yaml-cpp/docs/Breaking-Changes.md

The following is a list of breaking changes to yaml-cpp, by version

New API

HEAD

• Throws an exception when trying to parse a negative number as an unsigned integer.
• Supports the as<int8_t>/as<uint8_t>, which throws an exception when the value exceeds the range of int8_t/uint8_t.

0.6.0

• Requires C++11.

0.5.3

none

0.5.2

none

0.5.1

• Node::clear was replaced by Node::reset, which takes an optional node, similar to smart pointers.

0.5.0

Initial version of the new API.

Old API

0.3.0

none

0.2.7

• YAML::Binary now takes const unsigned char * for the binary data (instead of const char *).

0.2.6

• Node::GetType() is now Node::Type(), and returns an enum NodeType::value, where:

struct NodeType { enum value { Null, Scalar, Sequence, Map }; };

• Node::GetTag() is now Node::Tag()
• Node::Identity() is removed, and Node::IsAlias() and Node::IsReferenced() have been merged into Node::IsAliased(). The reason: there's no reason to distinguish an alias node from its anchor - whichever happens to be emitted first will be the anchor, and the rest will be aliases.
• Node::Read<T> is now Node::to<T>. This wasn't a documented function, so it shouldn't break anything.
• Node's comparison operators (for example, operator == (const Node&, const T&)) have all been removed. These weren't documented either (they were just used for the tests), so this shouldn't break anything either.
• The emitter no longer produces the document start by default - if you want it, you can supply it with the manipulator YAML::BeginDoc.

0.2.5

This wiki was started with v0.2.5.
