* fix for new data.table version (issue #67). Thanks to John Williams.
* fix dplyr behaviour (issues #65, #68)

0.10.5 (05.07.2020)

* fixes for new versions of R, htmlTable, huxtable

0.10.3 (30.03.2020)
================
* very minor fix: revert back default method for 'set_caption'

================
* fixes for R4.0
* new vignette with examples
* add functions 'hide' and 'unhide' for selective hiding and showing categories in 'net' and 'subtotal'
* now logical don't have special meaning in the 'recode'. If you use this functionality than use 'when' instead. 
    recode(y, x>5 ~ 1) need to be replaced with recode(y, when(x>5) ~ 1).
* add 'xl_write_file' for quick export tables to Excel file
* Add 'tab_caption' - alias for 'set_caption'

0.10.1 (28.11.2019)
================
* output to PDF, Word via huxtable package (thanks to Sebastian Jeworutzki). See 'as_hux' and 'expss_output_huxtable'.   
* bugfixes

0.9.1 (26.08.2019)
================
* fix vignette for new 'reformulate' 
* fix recode for list recodings. Now c(1, 5 %thru% 99) ~ 999 works properly.
* 'subtotal' and 'net' produce consistent ordering of subototal items (thanks Roberto Gilsaura for extensive testing)
* 'subtotal' and 'net' allow overlapping categories

0.9.0 (01.07.2019)
================
* add 'subtotal' and 'net' functions. See '?net'.
* 'recode' now can recode value labels to keep them consistent with values (see argument 'with_labels')
* add alias 'rec' to recode with argument 'with_labels = TRUE' by default
* now you can assign new labels in 'recode' ("TOP" = 4:5 ~ 5)
* improve 'recode' performance
* simplify 'recode' behavior. Now RHS and LHS part in the recoding formula should be single column object. However, you can still recode entire data.frame or list.
* improve preformance of 'sum_row', 'mean_row', 'median_row' and etc.
* change labelled 'csv' format. Now labels are stored in the same file as data. Labels are located in the commented lines at the begining of the file. Ispite of changing format, 'read_labelled_csv' should detect and read the old format automatically.
* add new functions: 'read_labelled_xlsx' and 'write_labelled_xlsx'. Now you can save and restore labelled data to Excel file. Labels are stored on the separate sheet. 
* add new functions: 'read_labelled_fst' and 'write_labelled_fst' for storing data in the 'fst' format (https://www.fstpackage.org/). With this format you can read and write a huge amount of labelled data very quickly.
* Small bugfixes.
