If you're still on Classic, the window for self-service migration closed. The same changelog notes two operational traps for Forward users — the CLI now demands Python 3.11 or later, and Tinybird Local's arm64 image refuses to start on hosts with 16 KiB or 64 KiB kernel pages, a class of machine that includes some recent Apple silicon and ARM server setups. ### dbt moves its defaults forward The week's biggest developer-facing shift is in [dbt-core's 1.13 beta](https://github.com/dbt-labs/dbt/releases/tag/v1.13.0b1), which flips every flag introduced in 1.9 and 1.10 to default true — a breaking change for projects that never opted in. It also bundles the opt-in dbt-state plugin, adds a `dbt login` command for platform authentication, and introduces a `--use-v2-parser` flag that hands parsing to Fusion, with parser fixes for duplicate-metric partial parsing and a circular-selector recursion crash on Windows. The 1.12 and 1.11 maintenance lines picked up the smaller pieces of that work: [wildcard FQN selectors match nested models](https://github.com/dbt-labs/dbt/releases/tag/v1.12.6) regardless of subfolder depth, the v2 parser's logs now relay cleanly through `--log-format otel` (fixing a latent bug where a stray stderr line could abort a `--warn-error` run), and [package tarball downloads are validated](https://github.com/dbt-labs/dbt/releases/tag/v1.11.16) to stay inside the dbt downloads directory. On the v2 side, [catalog.json comes back for `dbt build --write-catalog`](https://github.com/dbt-labs/dbt/releases/tag/v2.0.8) after a preview regression silently skipped it, spurious TableNotFound errors during analyze are gone, and the PyPI wheels now support Python 3.10. ### ClickHouse's quiet background hum ClickHouse's 25 releases across four channel lines this week are routine patch churn — the stable and LTS branches advancing in lockstep, with nothing flagged as a headline change. Worth knowing they exist if you pin versions, but nothing here should change how you build. The substance came from [a native TCP client for .NET](https://clickhouse.com/blog/introducing-the-blazing-fast-native-tcp-client-for-net) that promises faster reads and inserts with fewer allocations, columnar APIs, POCO support, and a migration path off HTTP. Alongside it, [ClickStack added built-in z-score anomaly detection](https://clickhouse.com/blog/scaling-clickstack-alerting-anomaly-detection) on existing charts plus a sharded scheduler sized for tens of thousands of alerts migrated from tools like Grafana, and the team published a [head-to-head CostBench result against Redshift Serverless](https://clickhouse.com/blog/clickhouse-vs-redshift-serverless-real-time-performance-per-dollar). Two posts drill into the plumbing: how [Managed Postgres and ClickHouse work as one stack](https://clickhouse.com/blog/postgres-at-open-house-nyc), with a live WalShadow demo replicating Postgres in under a second, and a careful hunt for [a 32 ms tail-latency spike](https://clickhouse.com/blog/chasing-32ms-tail-latency-clickhouse) traced to unbatched Native protocol metadata packets overflowing a reset congestion window — a good read if you've ever blamed the query planner for network physics. ## Releases covered ### ClickHouse - [Introducing the (blazing fast!) native TCP client for .NET](https://clickhouse.com/blog/introducing-the-blazing-fast-native-tcp-client-for-net) - [Scaling ClickStack alerting with built-in anomaly detection](https://clickhouse.com/blog/scaling-clickstack-alerting-anomaly-detection) - [Why Redshift Serverless can’t match ClickHouse Cloud for real-time analytics](https://clickhouse.com/blog/clickhouse-vs-redshift-serverless-real-time-performance-per-dollar) - [Postgres at Open House NYC](https://clickhouse.com/blog/postgres-at-open-house-nyc) - [Chasing that 32 ms tail latency in ClickHouse](https://clickhouse.com/blog/chasing-32ms-tail-latency-clickhouse) ### dbt Labs - [dbt v1.13.0b1 flips 1.9/1.10 flags to default true, adds dbt login](https://github.com/dbt-labs/dbt/releases/tag/v1.13.0b1) - [dbt-core v1.12.6 fixes wildcard selectors and v2 parser log output](https://github.com/dbt-labs/dbt/releases/tag/v1.12.6) - [dbt-core v1.11.16 fixes wildcard FQN selectors and validates package download paths](https://github.com/dbt-labs/dbt/releases/tag/v1.11.16) - [dbt-core v2.0.8 restores catalog.json from dbt build --write-catalog](https://github.com/dbt-labs/dbt/releases/tag/v2.0.8) ### Tinybird - [Tinybird Classic sunsets for Free and Developer plans, CLI 5.0.0 requires Python 3.11](https://www.tinybird.co/docs/changelog/2026-10-16-october-week-three)
