The current edition of the RCV is r2011. All digital and print versions of the RCV are on the current edition. This edition includes various readability updates throughout the whole text of the RCV.
Beginning in 2014, I have assigned edition numbers to the text of the RCV. This edition number gives the year and month of the release of the text. For instance, the 1401 edition was released in 2014 (14), in the month of January (01). The current edition will always be posted on the Download page on the day of release.
