dbt Core vs Fluent Bit: at a glance
What is dbt Core?
dbt 2.0 dev.44 adds ClickHouse clusters, grants and clone ahead of the next v2 release.
dbt 2.0 GA split the project into a proprietary 'dbt' binary and dbt-oss, and the 1.x line now works as a bridge to it. The 2.0.0-dev.44 build adds ClickHouse cluster support with distributed materializations, grants and dbt clone, and lets Lake Compute models ref() Databricks managed Delta tables. On the 1.x side, 1.13.0rc1 drops Python 3.10 and 1.11.17 fixes git package installs under newer libcurl.
What is Fluent Bit?
Fluent Bit 5.2 adds its own typed scripting language for log processing
Fluent Bit 5.2.0 shipped on 9 November. Its main addition is Fluent Typed Scripting, a processor with reusable typed policy packs, JSON field decoding and editor definitions, alongside the experimental browser runtime, output throttling and YAML config generated from CLI flags. The release also carries dozens of input hardening fixes, from OTLP decoding limits to syslog overflow and an AWS credential URI bypass. Experimental browser SDK builds from master keep appearing several times a day, each marked as unsupported for production.

◆ Current state
dbt 2.0 GA split the project into a proprietary 'dbt' binary and dbt-oss, and the 1.x line now works as a bridge to it. The 2.0.0-dev.44 build adds ClickHouse cluster support with distributed materializations, grants and dbt clone, and lets Lake Compute models ref() Databricks managed Delta tables. On the 1.x side, 1.13.0rc1 drops Python 3.10 and 1.11.17 fixes git package installs under newer libcurl.
◆ Where it's heading
dbt Labs keeps two jobs running on 1.x: older lines get patches when the environment breaks them, and the newest line makes projects ready for v2. The 1.13 GA is the next milestone on that bridge.
◆ Prediction
Expect 1.13.0 final soon after the release candidate, with v2-compatibility changes. More 1.11 patches will likely follow only when outside breakages force them.

Fluent Bit 5.2 adds its own typed scripting language for log processing
◆ Current state
Fluent Bit 5.2.0 shipped on 9 November. Its main addition is Fluent Typed Scripting, a processor with reusable typed policy packs, JSON field decoding and editor definitions, alongside the experimental browser runtime, output throttling and YAML config generated from CLI flags. The release also carries dozens of input hardening fixes, from OTLP decoding limits to syslog overflow and an AWS credential URI bypass. Experimental browser SDK builds from master keep appearing several times a day, each marked as unsupported for production.
◆ Where it's heading
After a month of hardening on 5.1, the 5.2 line puts new surface on top: a typed transform language that also runs in the browser build. Fluent Bit is moving from a collector configured with Lua snippets toward an agent with its own checked policy format.
◆ Prediction
Expect 5.2.x patch releases soon fixing regressions in the new FTS processor, and more FTS policy packs; the browser SDK is likely to stay labelled experimental for now.
