# Change Log: 2.052

Download D 2.052
released Feb 17, 2011

#### New/Changed Features

- 64 bit support for Linux
- Implemented exception chaining, as described in TDPL. Currently Windows-only.
- std.random: Added Xorshift random generator
- Support HTML5 entities
- Added std.datetime for handling dates and times. std.date and std.gregorian are now scheduled for deprecation. Any functions in other modules of Phobos which used std.date.d_time have been changed to use std.datetime.SysTime or are scheduled for deprecation with new functions with the same functionality added which use SysTime (done in cases where switching existing functions to use SysTime would have broken code). New code should use std.datetime instead of std.date.
- Various functions in std.file were renamed to match Phobos' naming conventions (e.g. isFile instead of isfile). The old names are aliased and scheduled for deprecation.
