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.

## 4.0

**target commit**: 9003f029f8fe087cde5bb081d51ab82340948874

**base librewolf version**: 95.x

**References**:
- [review webrtc](https://gitlab.com/librewolf-community/settings/-/issues/108).
- [stop disabling geo api](https://gitlab.com/librewolf-community/settings/-/issues/102).
- [deprecate RFP dark mode](https://gitlab.com/librewolf-community/browser/common/-/issues/56).
- `offlineApps` change in 3.1 did not respect exceptions, so revert it.
- uncomment prefs to enable CRL without OCSP fallback, although they will fully work only when [this issue is closed](https://gitlab.com/librewolf-community/browser/common/-/issues/57).
- we decided to force a larger new window size by default, to improve usability for RFP users while still keeping a rounded value. see [this comment](https://gitlab.com/librewolf-community/settings/-/issues/104#note_752186737).

#### Added preferences
```
defaultPref("privacy.window.maxInnerWidth", 1600);
defaultPref("privacy.window.maxInnerHeight", 900);
```

#### Removed preferences
```
defaultPref("media.peerconnection.enabled", false);
lockPref("privacy.override_rfp_for_color_scheme", false);
defaultPref("geo.enabled", false);
defaultPref("permissions.default.geo", 2);
defaultPref("privacy.clearOnShutdown.offlineApps", true);
defaultPref("privacy.cpd.offlineApps", true);
```

#### Changed preferences
```
defaultPref("security.remote_settings.crlite_filters.enabled", true);
defaultPref("security.pki.crlite_mode", 2);
```

## 3.2

**target commit**: 19e59813ed483de7ffc8a219da96eb18a942eb01

**base librewolf version**: 94.x

**References**:
- block the new firefox suggests feature in full.
- enforce a sane value for manual sanitizing.

**Notes**: the suggest prefs might be overkill, we should try to trim to the bare minimum in the next release.

#### Added preferences
```
lockPref("browser.urlbar.quicksuggest.enabled", false); // disable suggest and hide its ui
lockPref("browser.urlbar.suggest.quicksuggest.nonsponsored", false); // disable suggestions from firefox
lockPref("browser.urlbar.suggest.quicksuggest.sponsored", false); // disable sponsored suggestions
lockPref("browser.urlbar.quicksuggest.dataCollection.enabled", false); // default
defaultPref("privacy.sanitize.timeSpan", 0);
```
#### Changed preferences
```
lockPref("browser.urlbar.quicksuggest.scenario", "history"); // prevent opt-in, doesn't work alone
```

## 3.1

**target commit**: 6844d4ad1c9ad8bb3ffdc29e0a607c21c0559da4 and 67e6a00b719ecd52782a724cd09a9f08fa4577c0

**base librewolf version**: 94.x

**References**:
- the added prefs are all defense in depth.
- `drawInTitlebar` was causing errors for some users, the bug was reproduced. Linux users might experience a different toolbar behavior because of this change.
- the default value for scopes seems like a better choice than changing it.
- `offlineApps` can be safely cleared without using logins, in fact it was most likely cleared by other sanitazion techniques regardless.

**Notes**: please notify users about the new website, thanks to @maltejur for helping with the migration.

#### Added preferences
```
defaultPref("webchannel.allowObject.urlWhitelist", ""); // remove webchannel whitelist
lockPref("toolkit.telemetry.coverage.opt-out", true); // hidden
defaultPref("privacy.cpd.offlineApps", true); // for consistency with clearOnShutdown prefs
```

#### Removed preferences
```
defaultPref("extensions.autoDisableScopes", 11); // bring back to default
defaultPref("browser.tabs.drawInTitlebar", true); // bring back to default
```

#### Changed preferences
```
defaultPref("privacy.clearOnShutdown.offlineApps", true); // can be cleared
defaultPref("app.support.baseURL", "https://librewolf.net/docs/faq/#");
defaultPref("browser.search.searchEnginesURL", "https://librewolf.net/docs/faq/#how-do-i-add-a-search-engine");
defaultPref("browser.geolocation.warning.infoURL", "https://librewolf.net/docs/faq/#how-do-i-enable-location-aware-browsing");
defaultPref("app.feedback.baseURL", "https://librewolf.net/#questions");
```

## 3.0

**target commit**: f0a2d5d70657cc87348282d6faaf72edff8bf304 and 4e0895a299ec99066f119d8ce1a2923fc91aa465

**base librewolf version**: 94.x

**References**:
- as reported in #95 and discussed [here](https://gitlab.com/librewolf-community/browser/linux/-/issues/246) we are re-enabling TP by default, setting it to strict.
- the sponsored shortcuts in about:preferences#home were already locked, now they are properly hidden.
- enable fission as it is being [rolled out to stable](https://bugzilla.mozilla.org/show_bug.cgi?id=1732206).

**Notes**: all the removed preferences were either related to disabling TP, or unecessary when using strict mode. as a result of this trimming the tracking protection section of the .cfg file doesn't need to exist anymore.

#### Added preferences
```
defaultPref("browser.topsites.useRemoteSetting", false); // hide sponsored shortcuts button from about:preferences#home
defaultPref("privacy.resistFingerprinting.letterboxing", false); // expose hidden letterboxing pref, but do not enable by default
defaultPref("fission.autostart", true); // enable fission by default
```

#### Removed preferences
```
lockPref("privacy.trackingprotection.enabled", false);
lockPref("privacy.trackingprotection.pbmode.enabled", false);
lockPref("privacy.trackingprotection.annotate_channels", false);
defaultPref("browser.safebrowsing.provider.mozilla.updateURL", "");
defaultPref("browser.safebrowsing.provider.mozilla.gethashURL", "");
defaultPref("privacy.trackingprotection.cryptomining.enabled", false);
defaultPref("privacy.trackingprotection.fingerprinting.enabled", false);
defaultPref("browser.contentblocking.cryptomining.preferences.ui.enabled", false);
defaultPref("browser.contentblocking.fingerprinting.preferences.ui.enabled", false);
```

#### Changed preferences
```
pref("browser.contentblocking.category", "strict");
```

## 2.0

**target commit**: from 6451faa167568313e5ed065fcb3ee2bb76132063 to b17a1ed657e22ac61b4399699223d36724b842e7

**base librewolf version**: 92.x

**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**: 192f51abe21e9aeb9b01d396079e9b8533cab7bb

**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

**base librewolf version**: 89.x

This is the initial release from which we start tagging and versioning settings. For previous changes see 
[here](https://gitlab.com/librewolf-community/settings/-/blob/master/docs/changelog-legacy.md).
