• Cache::has() now properly checks TTL expiration before returning true (PSR-16 compliance fix). Previously, has() returned true for expired items.

• Cache::has() now deletes expired items on check (lazy cleanup, consistent with get() behavior).

4.8.09

• sha1 is now the default fn for encoding cache keys. Using base64 was causing problems in Laravel.

4.8.03

• added optional $config to MobileDetect constructor.
• added autoInitOfHttpHeaders configuration which is by default true. This enabled the old behavior from 3.x and 2.x that allows automatic detection of HTTP headers and User Agent from $_SERVER.
• refactored internal CloudFront related methods and the way setHttpHeaders work. It no longer falls back on $_SERVER. The method still calls setUserAgent in case HTTP_USER_AGENT and friends are present.
• added maximumUserAgentLength to the $config, by default the limit is 500.

• regexes can be arrays of strings or strings

2023

Launched 4.8.xx which contains PHP 8.x support, refactorings and external Cache support.

• Cache::evictExpired() method to manually clean up expired cache entries. Useful for long-running processes (CLI scripts, workers, daemons) to prevent memory growth.

2012

Throughout 2012 the script has been updated constantly, and we have received tons of feedback and requests. In July 2012 we moved the repository from Google Code to GitHub in order to quickly accommodate the frequent updates and to involve more people.

In December 2011 it received a major update from the first version, an important number of issues were fixed, then 2.0 was launched. The new version marks a new mindset and also featuring tablet detection.

The first version of the script was developed in 2009, and it was hosted at https://code.google.com/p/php-mobile-detect/, it was a small project with around 30 stars. (Original blog post by Victor: http://victorstanciu.ro/detectarea-platformelor-mobile-in-php/)
