What is Fairing?

Fairing extends beyond on-site surveys into delivery, analytics, and integrations.

Fairing's recent releases spread across three areas: new survey delivery (a hosted, branded landing page and email sends), analytics depth (period-over-period comparisons), and integration hygiene (Klaviyo OAuth, API filtering, upcoming rate limits). The core post-purchase survey product is being extended outward toward reporting and distribution.

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.

5.0

Fairing extends beyond on-site surveys into delivery, analytics, and integrations.

◆ Current state

Fairing's recent releases spread across three areas: new survey delivery (a hosted, branded landing page and email sends), analytics depth (period-over-period comparisons), and integration hygiene (Klaviyo OAuth, API filtering, upcoming rate limits). The core post-purchase survey product is being extended outward toward reporting and distribution.

◆ Where it's heading

The direction is from a single on-site survey widget toward a fuller attribution-and-feedback platform: more ways to deliver surveys, richer in-app analytics, and tighter ties to the ecommerce and marketing stack. API governance (rate limits, OAuth) signals a maturing platform with real third-party consumers.

◆ Prediction

Expect more delivery surfaces and analytics comparisons, plus deeper destination integrations that push Fairing response data into tools teams already use.

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.
