-# UNRELEASED

   - Changes from 5.19.0:
     - Table:
       - CHANGED: switch to pre-calculated distances for table responses for large speedup and 10% memory increase. [#5251](https://github.com/Project-OSRM/osrm-backend/pull/5251)
+      - ADDED: new parameter `fallback_speed` which will fill `null` cells with estimated value [#5257](https://github.com/Project-OSRM/osrm-backend/pull/5257)
+      - CHANGED: Remove API check for matrix sources/destination length to be less than or equal to coordinates length. [#5298](https://github.com/Project-OSRM/osrm-backend/pull/5289)
+      - FIXED: Fix crashing bug when using fallback_speed parameter with more sources than destinations. [#5291](https://github.com/Project-OSRM/osrm-backend/pull/5291)
     - Features:
       - ADDED: direct mmapping of datafiles is now supported via the `--mmap` switch. [#5242](https://github.com/Project-OSRM/osrm-backend/pull/5242)
       - REMOVED: the previous `--memory_file` switch is now deprecated and will fallback to `--mmap` [#5242](https://github.com/Project-OSRM/osrm-backend/pull/5242)
+      - ADDED: Now publishing Node 10.x LTS binary modules [#5246](https://github.com/Project-OSRM/osrm-backend/pull/5246)
     - Windows:
       - FIXED: Windows builds again. [#5249](https://github.com/Project-OSRM/osrm-backend/pull/5249)
