4.0.0

SC_API_VERSION 14.0.0

This is the initial release of SeisComP under a new license and with a new
versioning scheme. Instead of using a release name and a time based version
tag semantic versioning is now being used with a sequence of three digits:
Major.Minor.Patch. The following rules apply for assiging a new digit:

• Major: Libraries introduce binary incompatible changes or there are very
  significant application changes which justify a major version
  bump.
• Minor: Libraries add new functionality and methods but binary
  compatibility within the same major release is still maintained
  with application built against a lower minor version. Significant
  application changes can also justify a minor version bump.
• Patch: No changes in functionality but error corrections of existing
  codes.

Breaking changes:

• Spread has been replaced as messaging system with our own implementation
  of a messaging broker. That means that connections between SeisComP3 and
  SeisComP >= 4.0.0 are not possible until a driver has been developed
  which implements Spread in SeisComP or scmp in SeisComP3.
• Qt5 and Python3 are now supported preferred.
• The SeisComP Python packages have been renamed to seiscomp but a
  compatibility layer for seiscomp3 has been added.
• Arclink is no longer supported and has been removed completely.
• arclinkproxy has been removed as well and is superseded by scwfas.
• The installation directory is now seiscomp and not seiscomp3.
• The user configuration directory is now .seiscomp and not .seiscomp3.
• C++ compilation requires a compiler that supports at least the C++11
  standard.
