For more information, please see ### Changelog [](#changelog) - **4.1.0** - Added `alwaysReturnUpdate` property to optionally return update metadata with a 200 status even when license validation fails (empty `download_url`). - **4.0.2** - Minor change to function param signature to support PHP 8+ - **4.0.1** - Fixes a bug with license validation from domain details being sent via the POST body instead of the query string. - **4.0.0** - Merges 1.5 years of upstream improvements and removes the naming collision work that was introduced in 3.1.0. The package now supports scoping with [PHP Scoper](https://github.com/humbug/php-scoper) to prevent naming collisions. You will need to change your Kernl instantiation from `Puc_v4_FactoryKernl` to `Puc_v4_Factory`. - **3.1.0** - Changes instantiation to prevent naming collisions. - **3.0.1** - Fixes a PHP notice that was accidentally introduced in version 3.0.0 - **3.0.0** - Refactored to prevent naming collisions with other plugins/themes that may use the un-modified version of the PUC library. Removed dead code. - **2.6.0** - Update check requests now use POST instead of GET. When Kernl Analytics is enabled it is possible to send a querystring larger than is allowed on some servers. This resolves the issue by sending the data as an HTTP POST body. - **2.5.0** - Adding support for capturing MySQL/MariaDB version for Kernl Analytics. - **2.4.0** - Adding some additional error logic so a fatal error will not be triggered if Kernl is down for some reason or a request fails. - **2.3.0** - Added `admin_notice` when the update check fails due to an invalid license. - **2.2.0** - Initial version published to Packagist. ### Health Score 53 — FairBetter than 96% of packages Maintenance94 Actively maintained with recent releases Popularity30 Limited adoption so far Community20 Small or concentrated contributor base Maturity57 Maturing project, gaining track record Bus Factor1 Top contributor holds 79.8% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
