 ## User-Facing Changes from Previous Versions 
@@ -40,11 +41,19 @@
 * Function `wl_convert_units()` converted into S3 generic. Default and hyperSpec methods were added (#29).
 * Dataset `faux_cell` and function `generate_faux_cell()` replace `chondro` dataset (cbeleites/hyperSpec#125, cbeleites/hyperSpec#156, cbeleites/hyperSpec#180, cbeleites/hyperSpec#229).
 * Documentation aliases have been updated. Now, ?hyperSpec points to the function `hyperSpec()`, and to refer to the package, `package?hyperSpec` should be used (#129).
+* Vignette `hyperSpec.Rmd`: suggested packages (`pls`) are now loaded conditionally so the vignette builds even when they are not installed.
+
 
 ### Bugfixes
 
 * Possibility to initialize `hyperSpec` object by providing wavelengths only (cbeleites/hyperSpec#288).
 * Column names in spectra matrix (`$spc` column of `hyperSpec` object) are now returned correctly by functions `spc.bin()` (cbeleites/hyperSpec#237), and `spc.loess()` (cbeleites/hyperSpec#245
+* `all.equal()` method for `hyperSpec` objects converted from S4 to S3 registration. The S4 `setMethod()` approach for this S3 generic caused roxygen2 (>= 7.3) to crash during documentation generation.
+* `rbind.fill()` (internal): strip the `AsIs` class from matrix columns after data frame assembly. R >= 4.4 introduced `all.equal.AsIs()` which caused spurious class-mismatch failures when comparing `hyperSpec` objects that had been through `rbind` or `collapse`.
+* `wl_create_label_from_units()`: fixed incorrect use of `grep()` where `sub()` was intended, which caused malformed wavelength axis labels for units containing `"_greek"`.
+* `collapse()`: correctly sorts wavelengths in the merged result and preserves expected row order when combining `hyperSpec` objects with differing wavelength axes.
+* Fixed Rd cross-references for `levelplot()` in `plot_matrix` and `map.sel.poly` documentation to include `lattice` package anchor.
+* Vignette `hyperSpec.Rmd`: suggested packages (`pls`, `baseline`, `mvtnorm`, `colorspace`) are now loaded conditionally so the vignette builds even when they are not installed.
