-applicable 0.0.1.1
-==================
+# applicable (development version)
+
+- Improved `autoplot.apd_pca()` selector handling to fail early with a clear error when `...` selectors match no columns.
+- Modernized package code, tests, and vignettes to use base R pipes (`|>`) and replaced superseded tidyverse helpers (`pivot_longer()`, `across()`, and `rename_with()`).
+- Updated tests to use stricter modern expectations, including replacing success-path `expect_error(..., regexp = NA)` checks with `expect_no_error()`.
+- Expanded isolation-method maintenance and coverage work, including formula-interface checks, `check_isotree()` test paths, and refreshed isolation `.Rd` documentation.
+- Added a helper script (`scripts/test-changed-functions.R`) to report changed functions, check test references, run testthat, and run `covr` coverage for changed code.
+- Improved CRAN/release readiness with additional housekeeping: build ignore updates for `scripts/`, version/roxygen metadata maintenance, link/DOI and vignette compliance fixes, plus spelling/WORDLIST updates.
+- Included prior plotting/printing refinements: PCA plot sizing/faceting and print-method formatting cleanups.
+- Updated Quarto vignette chunk options to in-body YAML style and bumped package version in `DESCRIPTION` to `0.2.1`.
+- Switched Ames dataset documentation links from `http` to `https` in source, vignette text, and generated `.Rd` docs.
+- Refreshed website/project assets and configuration files (including favicon assets and editor/project config updates).
+
+# applicable 0.1.1
+
+
+- Changes in [apd_isolation()] because [isotree::isolation.forest()] changed their default for the number of dimensions to 1. 
+
+- Updated snapshot unit tests that changed from rlang's changes related to the call/traceback. 
+
+# applicable 0.1.0
+
+
+Added isolation forest methods via the isotree package in the function `apd_isolation()`.
+
+# applicable 0.0.1.1
+
 
 Minor patch release: fixed failing units tests due to recent package updates.
