Guzzle is a very popular library to make PHP requests. As many MODX extras use it, they're at risk of causing conflicts when different versions are used at the same time.
Instead of coupling a specific version of Guzzle with their packages, this meta package will install the latest version and make it available globally. Learn more.
After installation, Guzzle will be available and autoloaded for packages to use.
For instructions on adapting your packages to use it, please see the GitHub readme.
