patchwork 1.1.3

NULL can now be used with the different arithmetic operators and will result in a non-operation (i.e. the non-null part will be returned unmodified) (#290)
Fix a bug that prevented plots with multi-level strips from being merged together (#277)
Patchworks will now render correctly when unserialised in a fresh session, providing the patchwork package is available (#242)
Fixed a bug preventing faceted plots with strip placement outside the axis from being aligned (#325)
Fixed a bug that let to inconsistent results when combining fixed aspect plots in different order (#274)
Fixed a bug that prevented nested patchworks with empty columns or rows at the bottom or to the right to be inserted into a layout (#273)
Patchwork objects now behaves more correctly like an unnamed list of ggplots. This makes View() work on them (#317), and allow one to use length() to determine the number of patches in a patchwork (#293)
Expressions and calls can now be used as plot annotations in the same way as they can be used for titles in ggplot2 (#295)

Avoid incrementing tag counter when recursing into a nested plot without additional tags to use (#147)
Fix bug that prevented strips turned off with element_blank() from working (#200)

Renaming of align_plots() to align_patches() to avoid namespace clash with cowplot (#130)
Renaming of as_grob() (unexported) to as_patch() to avoid potential future namespace clash with cowplot (#131)
Fix bug in plot simplification with theme(strip.placement = 'outside') (#132)
Fix a bug in guide collection in R >= 4.0 due to the new unit implementation in grid (#170)
Collected guides now behave as ggplot2 guides when position is top or bottom (#137)
Fix a bug in base graphic support where the environment of the plot was not captured (#138)
Fix a bug when combining plots having guides placed manually in combination with faceting (#144)
Fix a bug where having negative margins around the legend would result in an unintelligeble error (#148)
Fix a bug when trying to combine faceted plots with fixed aspect ratio (#156)
Fix alignments of strips when only a single strip is present (#163)
Fix a bug that caused theme void to result in errors (#180)
Make aligning multiple fixed aspect plots more consistent (#175)
Correct alignment of guides when ssembling fixed aspect plots (#140,

First CRAN release. Provide utility and operators for assembling and nesting plots into a composition, tag subplots, collect guides and remove duplicates, and align plots across pages.
