gganimate 1.0.9

• Fix for using "svg" device during knitting (#484)
• Fix for correctly getting chunk options during knitting (#485)
• Fix a bug in transition_reveal() that would remove data during transitions
  (#480 and #473)
• General upkeep to keep it in line with the evolvling coding principles in
  ggplot2 (move to using vctrs, cli, lifecycle, etc)
• transition_reveal() now throws an error when it is used in conjunction with
  stat_align() and transitioning before the stat has been calculated (#476)
• Label interpolation now works when labels are expressions (#439)
• as_html_video() gains muted, loop, and controls argument to control
  presentation of the video. Like autoplay these can be controlled during knitr
  through the chunk options (e.g. gganimate = list(muted = TRUE, loop = TRUE))
  (#444)
• Make the build process up-to-date with ggplot2 3.5.0

gganimate 1.0.8

• Fix a bug when creating labels from aesthetics that include glue expressions
  (#422)
• Fix a bug in ffmpeg detection (#346, @rfaelens, #360, @adamdsmith)
• Remove plyr dependency
• Fix a bug in transition_filter() in the presence of NA filter values
  (#404, @rsaporta)
• Fix a bug with static layers that include position adjustments (#418)
• Fix a bug in transition_time() where multiple time values in the same frame
  would lead to unexpected stacking of the data (#414)
• Fix a bug in transition_reveal() where coinciding tweens would result in
  wrong direction of the arrow (#409)
• Fix a bug in transition_layer() when the last layer had an exit duration
  (#384)
• Fix a bug in transition_time() when facets had data with different starting
  time (#357)
• Make sure exclude_layer in view_*() is taken into account
• Fix a bug when using a view with coord_flip() which would result in weird
  flickering and movement of the position guies (#336)
• Fix a bug in transition_reveal() that would require input to be ordered
  along the time dimension for point-like geoms (#323)
• Fix a bug in view_follow() that would result in errors when used with
  discrete scales (#304)
• Fix bug in transition_states() where too few frames relative to states in
  combination with wrap = FALSE would cause an error (#301)
• Fix a bug in transition_time() when the time dimension contained NA values
  (#307)

  interpreted as a double (#266)
• Fix bug in shadow_mark() where future shadows were drawn above the main
  frame data.
• Better error messages when a layer type is not supported by the transition
• Fix bug where transitions didn't work with difftime/hms for specifying
  durations when transition variable was a POSIX or date class.
• Fix bug where using a view would modify the plot coordinate system in-place,
  resulting in modifications to the original plot object.
• view_follow now works with transformed scales.
