Today, we released the March 2019 Update.

Quality and Reliability

This release contains the following quality and reliability improvements.

CLR

  • Addresses an issue in which the Framework throws an exception if the year in the parsed date is greater than or equal to the start year of the next era. Now, the framework will not throw such exception. [603100]
  • Updates Japanese Era dates that are formatted for the first year in an era and for which the format pattern uses the “y年” characters. The format of the year together with the symbol “元” is supported instead of using year number 1. Also, formatting day numbers that include “元” is supported. [646179]
  • Allows the output of Gannen characters in Japanese Era formatting of first year dates regardless of whether the format pattern includes single quotation marks around the “年” character. [777182]
