GGally 2.3.0

• With {ggplot2} v4.0.0, objects are now +'ed together using {S7}. This means the startup message for Registered S3 method overwritten by 'GGally' has been removed. (Thank you @teunbrand for the enhancement in ggplot2! #545)

• Fixed bug where correlations of 0 in a ggcor() output were silently dropped. Now all correlations are always displayed. (Thank you @winterstat! #536)

• Fixed correlations values ggcor() so that they are formatted to the same number of decimal places via label_round. Now 0.2 and 0.001 with label_round = 2 will be displayed as "0.20" and "0.00" respectively. (Thank you @winterstat! #536)

• Added parameter ggally_cor(na.rm=) which is passed directly to ggally_statistic(). (Thank you @vinouselouane! #516)

• Deprecated parameter ggally_cor(use=). The value was never leveraged within the code. Please use ggally_cor(na.rm=) instead. (Thank you @vinouselouane! #516)

• Prepare GGally for {ggplot2} v4 (Thank you @teunbrand! #528)

• Replace internal {plyr} usage with {dplyr}. (Thank you @MichaelChirico! #520, #521, #522, #523, #524, #525, #527, #530)

• General package dependency cleanup. (Thank you @olivroy! #509)

• Fix anyClass ordering in ggparcoord() when data has missing values (Thank you @92amartins! #500)

• Use {lifecycle} for deprecation warnings (Thank you @92amartins! #494, #496)

• Leverage .data$ mask to remove all global variable declarations. (Thank you @MichaelChirico! #533)

• Warn and return "NA" when less than 3 values are given to a combination in ggally_cor(). (Thank you @bk1n! #510)

• Added helper method is_ggmatrix() to check if an object is a ggmatrix object. (#548)

• Remove gg class from ggmatrix objects. This is no longer needed due to enhanced + S7 methods. (#549)

• Bumped minimum required version of R to 4.3 due to S7 handling the + operations. (#549)
