Traccar 4.0

August 5, 2018

Version 4.0 of Traccar GPS tracking platform is available for download.

The first point I want to address is the reason behind the major version update. The Traccar device communication layer is heavily based on the Netty network library (originally developed by JBoss). For a long time we have used outdated versions 3.x of the library, which are not updated anymore. With this release we upgraded Traccar to use the latest version 4.x of Netty. Along with many smaller improvements and bug fixes, it should bring us better performance. The drawback is that it caused extensive code changes for all protocols and might not be as stable at first.

Other notable features and improvements in this release:

• Keep track of engine hours in the same way we calculate distance on the server
• Renamed all database tables to avoid conflicts with reserved keywords (specifically new versions of MySQL)
• Removed old network library that we used for HTTP requests, which was using Netty 3 under the hood
• Fixed problem with queued commands from server to devices

As usual there were a lot more smaller improvements and bug fixes, including a fix to the report exports.

New protocols in Traccar 4.0:

• Wialon Retranslator - software from Gurtam
• Svias - GPS tracker manufacturer from Brazil
• eSeal - smart container and door locks from S-Winnus
• Freematics - open source ODB-2 GPS devices
• Avema - GPS units vendor from Taiwan
• AutoTrack - GPS services company from Bulgaria
• Tek - Remote sensors vendor from Tekelek

This release might not look so big from the end user point of view, but from the development side it's one of the biggest releases and affects all supported protocols.
