Dear OSRM community,

I am excited to announce the release of OSRM v0.4.3 [1], your favorite OpenStreetMap based routing engine. We are moving at a fast pace and are combining nearly 193 commits (85 files changed, 4,157 additions and 2,276 deletions) this time. This release brings a number of exciting changes!

This is the shortened change log:

- Announcement of waypoints, closes #584
- U-Turns at Via nodes are now allowed (not yet visible in frontend)
- Extraction of road network roughly 10% faster than previous release
- No inconvient use of space in /tmp anymore
- Added a distinct tool to check if hsgr file is valid: osrm-check-hsgr
- Added more unit tests based on boost/test.
- Use multiple cores during sorting steps
- Windows port much more stable, builds with significantly less errors

- Fixed a rare segfault in path query
- Fixed a bug in turn restriction combination including overlaps and one-ways
- Fixed bug in osrm-components tool
- Added timings to a number of locations
- Added BUILD_TOOLS cmake flag, deprecated WITH_TOOLS
- Fixed selection of alternative route name
- Many, many bigger and smaller code changes

Potentially breaking changes:
- bumped minimum GCC version to 4.8
- the projects git repository has been moved [2]

Please note that the minimum supported GCC version is now 4.8. As always, we are dog-fooding our releases and the code of v0.4.3 is already running on our demo site [3] for several days without issues. The v0.4.x release series continues to focus on new features and significate efficiency improvements. Big thanks to everyone who contributed to this important milestone release!
