Version 0.2.3

• Add allowmissing and disallowmissing convenience functions to convert arrays to support or not support missing values.
• Support one and oneunit.

Version 0.2.2

• Julia 0.7 support.
• Stop exporting deprecated skip method (which was not exported before it was deprecated).

Version 0.2.1

• Deprecate Missings.skip in favor of skipmissing.

Version 0.2.0

• Initial release of the Missings.jl package, identical to Nulls.jl 0.1.2 but with null/Null renamed to missing/Missing, and using ismissing and MissingException.

Version 0.1.2

• Limit zero method to Number and Dates.Period types to avoid turning some MethodErrors to StackOverflowErrors in unrelated packages.
• Add levels function (to use in CategoricalArrays and DataArrays).
• Make Nulls.T(Null) return Union{} rather than Null.

Version 0.1.1

Add rounding and transposition methods.

Version 0.1.0

This release changes the behaviour of comparison operators (==, !=, <, <=, >, and >=), and of logical operators (&, |, xor) to follow three-valued logic, therefore returning null when the result cannot be determined logically. See details in README.md.

Other changes:

• Remove implementation of iteration protocol (breaking change).
• Improve promotion rules.
• Add coalesce function.
• Add Nulls.fail iterator.
• Support bitwise operators with Integer arguments.
• Support zero and !.

v0.0.6

• Discontinue using ?T as synonymous with Union{T, Null}
