# Change Log: 2.030

Download D 2.030
released May 11, 2009

#### New/Changed Features

- added -vtls compiler switch
- classic global storage now defaults to TLS (Thread Local Storage). This is a big change, see Migrating To Shared.
- std.algorithm: added minPos. Improvements to Splitter suggested by Brad Roberts. Splitter now is bidirectional. Also Splitter has one extra trailing element if it ends with a separator. Added variadic arguments for setUnion and setIntersection. Added functions setSymmetricDifference and largestPartialIntersection. Improved BinaryHeap's interface and implementation.
- std.array: Improvements to Appender. Now it works with string and other immutable-element arrays, and accepts ranges in put().
- std.format: added raw specifier for reading
- std.range: Added iota with two arguments. Added FrontTransversal and Transversal.
- std.stdio: added File.byChunk
- std.traits: Added isImplicitlyConvertible.
- std.tuple: Added Tuple.opComp.
- Folded in compiler changes by Unknown W. Brackets to support Solaris.
- added .typeinfo to ClassInfo Bugzilla 2836: Navigate from ClassInfo to TypeInfo
