Guzzle 7 Released

Guzzle 7 Released

The popular Guzzle HTTP client reached version 7 last week, with the exciting news that most users (the changelog says 95% of users) will be able to upgrade without modification. This release focused on increasing the minimum supported PHP version and introducing new language features found in PHP 7.

The main features of the 7.0 release include:

  • Implement PSR-18
  • Dropped PHP 5 support—the minimum PHP version is now 7.2
  • Type hints and return types for functions and methods have been added whenever possible
  • IDN support for redirects (see #2424 for details)

Be sure to check out the 6.0 to 7.0 upgrade guide for a list of known backward compatibility breaking changes with 6.x.

One update I found of note was client HTTP methods (i.e., get, post, etc.) with strong typing:

The get, head, put, post, patch, delete, getAsync, headAsync, putAsync, postAsync, patchAsync, and deleteAsync methods are now implemented as genuine methods on GuzzleHttp\Client, with strong typing. The original __call implementation remains unchanged for now, for maximum backward compatibility, but won’t be invoked under normal operation.

If you still need to access the v6 documentation and otherwise may need to use both Guzzle 6 and 7, check out the version guidance table in the project’s readme. At the time of writing, the latest docs have “Guzzle 6” in the heading, but docs.guzzlephp.org/en/latest/ are the Latest Guzzle 7 docs.
