_subsection: BigNumber

|
_heading: Namespace
|
||
|
|
Since [[bignumber]] is used quite frequently, it has been moved to
|
||
|
|
the top level of the umbrella package.

|
_heading: Creating Instances
|
||
|
|
The ``bigNumberify`` method was always preferred over the constructor
|
||
|
|
since it could short-circuit an object instantiation for [[bignumber]
|
||
|
|
objects (since they are immutable). This has been moved to a static
|
||
|
|
``from`` class method.

_subsection: Errors
|

|
|
|

|
|
_heading: Namespace
|
||
|
|
All errors now belong to the [[logger]] class and the related functions
|
||
|
|
have been moved to [[logger]] instances, which can include a per-package
|
||
|
|
version string.
|
||
|
|
|
||
|
|
Global error fucntions have been moved [[logger]] class methods.

_subsection: Interface
|
||
|
|
The [[abi-interface]] object has undergone the most dramatic changes.
|
||
|
|
|
||
|
|
It is no longer a meta-class and now has methods that simplify handling
|
||
|
|
contract interface operations without the need for object inspection and
|
||
|
|
special edge cases.

||

|
_heading: Inspection
|
||
|
|
Interrogating properties about a function or event can now (mostly) be
|
||
|
|
done directly on the [[abi-fragment]] object.

_heading: Mnemonic Phrases
|

|
|
The **mnemonic** phrase and related properties have been merged into
|
||
|
|
a single ``mnemonic`` object, which also now includes the ``locale``.
