-### Pending release
-
-New:
-- New frame change detection algorithm used for [cache determination](https://vladmandic.github.io/human/typedoc/interfaces/Config.html#cacheSensitivity)  
-  based on temporal input difference  
-- New built-in Tensorflow profiling [human.profile](https://vladmandic.github.io/human/typedoc/classes/Human.html#profile)
-- New optional input histogram equalization [config.filter.equalization](https://vladmandic.github.io/human/)  
-  auto-level input for optimal brightness/contrast
-- New event-baseed interface [human.events](https://vladmandic.github.io/human/typedoc/classes/Human.html#events)  
-- New configuration validation [human.validate](https://vladmandic.github.io/human/typedoc/classes/Human.html#validate)  
-- New input compare function [human.compare](https://vladmandic.github.io/human/typedoc/classes/Human.html#compare)  
-  this function is internally used by `human` to determine frame changes and cache validation  
-- New [custom built TFJS](https://github.com/vladmandic/tfjs) for bundled version  
-  result is a pure module with reduced bundle size and include built-in support for all backends  
-  note: **nobundle** and **node** versions link to standard `@tensorflow` packages  
-
-Changed:
-- [Default configuration values](https://github.com/vladmandic/human/blob/main/src/config.ts#L262) have been tuned for precision and performance
-- Supports all built-in modules on all backends  
-  via custom implementation of missing kernel ops  
-- Performance and precision improvements  
-  - **face**, **hand**
-  - **gestures** modules  
-  - **face matching**
-- Fix **ReactJS** compatibility  
-- Better precision using **WASM**  
-  Previous issues due to math low-precision in WASM implementation  
-- Full **TS** type definitions for all modules and imports  
-- Focus on simplified demo
