foxgirl-settings/docs/Changelog.md

This changelog will be used from now on to document changes in a precise manner, with a list of changes for each setting version.
Setting versions are documented using the pref `librewolf.cfg.version`, available in about:config.

## 2.0

**References**:
- [web content can no longer access the battery api](https://bugzilla.mozilla.org/show_bug.cgi?id=1313580).
- http alternative services are [isolated by network partitioning and FPI](https://github.com/arkenfox/user.js/blob/269cf965bd51022ca69823f8f66a8e402280d856/user.js#L1350) and they are unchanged even in tor browser. from a security standpoint, the alternate service will need to provide the certificate of the origin in order to be considered trusthworthy.
- let the user decide what to manually clear, including the timespan.
- drm prefs have been trimmed as a quality of life improvement. the end result is the same, with less hassle for users who want to access drm-protected content.
- DNT header has been proved to not work and it is used to fingerprint.
- VR access is behind a prompt and, despite being unlikely, it could be fingerprinted. with all this on the table it's just not worth and overkill.
- vibrator API is so nieche that even tor does not change it. best to trim where possible.
- `extensions.getAddons.link.url"` is showed only when no extension is installed and it's not a bad suggestion to get addons from addons.mozilla.org so we can remove it.
- `browser.safebrowsing.downloads.remote.*` are all controlled by the prefs already in the .cfg, which is the same approach taken by tor browser.
- graphite [is no longer as concerning](https://cve.mitre.org/cgi-bin/cvekey.cgi?keyword=firefox+graphite) and blocking it is likely fingerprintable.
- the pdf prefs and the bookmark backup are not really relevant to librewolf.
- as reported [here](https://bugzilla.mozilla.org/show_bug.cgi?id=1606624) the shared memory pref is no longer needed, so we can switch it back to default.
- new tab page section now includes a new design and no longer an empty page. all the unnecessary preferences have been removed and users can also customize as the most essential ones have been unlocked.
- UI bug in tracking protection section is fixed.
- a bunch of dead links are fixed.
- for screensharing see [testing provided at this link](https://github.com/arkenfox/user.js/issues/1245)
- disable new firefox suggests feature

## 1.6

**target commit**:

**base librewolf version**: 91.x

**References**:
- [reasoning on webgl2](https://github.com/arkenfox/user.js/commit/41c3c0ec26ef4392169fa1d04fd5783ac03bfc8e) from arkenfox's maintainer, basically disabling webgl is enough for those who don't need it. users who want it have one less pref to change.

#### Removed preferences
```
defaultPref("dom.targetBlankNoOpener.enabled", true); // default since v79.0
defaultPref("webgl.enable-webgl2", false);
lockPref("browser.newtabpage.activity-stream.feeds.section.highlights", false); // default
