# ReliaGrowR 0.8

## New Features
* New `gof()` function for computing numerical goodness-of-fit statistics
  (Cramér-von Mises and Kolmogorov-Smirnov) for fitted RGA models.
* New `predict_duane()` function for making predictions from Duane models,
  with confidence bounds and `print`/`plot` S3 methods.
* New MCP server integration via `rga_mcp_server()`, exposing ReliaGrowR
  functions as Model Context Protocol tools for AI assistants such as Claude.

## Minor improvements and bug fixes
* New vignette on Reliability Demonstration Test Planning.
* New vignette on MCP server usage.

* Other minor improvements and bug fixes.

# ReliaGrowR 0.6

## New Features
* New `nhpp()` function for fitting parametric Non-Homogeneous Poisson Process (NHPP) models (Power Law and Log-Linear) to recurrent event data from repairable systems, including piecewise/segmented support with automatic change point detection.
* New `mcf()` function for non-parametric Mean Cumulative Function estimation using the Nelson-Aalen estimator.
* New `exposure()` function for computing system exposure (total operating time at risk) across repairable systems.
* New `overlay_rga()` and `overlay_nhpp()` functions for overlaying multiple model fits on a single plot.
* New hex sticker logo for the package.
