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 Sprig?
Sprig is layering AI agents on top of every step of the survey pipeline.
Sprig has spent six months turning surveys into an AI-augmented research pipeline. November opened with Conversational Surveys and MaxDiff. Q1 added Attribute Piping for personalization, Display Logic on Enterprise, AI Follow-up Question for adaptive probes, and prototype testing improvements. April delivered AI Dynamic Questions and the Synthesize Agent's AI Study Report. Two distinct threads run in parallel: classic survey-tooling depth, and named AI agents that handle the parts humans used to.

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.
Sprig
3.8ANALYTICS
Sprig is layering AI agents on top of every step of the survey pipeline.
◆ Current state
Sprig has spent six months turning surveys into an AI-augmented research pipeline. November opened with Conversational Surveys and MaxDiff. Q1 added Attribute Piping for personalization, Display Logic on Enterprise, AI Follow-up Question for adaptive probes, and prototype testing improvements. April delivered AI Dynamic Questions and the Synthesize Agent's AI Study Report. Two distinct threads run in parallel: classic survey-tooling depth, and named AI agents that handle the parts humans used to.
◆ Where it's heading
The product is moving from a survey runner to an end-to-end research workflow with agents at the question, response, and analysis layers. Enterprise gating shows up consistently on the AI features, signaling that AI is the upsell. Expect more named agents (segmentation, recommendation, trend tracking) and tighter ties between agent outputs and product analytics.
◆ Prediction
The next directional move likely connects agent insights back into product surfaces and growth experiments, closing the research-to-action loop. AI Dynamic Questions and Display Logic should converge into a single adaptive-flow primitive available beyond Enterprise.
