WP YouTube Lyte

• bugfix for regression in parsing improvements which in some cases saw links to youtube being shown as LYTE as well.
• improvement to lyteCache request sanitation (hat tip to Siina Chavoshlu for reporting & testing the fix)
• other minor changes, see GitHub commits

• misc. parsing improvements, resulting in YT shorts working as well.

• improvements to the alternative lazyload feature (kudos to Stirius & believableUN and softromano for helping/ testing!)
• lyteCache: if maxresdefault.jpg does not exist, try hqdefault.jpg instead (contribution of R33D3M33R, thanks!)
• some extra filters

• small improvements to the integration with the YouTube API, thanks to enchamun and mountbatt for their assistance!

• misc improvements as suggested by WordPress Plugins team
• filter added to set description as proposed & contributed by Patrick Robertson
• filter added to disable fallback to youtube thumbnail as proposed & contributed by Benjamin Pick
• logic added to switch to different type of lazyload behavior proposed & contributed by @softmanro

• added extra sanitization, thanks m0ze!
• optionally disable thumbnail fallback to youtube servers (contributed by Benjamin Pick)
• general code cleanup (spaces, double -> single quotes around strings, ...)
• misc. smaller fixes/ improvements, see Github commits for details.

• To avoid YouTube cutting API access because no requests were made for 3 months, LYTE now by default caches the YouTube data for 2 months, after which it is refreshed. Previously cached data only refreshed if the cache got cleared manually.

• fix WordPress core blocks "recent posts block" breaking when summary or full article were shown.
• remove old language-files (translations are now entirely handled via https://translate.wordpress.org/projects/wp-plugins/wp-youtube-lyte/
• add logic to lyteCache.php to prevent (ab)use like e.g. hotlinking (needs to be enabled with lyte_filter_local_thumb_doublecheck filter) or lyteCache caching even if local thumbnail caching is off.
• some smaller fixes.

• fix regression causing HTML comments to break

• fix for dash becoming double dash
• move lyteThumbs.php to lyteCache.php because security solutions generally are traumatized by all things thumbs

• some other smaller changes, see https://github.com/futtta/wp-youtube-lyte/commits/main

• fix playlist that got broken due to the priority change (from 4 to 10)
• add is_amp (and is_feed) checks to the new lyte_prepare function (which runs at priority 4)

• fix regression for YouTube embed WordPress block (https://wordpress.org/support/topic/errors-caused-by-upgrading-to-version-1-7-9/) due to changed priority in 1.7.9.

• improved AMP checking (LYTE should never be active on AMP pages)
• improvements to gutenberg block parsing
• switch filter priority to 10 instead of 4 to allow "catching" more rendered YouTube videos
• fix jsapi breakeage
• misc. smaller changes/ fixes

• improvement: if extracted from Gutenburg YouTube embed blocks keep the figure-tag with all relevant CSS classes and keep the caption (if set).

• improvement: make sure locally cached thumbnails are served with good HTTP response headers (allowing HTTP 304 responses and allowing images to be cached in browser).
• improvemnet: bigger widget sizes for use in pagebuilders.

• switched YouTube to youtube-nocookie.com.
• added span around description to ensure it can be styled separately.

• new: you can add a text underneath each video (e.g. for privacy disclaimer purposes, think GDPR) by adding it on the settings-page
• fix: thumbnails from LYTE without API key can now also be cached locally

• Finally fixed a nasty bug that caused API key validation to fail on PHP 7.1 and higher. A big thank you to @emilyatal, @mkalina, @nicolaottomano, @aminech, @partounian, @nicksws who all provided valuable input in the WordPress LYTE support forum and tested multiple debug-versions to help fix this.

• new: option to have thumbnail hosted locally to improve performance and privacy (I am not a lawyer, but this could make embedded YouTube GDPR compliant as not requests are sent to YouTube unless/ until the video is played).

• make widgets not break HTTPS (thanks R33D3M33R)

• new: support for Gutenberg blocks with embedded YouTube (tested with Gutenberg plugin version 2.3.0)

• improvement: enter "none" in API key not to be bothered by the missing key notice any more (as requested by TheGiantRedFox1986)
• improvement: if no API key (or "none" for key) is provided, don't try to contact YouTube any more, instead just setting a thumbnail (does not work for playlists).
• cleanup: removed code that catered to YouTube API v2.

• Fixed some PHP notices in widget.php

• update: javascript now initiates either after full page load or after 1 second (whatever comes first), thus avoiding video not showing due to other requests taking too long

• admin-page now contains links to most recent info (blogposts) on WP YouTube Lyte (and optionally WordPress and Web Technology in general) using the excellent jQuery-plugin zrssfeed

• There now is a WP-YouTube-Lyte widget which you can add to your sidebar (see under "Appearance"->"Widgets"), as requested by the fabulous fruityoaty
