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.

ntopng 7.0 adds an AI traffic analyst, Wazuh integration and BGP in one release.

◆ Current state

ntopng 7.0 arrived in September, ten months after 6.6. nAnalyst brings AI chat, policies, dashboards and an agentic loop across multiple LLM providers, with an MCP server included. The release also adds Wazuh XDR/SIEM integration, a Sites hierarchy, BGP/BMP with RPKI validation, a ClickHouse timeseries engine, OpenID Connect SSO, MFA and passkeys, and a new Vue.js frontend replacing legacy pages.

◆ Where it's heading

Each major has annexed an adjacent category, and 7.0 reaches for three at once: AI-assisted analysis, SIEM-adjacent security and routing visibility. ClickHouse is now the assumed foundation, and nAnalyst requires it. The licensing line is also explicit, with nAnalyst limited to enterprise M and above and the MCP functions split between community and pro.

◆ Prediction

Point releases should focus on nAnalyst and the new frontend, the two largest and least mature surfaces. The next major, on past spacing, is about a year off and likely extends the same analysis and security surfaces.

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.
