[OSRM-talk] New v5.23.0 release

[Julien Coupey]

Hi Daniel and all

Thanks for your work on this release, and all the various recent 
contributions that made it possible. It's great to see a new OSRM 
version, first one in a long time!

I'd like to ask for a clarification though, if possible, on the status 
of libosrm regarding this new version and possible future ones. There 
are a couple of reports about the API breaking changes ([1] and [2]). It 
means that projects relying on libosrm v5.* no longer compile with 
v5.22, and now v5.23. This is a major problem for downstream users and 
maintainers, especially since the OSRM release process has long been 
adhering to the semver scheme. I only see two ways out:

1. The new v5.23 release somehow endorses the API change (after all a 
fix now would also be a new change from the last two releases). In which 
case downstream users will have to fiddle with adjustments based on 
libosrm minor version.

2. This is considered as something that must be fixed at some point in 
the future. Then no action is required downstream, except stating that 
current libosrm versions are no longer compatible until a patch or new 
minor version is released.

Knowing which option is the most likely would definitely help.
