dependencies for overloaded UDFs](https://releases.sh/release/rel_0MnZ7kEnBbmpXj_X871PS-overloaded-udf-dag-dependencies-fixed-parse-time-memory-reduced) ### Tinybird - [Tinybird Classic sunset for Free and Developer plans](https://releases.sh/release/rel_sHMHOeeJnrCdLThujsOn0-tinybird-classic-sunset-for-free-and-developer-plans)
