    1415== Changelog ==
    1516
    16 = 2024-12-06 1.1.1 =
    17 * 1.2 was broken. Revert release.
     17= 2024-12-06 1.2.1 =
     18* Fix: Code mistake caused `integrity` attribute to be wrong, plugin files would get blocked.
     19
     20= 2024-12-04 1.2.0 =
     21* New: A info dialog was added that is only loaded when the admin bar is visible.
     22* New/Fix: Support for script modules.
     23* Improved: Shorten potentially too long transient names.
     24* Improved: Replaced `get_headers` with `wp_safe_remote_head`. WP coding standards and more efficient.
     25* Improved: Simplified and improved the code.
    1826
    1927= 2024-05-14 1.1.0 =
    … …  
    2331* Run only once per page-load.
    2432* Better function names and some useful comments.
    25 * Send this plugins url as user-agent to jsDelivr knows how its used. (They asked for this). This also means more privacy as the `wp_remote_get` referrer sends your site URL (I really do not like that)
     33* Send this plugins url as user-agent to jsDelivr knows how it's used. (They asked for this). This also means more privacy as the `wp_remote_get` referrer by default would send your site URL (I really do not like that)

    … …  
    3543
    3644== Description ==
    37 It replaces all WP Core assets with versions hosted on jsDelivr.
     45It replaces all assets with versions available on jsDelivr. No options, nothing to configure, just works.
    3846
    39 The following conditions need to be met that plugins assets will be served from jsDeliver:
     47The code needs to be openly hosted on NPM, Github or wordpress.org.
    4048
    41 1. The plugin needs to be hosted on wp.org. Commercial plugins and plugins from elsewhere will not work because jsDelivr mirrors the wp.org plugin dir and nothing else.
    42 1. The asset src URL most have `/plugins/plugin-slug/` in them and end with `.js` or `.css` (excluding cash busting `?ver=1.2.3`).
    43 1. It needs to have its current version published as a tag on the wp.org plugins SVN. Some plugins may only push to /trunk/ (like my own at the time of writing) or do not have their latest version published as tags.
     49This plugin adds a little a invisible button on the admin bar on the top right, left of "Howdy, Name". You can click that and see the assets loaded from jsDelivr.

    47 It took me a lot of time to come up with this plugin and I had many iterations over various different approaches how to do this until I came up with this working solution that also does not need much code. I know the official plugin was abandoned years ago and I looked at complicated bloated code and did not even feel like learning what its doing and never looked at it again and started from scratch. [Please donate here](https://nextgenthemes.com/donate/).

    16 = 2024-12-06 1.1.1 =
    17 * 1.2 was broken. Revert release.
     17= 2024-12-06 1.2.1 =
     18* Fix: Code mistake caused `integrity` attribute to be wrong, plugin files would get blocked.
     19
     20= 2024-12-04 1.2.0 =
     21* New: A info dialog was added that is only loaded when the admin bar is visible.
     22* New/Fix: Support for script modules.
     23* Improved: Shorten potentially too long transient names.
     24* Improved: Replaced `get_headers` with `wp_safe_remote_head`. WP coding standards and more efficient.
     25* Improved: Simplified and improved the code.
    1826
    1927= 2024-05-14 1.1.0 =
    … …  
    2331* Run only once per page-load.
    2432* Better function names and some useful comments.
    25 * Send this plugins url as user-agent to jsDelivr knows how its used. (They asked for this). This also means more privacy as the `wp_remote_get` referrer sends your site URL (I really do not like that)
     33* Send this plugins url as user-agent to jsDelivr knows how it's used. (They asked for this). This also means more privacy as the `wp_remote_get` referrer by default would send your site URL (I really do not like that)

    3644== Description ==
    37 It replaces all WP Core assets with versions hosted on jsDelivr.
     45It replaces all assets with versions available on jsDelivr. No options, nothing to configure, just works.
    3846
    39 The following conditions need to be met that plugins assets will be served from jsDeliver:
     47The code needs to be openly hosted on NPM, Github or wordpress.org.
    4048
    41 1. The plugin needs to be hosted on wp.org. Commercial plugins and plugins from elsewhere will not work because jsDelivr mirrors the wp.org plugin dir and nothing else.
    42 1. The asset src URL most have `/plugins/plugin-slug/` in them and end with `.js` or `.css` (excluding cash busting `?ver=1.2.3`).
    43 1. It needs to have its current version published as a tag on the wp.org plugins SVN. Some plugins may only push to /trunk/ (like my own at the time of writing) or do not have their latest version published as tags.
     49This plugin adds a little a invisible button on the admin bar on the top right, left of "Howdy, Name". You can click that and see the assets loaded from jsDelivr.

    47 It took me a lot of time to come up with this plugin and I had many iterations over various different approaches how to do this until I came up with this working solution that also does not need much code. I know the official plugin was abandoned years ago and I looked at complicated bloated code and did not even feel like learning what its doing and never looked at it again and started from scratch. [Please donate here](https://nextgenthemes.com/donate/).
