General

Add a title option to GM_registerMenuCommand

Add script version number when saving a script

Content-security-policy (CSP) directives are not relaxed by default anymore
Notes:

In Chrome script injection should work as usual but some userscripts might depent on a relaxed CSP
In Firefox, if the page CSP blocks injection, userscripts are now injected into a JavaScript-mode @sandbox, which might require cloneInto and friends for unsafeWindow property modification
The old behavior can be restored by setting 'Modify existing content security policy (CSP) headers' to 'Yes'
This change helps to better comply with the Mozilla add-on development policies

Locally modified scripts are still not updated, but now can be reverted by a manual update and confirmation

Experimental @sandbox support with possible values 'raw', 'JavaScript' and 'DOM'

'raw' access means that a script for compatibility reasons always needs to run in page context. At the moment this mode is the default if @sandbox is omitted.
'JavaScript' access mode means that this script needs unsafeWindow access. At Firefox a special context is created which should also bypass all remaining CSP issues. Execution in page context is used as fallback at other browsers.
'DOM' access mode means that the script only needs DOM and no direct unsafeWindow access. If enabled these scripts are executed inside the extension context or at any other enabled context otherwise.

Add an option to configure available sandbox modes
Warning: Any option that enables 'DOM' mode is potentially unsecure. Userscripts that run in extension context have almost full extension permissions and can even modify and install new userscripts.

Remove document.addEventListener('DOMContentLoaded', ...) delayed event dispatching for document-start scripts executed later than the event

General

Sandbox improvements

Improved compatibility for userstyles installed as userscript

Add an option to control whether to bind GM API functions to the userscript's execution context and sandbox window (and do it by default only if necessary)
Details: Enabling this makes it very easy for a userscript to accidentally leak its granted powers to the page

Treat @include a little bit more like @match if :// is present and add an option to control @include's behavior
Details: Many script developers expect @include *://tmnk.net/* to match pages at tmnk.net only, but it also matches https://example.com/?http://tmnk.net/.
To improve this, @includes that contain a :// are now interpreted a little bit different. Every * before :// now only matches the URL scheme. Also, if :// is directly followed by a * or a / somewhere, then the first * or all until / are applied to the hostname only.
