# Change Log: 2.059

Download D 2.059
released Apr 12, 2012

#### New/Changed Features

- Add predefined Ddoc macro SRCFILENAME
- Changed lexer to support # as a token, preserving #line's original behavior
- added AES, PCLMULQDQ, RDRAND, AVX, VAES, VPCLMULQDQ, FMA, FP16C to core.cpuid
- Bugzilla 435: Constructors should be templatized
- Bugzilla 2367: Overloading error with string literals
- Bugzilla 3382: [tdpl] Implement uniform function call syntax
- Bugzilla 4536: Typetuples (T...) should have an .init member
- Bugzilla 5525: Eponymous templates should allow for overloaded eponymous members
- Bugzilla 7105: relax inout rules
- Bugzilla 7833: Changelog should clearly mention struct literal/opCmp/opEquals/toHash changes
- Strive to make toHash, toString, opEquals and opCmp functions pure, nothrow, const and @safe. Soon, this will become a requirement.
- The deprecated std.date, std.dateparse, and std.gregorian modules have been removed. Please use std.datetime instead.
- Several deprecated functions in std.file have been removed.
- The old functions in std.path which were scheduled for deprecation have now been deprecated. Please use the new ones which were introduced in 2.055. However, note that curdir and pardir do not have replacements, because they're "." and ".." respectively on all OSes so variables for them were seen as unnecessary. Also, one major change to note about the new std.path functions is that when operating on extensions, they expect "." to be part of the extension whereas the old ones did not (e.g. "file.txt".extension == ".txt" whereas "file.txt".getExt() == "txt").
- The version of std.exception.enforceEx which was scheduled for deprecation has been deprecated. Please use the version which takes exceptions which can be constructed with new E(msg, file, line) (rather than just new E(msg) as the old version did). That way, exceptions constructed with enforceEx will give the file and line number where enforceEx was called.
- Get rid of Win9x support.
- std.typecons: Added Proxy mixin template.
- std.format: Added documentation about compound format specifier.
