    Update changelog

  • Raymond Hill (09 Jul 26)

    Add `prevent-clipboard-write` scriptlet Requires a trusted source. * @scriptlet prevent-clipboard-write * * @description * Prevent the clipboard from being overwritten. * * @param needle * A pattern or regex to match against the text for the prevention to occur. * * @param domAlert * Optional. A vararg to be used to alert the user in case a clipboard write * operation was prevented. The parameter is composed of two parts separated by * `|`: the first part is a CSS selector used to target a DOM element which * content will be replaced with the text found in the second part. * * @example * ##+js(prevent-clipboard-write, /^bash <<</, domAlert, body|Clickfix attempt defused) As discussed with filter list maintainers.
