Some new dimensions, units, several bug fixes related to Julia 0.7 upgrade.

Release passing on 0.7-rc1 and nightly.

Release passing on 0.7-beta2 and nightly.

First release requiring / compatible with julia 0.7-beta.

See NEWS.md for further information.

Bug fixes, mainly.

See NEWS.md for details.

- Permit symbols that are bound to `Number`s to be used in `u_str` macro, such that `π` and other non-literal numbers can be used. - Add some cgs units and a few dimensions #115. - Fix a comparison / promotion bug introduced in v0.6.0.

Fixes to get Unitful working on 0.7.0-DEV again (bump minor version for Compat requirement).

See NEWS.md for details.

See NEWS.md for changes.

Introduce logarithmic scales and quantities (experimental). See NEWS.md for other changes.

- Require Julia 0.6 - Adds overloads for `rand` and `ones` [#96](https://github.com/ajkeller34/Unitful.jl/issues/96). - Improve symbol resolution in `u_str` macro [#98](https://github.com/ajkeller34/Unitful.jl/pull/98). - More work is done inside the `u_str` macro, such that the

Bug fix; implement Base.rtoldefault for quantity types.

Bug fixes and minor feature additions.

Bug fixes.

Restore two broken tests; fix design problems with `floor`, `ceil`, `round`, `trunc`, `isinteger`

Bug fix release.

Fixed `isapprox` bug and added `DimensionlessQuantity` methods for `exp`, `exp10`, `exp2`, `expm1`, `log1p`, `log2`.

`Units{N,D}` is now an abstract type. Different concrete types for units give different behavior under conversion and promotion, enabling predictable behaviors for package development that don't necessarily depend on mutable user preferences. For details, see NEWS.md, as well as

Bug fixes and UX improvements.

Bug fix release.

See NEWS.md or the Unitful documentation for release details.

On Julia 0.6, exponentiation by a literal is now type stable for integers.

See NEWS.md or the Unitful documentation for release details.

Fix a macro hygiene issue and add tests for expected functionality of the macros that define new units and dimensions.
