Update for changes in R namespace best-practices.
New parameter .id to adply() that specifies the name(s) of the index column(s). (Thanks to Kirill Müller, #191)
Fix bug in split_indices() when n isn't supplied.
Fix bug in .id parameter to ldply() and rdply() allowing for .id = NULL to work as described in the help. (Thanks to Doug Mitarotonda, #207, and Marek, #224 and #225)
Deprecate exotic functions liply() and isplit2(), remove unused and unexported functions dots() and parallel_fe() (Thanks to Kirill Müller, #242, #248)
Warn on duplicate names that cause certain array functions to fail. (Thanks to Kirill Müller, #211)
Parameter .inform is now honored for ?_ply() calls. (Thanks to Kirill Müller, #209)

New parameter .id to ldply() and rdply() that specifies the name of the index column. (Thanks to Kirill Müller, #107, #140, #142)
New parameter .id to rdply() that specifies the name of the index column. (Thanks to Kirill Müller, #142)
The .id column in ldply() is generated as a factor to preserve the sort order, but only if the new .id parameter is set. (Thanks to Kirill Müller, #137)
rbind.fill now silently drops NULL inputs (#138)
rbind.fill avoids array copying which had produced quadratic time complexity. *dply of large numbers of groups should be faster. (Contributed by Peter Meilstrup)
rbind.fill handles non-numeric matrix columns (i.e. factor arrays, character arrays, list arrays); also arrays with more than 2 dimensions can be used. Dimnames of array columns are now preserved. (Contributed by Peter Meilstrup)
rbind.fill(x,y) converts factor columns of Y to character when columns of X are character. join(x,y) and match_df(x,y) now work when the key column in X is character and Y is factor. (Contributed by Peter Meilstrup)
Fix faulty array allocation which caused problems when using split_indices with large (> 2^24) vectors. (Fixes #131)
list_to_array() incorrectly determined dimensions if column of labels contained any missing values (#169).
r*ply expression is evaluated exactly .n times, evaluation results are consistent with side effects. (#158, thanks to Kirill Müller)
