- Changes from 5.20.0
- Features:
- ADDED: all waypoints in responses now contain a distance property between the original coordinate and the snapped location. [Project-OSRM#5255](Project-OSRM#5255)
- ADDED: if `fallback_speed` is used, a new structure `fallback_speed_cells` will describe which cells contain estimated values [Project-OSRM#5259](Project-OSRM#5259)
- REMOVED: we no longer publish Node 4 or 6 binary modules (they are still buildable from source) [Project-OSRM#5314](Project-OSRM#5314)
- Table:
- ADDED: new parameter `scale_factor` which will scale the cell `duration` values by this factor. [Project-OSRM#5298](Project-OSRM#5298)
- FIXED: only trigger `scale_factor` code to scan matrix when necessary. [Project-OSRM#5303](Project-OSRM#5303)
- FIXED: fix bug in reverse offset calculation that sometimes lead to negative (and other incorrect) values in distance table results [Project-OSRM#5315](Project-OSRM#5315)
- Docker:
- FIXED: use consistent boost version between build and runtime [Project-OSRM#5311](Project-OSRM#5311)
- FIXED: don't override default permissions on /opt [Project-OSRM#5311](Project-OSRM#5311)
- Matching:
- CHANGED: matching will now consider edges marked with is_startpoint=false, allowing matching over ferries and other previously non-matchable edge types. [Project-OSRM#5297](Project-OSRM#5297)
- Profile:
- ADDED: Parse `source:maxspeed` and `maxspeed:type` tags to apply maxspeeds and add belgian flanders rural speed limit. [Project-OSRM#5217](Project-OSRM#5217)
- CHANGED: Refactor maxspeed parsing to use common library. [Project-OSRM#5144](Project-OSRM#5144)

Issue
Fixes a problem with distance calculations in
tableresponses (reported in #5306).The reverse offset value in the PhantomNodes was being incorrectly calculated. When this value was used, and the matrix covered only a small distance, it was possible for the incorrect offset to outweigh the distances added to it, and it would end up negative..
