# 1.8.15

### Security fixes

* Fixed leak of the writable pad ID when exporting from the pad's read-only ID.
  This only matters if you treat the writeable pad IDs as secret (e.g., you are
  not using [ep_padlist2](https://www.npmjs.com/package/ep_padlist2)) and you
  share the pad's read-only ID with untrusted users. Instead of treating
  writeable pad IDs as secret, you are encouraged to take advantage of
  Etherpad's authentication and authorization mechanisms (e.g., use
  [ep_openid_connect](https://www.npmjs.com/package/ep_openid_connect) with
  [ep_readonly_guest](https://www.npmjs.com/package/ep_readonly_guest), or write
  your own
  [authentication](https://etherpad.org/doc/v1.8.14/#index_authenticate) and
  [authorization](https://etherpad.org/doc/v1.8.14/#index_authorize) plugins).

### Compatibility changes

* The `logconfig` setting is deprecated.
* For plugin authors:
  * Etherpad now uses [jsdom](https://github.com/jsdom/jsdom) instead of
    [cheerio](https://cheerio.js.org/) for processing HTML imports. There are
    two consequences of this change:
    * `require('ep_etherpad-lite/node_modules/cheerio')` no longer works. To
      fix, your plugin should directly depend on `cheerio` and do
      `require('cheerio')`.
    * The `node` context argument passed to the `collectContentImage` hook is
      now an
      [`HTMLImageElement`](https://developer.mozilla.org/en-US/docs/Web/API/HTMLImageElement)
      object rather than a Cheerio Node-like object, so the API is slightly
      different. See
      [citizenos/ep_image_upload#49](https://github.com/citizenos/ep_image_upload/pull/49)
      for an example fix.
  * The `clientReady` server-side hook is deprecated; use the new `userJoin`
    hook instead.
  * The `init_<pluginName>` server-side hooks are now run every time Etherpad
    starts up, not just the first time after the named plugin is installed.
  * The `userLeave` server-side hook's context properties have changed:
    * `auth`: Deprecated.
    * `author`: Deprecated; use the new `authorId` property instead.
    * `readonly`: Deprecated; use the new `readOnly` property instead.
    * `rev`: Deprecated.
  * Changes to the `src/static/js/Changeset.js` library:
    * `opIterator()`: The unused start index parameter has been removed, as has
      the unused `lastIndex()` method on the returned object.
    * `smartOpAssembler()`: The returned object's `appendOpWithText()` method is
      deprecated without a replacement available to plugins (if you need one,
      let us know and we can make the private `opsFromText()` function public).
    * Several functions that should have never been public are no longer
      exported: `applyZip()`, `assert()`, `clearOp()`, `cloneOp()`, `copyOp()`,
      `error()`, `followAttributes()`, `opString()`, `stringOp()`,
      `textLinesMutator()`, `toBaseTen()`, `toSplices()`.

### Notable enhancements

* Simplified pad reload after importing an `.etherpad` file.
* For plugin authors:
  * `clientVars` was added to the context for the `postAceInit` client-side
    hook. Plugins should use this instead of the `clientVars` global variable.
  * New `userJoin` server-side hook.
  * The `userLeave` server-side hook has a new `socket` context property.
  * The `helper.aNewPad()` function (accessible to client-side tests) now
    accepts hook functions to inject when opening a pad. This can be used to
    test any new client-side hooks your plugin provides.
  * Chat improvements:
    * The `chatNewMessage` client-side hook context has new properties:
      * `message`: Provides access to the raw message object so that plugins can
        see the original unprocessed message text and any added metadata.
      * `rendered`: Allows plugins to completely override how the message is
        rendered in the UI.
    * New `chatSendMessage` client-side hook that enables plugins to process the
      text before sending it to the server or augment the message object with
      custom metadata.
    * New `chatNewMessage` server-side hook to process new chat messages before
      they are saved to the database and relayed to users.

# 1.8.14

### Security fixes

* Fixed a persistent XSS vulnerability in the Chat component. In case you can't
  update to 1.8.14 directly, we strongly recommend to cherry-pick
  a7968115581e20ef47a533e030f59f830486bdfa. Thanks to sonarsource for the
  professional disclosure.

### Compatibility changes

* Node.js v12.13.0 or later is now required.
* The `favicon` setting is now interpreted as a pathname to a favicon file, not
  a URL. Please see the documentation comment in `settings.json.template`.
* The undocumented `faviconPad` and `faviconTimeslider` settings have been
  removed.
* MySQL/MariaDB now uses connection pooling, which means you will see up to 10
  connections to the MySQL/MariaDB server (by default) instead of 1. This might
  cause Etherpad to crash with a "ER_CON_COUNT_ERROR: Too many connections"
  error if your server is configured with a low connection limit.
* Changes to environment variable substitution in `settings.json` (see the
  documentation comments in `settings.json.template` for details):
  * An environment variable set to the string "null" now becomes `null` instead
    of the string "null". Similarly, if the environment variable is unset and
    the default value is "null" (e.g., `"${UNSET_VAR:null}"`), the value now
    becomes `null` instead of the string "null". It is no longer possible to
    produce the string "null" via environment variable substitution.
  * An environment variable set to the string "undefined" now causes the setting
    to be removed instead of set to the string "undefined". Similarly, if the
    environment variable is unset and the default value is "undefined" (e.g.,
    `"${UNSET_VAR:undefined}"`), the setting is now removed instead of set to
    the string "undefined". It is no longer possible to produce the string
    "undefined" via environment variable substitution.
  * Support for unset variables without a default value is now deprecated.
    Please change all instances of `"${FOO}"` in your `settings.json` to
    `${FOO:null}` to keep the current behavior.
  * The `DB_*` variable substitutions in `settings.json.docker` that previously
    defaulted to `null` now default to "undefined".
* Calling `next` without argument when using `Changeset.opIterator` does always
  return a new Op. See b9753dcc7156d8471a5aa5b6c9b85af47f630aa8 for details.

### Notable enhancements and fixes

* MySQL/MariaDB now uses connection pooling, which should improve stability and
  reduce latency.
* Bulk database writes are now retried individually on write failure.
* Minify: Avoid crash due to unhandled Promise rejection if stat fails.
* padIds are now included in /socket.io query string, e.g.
  `https://video.etherpad.com/socket.io/?padId=AWESOME&EIO=3&transport=websocket&t=...&sid=...`.
  This is useful for directing pads to separate socket.io nodes.
* <script> elements added via aceInitInnerdocbodyHead hook are now executed.
* Fix read only pad access with authentication.
* Await more db writes.
* Disabled wtfnode dump by default.
* Send `USER_NEWINFO` messages on reconnect.
* Fixed loading in a hidden iframe.
* Fixed a race condition with composition. (Thanks @ingoncalves for an exceptionally
  detailed analysis and @rhansen for the fix.)

### Security patches

* Fixed a regression in v1.8.11 which caused some pad names to cause Etherpad to restart.

### Notable fixes

* Fixed a bug in the `dirty` database driver that sometimes caused Node.js to
  crash during shutdown and lose buffered database writes.
* Fixed a regression in v1.8.8 that caused "Uncaught TypeError: Cannot read
  property '0' of undefined" with some plugins (#4885)
* Less warnings in server console for supported element types on import.
* Support Azure and other network share installations by using a 
  more truthful relative path.

### Notable enhancements

* Dependency updates.

# 1.8.8

### Security patches

* EJS has been updated to 3.1.6 to mitigate an Arbitrary Code Injection

### Compatibility changes

* Node.js 10.17.0 or newer is now required.
* The `bin/` and `tests/` directories were moved under `src/`. Symlinks were
  added at the old locations to hopefully avoid breaking user scripts and other
  tools.
* Dependencies are now installed with the `--no-optional` flag to speed
  installation. Optional dependencies such as `sqlite3` must now be manually
  installed (e.g., `(cd src && npm i sqlite3)`).
* Socket.IO messages are now limited to 10K bytes to make denial of service
  attacks more difficult. This may cause issues when pasting large amounts of
  text or with plugins that send large messages (e.g., `ep_image_upload`). You
  can change the limit via `settings.json`; see `socketIo.maxHttpBufferSize`.
* The top-level `package.json` file, added in v1.8.7, has been removed due to
  problematic npm behavior. Whenever you install a plugin you will see the
  following benign warnings that can be safely ignored:

  ```
  npm WARN saveError ENOENT: no such file or directory, open '.../package.json'
  npm WARN enoent ENOENT: no such file or directory, open '.../package.json'
  npm WARN develop No description
  npm WARN develop No repository field.
  npm WARN develop No README data
  npm WARN develop No license field.
  ```

### Notable enhancements

* You can now generate a link to a specific line number in a pad. Appending
  `#L10` to a pad URL will cause your browser to scroll down to line 10.
* Database performance is significantly improved.
* Admin UI now has test coverage in CI. (The tests are not enabled by default;
  see `settings.json`.)
* New stats/metrics: `activePads`, `httpStartTime`, `lastDisconnected`,
  `memoryUsageHeap`.
* Improved import UX.
* Browser caching improvements.
* Users can now pick absolute white (`#fff`) as their color.
* The `settings.json` template used for Docker images has new variables for
  controlling rate limiting.
* Admin UI now has test coverage in CI. (The tests are not enabled by default
  because the admin password is required; see `settings.json`.)
* For plugin authors:
  * New `callAllSerial()` function that invokes hook functions like `callAll()`
    except it supports asynchronous hook functions.
  * `callFirst()` and `aCallFirst()` now support the same wide range of hook
    function behaviors that `callAll()`, `aCallAll()`, and `callAllSerial()`
    support. Also, they now warn when a hook function misbehaves.
  * The following server-side hooks now support asynchronous hook functions:
    `expressConfigure`, `expressCreateServer`, `padCopy`, `padRemove`
  * Backend tests for plugins can now use the
    [`ep_etherpad-lite/tests/backend/common`](src/tests/backend/common.js)
    module to start the server and simplify API access.
  * The `checkPlugins.js` script now automatically adds GitHub CI test coverage
    badges for backend tests and npm publish.

### Notable fixes

* Enter key now stays in focus when inserted at bottom of viewport.
* Numbering for ordered list items now properly increments when exported to
  text.
* Suppressed benign socket.io connection errors
* Interface no longer loses color variants on disconnect/reconnect event.
* General code quality is further significantly improved.
* Restarting Etherpad via `/admin` actions is more robust.
* Improved reliability of server shutdown and restart.
* No longer error if no buttons are visible.
* For plugin authors:
  * Fixed `collectContentLineText` return value handling.

# 1.8.7
### Compatibility-breaking changes
* **IMPORTANT:** It is no longer possible to protect a group pad with a
  password. All API calls to `setPassword` or `isPasswordProtected` will fail.
  Existing group pads that were previously password protected will no longer be
  password protected. If you need fine-grained access control, you can restrict
  API session creation in your frontend service, or you can use plugins.
* All workarounds for Microsoft Internet Explorer have been removed. IE might
  still work, but it is untested.
* Plugin hook functions are now subject to new sanity checks. Buggy hook
  functions will cause an error message to be logged
* Authorization failures now return 403 by default instead of 401
* The `authorize` hook is now only called after successful authentication. Use
  the new `preAuthorize` hook if you need to bypass authentication
* The `authFailure` hook is deprecated; use the new `authnFailure` and
  `authzFailure` hooks instead
* The `indexCustomInlineScripts` hook was removed
* The `client` context property for the `handleMessage` and
  `handleMessageSecurity` hooks has been renamed to `socket` (the old name is
  still usable but deprecated)
* The `aceAttribClasses` hook functions are now called synchronously
* The format of `ENTER`, `CREATE`, and `LEAVE` log messages has changed
* Strings passed to `$.gritter.add()` are now expected to be plain text, not
  HTML. Use jQuery or DOM objects if you need formatting

### Notable new features
* Users can now import without creating and editing the pad first
* Added a new `readOnly` user setting that makes it possible to create users in
  `settings.json` that can read pads but not create or modify them
* Added a new `canCreate` user setting that makes it possible to create users in
  `settings.json` that can modify pads but not create them
* The `authorize` hook now accepts `readOnly` to grant read-only access to a pad
* The `authorize` hook now accepts `modify` to grant modify-only (creation
  prohibited) access to a pad
* All authentication successes and failures are now logged
* Added a new `cookie.sameSite` setting that makes it possible to enable
  authentication when Etherpad is embedded in an iframe from another site
* New `exportHTMLAdditionalContent` hook to include additional HTML content
* New `exportEtherpadAdditionalContent` hook to include additional database
  content in `.etherpad` exports
* New `expressCloseServer` hook to close Express when required
* The `padUpdate` hook context now includes `revs` and `changeset`
* `checkPlugin.js` has various improvements to help plugin developers
* The HTTP request object (and therefore the express-session state) is now
  accessible from within most `eejsBlock_*` hooks
* Users without a `password` or `hash` property in `settings.json` are no longer
  ignored, so they can now be used by authentication plugins
* New permission denied modal and block ``permissionDenied``
* Plugins are now updated to the latest version instead of minor or patches

* Fixed export of HTML attributes within a line
* Fixed occasional "Cannot read property 'offsetTop' of undefined" error in
  timeslider when "follow pad contents" is checked

  on X11 systems)
* Removal of Microsoft Internet Explorer specific code
* Import better handles line breaks and white space
* Fix issue with ``createDiffHTML`` incorrect call of ``getInternalRevisionAText``
* Allow additional characters in URLs
