As we step into 2025, the future has never looked brighter for us at 51Degrees. But before we unveil some thrilling news, let’s take a moment to reflect on our journey through 2024.

The UK bank holidays will affect our data file and support availability. This blog details key dates for 2024-2025.

Calling probabilistic identifiers implies wrongdoing, but sharing such data isn’t illegal unless it's used to make impactful decisions about individuals.

The new 51Degrees IsArtificialIntelligence property helps identify whether a web crawler is being used to gather data for AI training. This property gives the user greater control and can be used to block certain crawlers from accessing content, particularly when AI training doesn't serve their interests.

A lot happened in 2023 – industry changes and major device releases dominated the device detection market. In response to this, we continuously updated the 51Degrees service.

We’ve retired the HAProxy git.51degrees.com service. We recommend you get started with Version 4 which retains features such as in-memory data upgrades and multi-threading support.

We’ve updated our predictive algorithm to tolerate corruption in the User-Agent and User-Agent Client Hints data. The changes result in a more accurate device detection.

In the next round of device detection improvements to 51Degrees, we’ve improved our data file release schedule.

We’ve improved our device detection accuracy following feedback raised by our customers, and we’re pleased to announce the release of our upgraded algorithm and data files.
