Changes Version 2.7.1

Released on November 10, 2022 with 22 commits

This is a maintenance release to bridge the time until Unpoly 3 is fully documented. This release includes the following changes:

• When a fragment is revealed, fixed elements obstructing the viewport are now ignored while the fixed element is hidden.
• Listeners to up:request:load may now access the unopened XMLHttpRequest instance through event.xhr. This lets you track upload progress through event.xhr.upload. (Thanks @iaddict!)
• Listeners to up:layer:accept may change the layer's acceptance value by setting or mutating event.value.
• Listeners to up:layer:dismiss may change the layer's dismissal value by setting or mutating event.value.
• Fix a bug where right-aligned popups would have right-aligned text
• Fix a bug where clicking links twice will not update location when the browser history API is used in between (#388)

This is the last release with support for Internet Explorer 11. Future releases will support Chrome, Firefox, Edge and the last two majors of Safari.
