========
> **Important** : For many years we've used the semantic versioning scheme as defined at http://semver.org. However, in practice, there are external forces (eg clients: artists, producers) who view the major version as a significant milestone rather than a minor ABI break. As a result we've kept the major version at 10 for nearly 3 years now (since Jun 5, 2017), to indicate that we haven't yet fully locked down compatibility on anything.
>
> At IE we've been using Cortex 10 in production for almost 2 years and have rarely (if ever) been bitten by the occasional ABI breaks that have trickled in over that time.
>
> This commit introduces a "milestone" version scheme equivalent to GafferHQ/gaffer. We're setting the current milestone to 10 and bumping the major version to 1, indicating this is indeed an ABI break within the Cortex 10 landscape.
>
> We will now always increment the major version whenever introducing any backwards-incompatible change. We'll bump the milestone version whenever Cortex reaches significant milestones in terms of functionality.
Features
--------
- Build : Improved version numbering scheme (#1058)
- IECore : Added Version.h which provides #defines for the various version parts, a utility macro for composing a compatibility version, version related methods (partially ported from IECore.h), and python bindings for the new methods (#1058)
- Note partial backwards compatibility is provided by including `Version.h` within `IECore.h`
Breaking Changes
----------------
- IECore : Introduced a `milestone` version and decremented `IECore::majorVersion()`. Any conditional logic using the Cortex version (both compile time and runtime) should be updated to accommodate a compatibility version instead.
- The `IECore::*Version*()` methods have move from `IECore.h` to `Version.h` and are now inlined.
