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.
What is Hex?
Hex 4.0 rebuilds projects as code so agents can build them from anywhere.
Hex is a data workspace whose agent builds projects, Generative Apps and published eval suites, and can be called from the CLI and API. Hex 4.0, now in public beta, makes projects fully code-defined, lets them be built from outside Hex, adds observability across agents, and ships a new review-focused UI and a faster execution engine. The announcement entry lists these headings without detail.

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.

Hex 4.0 rebuilds projects as code so agents can build them from anywhere.
◆ Current state
Hex is a data workspace whose agent builds projects, Generative Apps and published eval suites, and can be called from the CLI and API. Hex 4.0, now in public beta, makes projects fully code-defined, lets them be built from outside Hex, adds observability across agents, and ships a new review-focused UI and a faster execution engine. The announcement entry lists these headings without detail.
◆ Where it's heading
Since July, Hex has been moving its agent out of the notebook: first callable from the CLI and API, then building whole projects, then metered and tracked. A code-defined project format is the step that lets any agent or editor produce Hex work, with Hex becoming the place people review and run it.
◆ Prediction
Expect the 4.0 beta to be followed by tooling for editing projects as files, such as git sync or editor integrations, and by more agent observability; the entry is too thin to say when general availability lands.
