+**5.5.9** *(May 31 20201)*
+- Added configuration option to enable/disable ping failure logging.
+- Fixed a rendering error when the primary historical graph has too many data points.
+- Fixed sqlite3 errors from being ignored (now always logged).
+- Fixed Minecraft session server URL (sessionserver.mojang.com -> session.minecraft.net)
+- Updated to use parcel2
+- Updated various dependencies.
+
 **5.5.8** *(August 1 2020)*
 - Adds daily database copies. This is mostly for use by Minetrack Data for automated exports. By setting `createDailyDatabaseCopy: true` in `config.json`, Minetrack will lazily create a copy of `database.sql` for each day, automatically rolling over to a new file each day. The database file is named in the format of `database_copy_(day)-(month)-(year).sql`. Daily database copies do not contain indexes or previous records. Pings are inserted into the daily database copy as they occur, Minetrack will not retroactively insert previous pings from `database.sql`.
 -  Bump lodash from 4.17.15 to 4.17.19
