# Next release

#### Note for admins
Etherpad does no longer store it's dependencies in ./src/node_modules by default. Also, Etherpad now
stores installed plugins in a package.json file in the root directory and no longer requires quirks
like `--legacy-peer-deps` or `--no-save` when invoking npm during plugin installation.

When you're updating, it's best to use the `./src/bin/installDeps.sh` script. It will `npm link` the
src directory, using the package.json file in ./src. This will create the well-known symlink ep_etherpad-lite
in ./node_modules, that we've been using for years. However, this will also add a dependency in ./package.json.

`./src/bin/installDeps.sh` will fail, if you have no ./package.json or ./package-lock.json and your
./node_modules directory is not empty, as this is an indicator of installed plugins. You need to remove
./node_modules and install all your plugins in the next step.

`./src/bin/installDeps.sh` will remove any existing directories in `./src/node_modules`.

After running `./src/bin/installDeps.sh`, install your plugins with `npm i ep_plugin1 ep_plugin2...` or via
`/admin/plugins`.


#### Note for plugin authors
You can no longer depend on core's dependencies via `require('ep_etherpad-lite/node_modules/$dep')`.
Please run `src/bin/checkPlugins.sh` or manually change to `require('$dep')`. We don't recommend
that you rely on Etherpad to include specific dependencies in the future. So it's best if you add
the dependency in your package.json.
For convenience we have added symlinks in ./src/node_modules for the following dependencies:
async, cheerio, express, formidable, log4js and supertest.
Please note that those symlinks will be removed in a future version, so we strongly recommend that
you adapt your require statements.

# 1.9.3

### Compability changes

* express-rate-limit has been bumped to 7.0.0: This involves the breaking change that "max: 0"
in the importExportRateLimiting is set to always trigger. So set it to your desired value.
If you haven't changed that value in the settings.json you are all set. 

### Notable enhancements and fixes

* Bugfixes
  * Fix etherpad crashing with mongodb database

* Enhancements
  * Add surrealdb database support. You can find out more about this database [here](https://surrealdb.com).
  * Make sqlite faster: The sqlite library has been switched to better-sqlite3. This should lead to better performance.

# 1.9.2

### Notable enhancements and fixes

* Security
  * Enable session key rotation: This setting can be enabled in the settings.json. It changes the signing key for the cookie authentication in a fixed interval.

* Bugfixes
  * Fix appendRevision when creating a new pad via the API without a text. 


* Enhancements
  * Bump JQuery to version 3.7
  * Update elasticsearch connector to version 8

### Compatibility changes

* No compability changes as JQuery maintains excellent backwards compatibility. 

#### For plugin authors

* Please update to JQuery 3.7. There is an excellent deprecation guide over [here](https://api.jquery.com/category/deprecated/). Version 3.1 to 3.7 are relevant for the upgrade. 

# 1.9.1

### Notable enhancements and fixes

* Security
  * Limit requested revisions in timeslider and export to head revision. (affects v1.9.0)
  
* Bugfixes
  * revisions in `CHANGESET_REQ` (timeslider) and export (txt, html, custom)
    are now checked to be numbers.
  * bump sql for audit fix
* Enhancements
  * Add keybinding meta-backspace to delete to beginning of line
  * Fix automatic Windows build via GitHub Actions
  * Enable docs to be build cross platform thanks to asciidoctor

### Compatibility changes
* tests: drop windows 7 test coverage & use chrome latest for admin tests
* Require Node 16 for Etherpad and target Node 20 for testing

    
# 1.9.0

### Notable enhancements and fixes

* Windows build:
  * The bundled `node.exe` was upgraded from v12 to v16.
  * The bundled `node.exe` is now a 64-bit executable. If you need the 32-bit
    version you must download and install Node.js yourself.
* Improvements to login session management:
  * `express_sid` cookies and `sessionstorage:*` database records are no longer
    created unless `requireAuthentication` is `true` (or a plugin causes them to
    be created).
  * Login sessions now have a finite lifetime by default (10 days after
    leaving).
  * `sessionstorage:*` database records are automatically deleted when the login
    session expires (with some exceptions that will be fixed in the future).
  * Requests for static content (e.g., `/robots.txt`) and special pages (e.g.,
    the HTTP API, `/stats`) no longer create login session state.
  * The secret used to sign the `express_sid` cookie is now automatically
    regenerated every day (called *key rotation*) by default. If key rotation is
    enabled, the now-deprecated `SESSIONKEY.txt` file can be safely deleted
    after Etherpad starts up (its content is read and saved to the database and
    used to validate signatures from old cookies until they expire).
* The following settings from `settings.json` are now applied as expected (they
  were unintentionally ignored before):
  * `padOptions.lang`
  * `padOptions.showChat`
  * `padOptions.userColor`
  * `padOptions.userName`
* HTTP API:
  * Fixed the return value of `getText` when called with a specific revision.
  * Fixed a potential attribute pool corruption bug with
    `copyPadWithoutHistory`.
  * Mappings created by `createGroupIfNotExistsFor` are now removed from the
    database when the group is deleted.
  * Fixed race conditions in the `setText`, `appendText`, and `restoreRevision`
    functions.
  * Added an optional `authorId` parameter to `appendText`,
    `copyPadWithoutHistory`, `createGroupPad`, `createPad`, `restoreRevision`,
    `setHTML`, and `setText`, and bumped the latest API version to 1.3.0.
* Fixed a crash if the database is busy enough to cause a query timeout.
* New `/health` endpoint for getting information about Etherpad's health (see
  [draft-inadarei-api-health-check-06](https://www.ietf.org/archive/id/draft-inadarei-api-health-check-06.html)).
* Docker now uses the new `/health` endpoint for health checks, which avoids
  issues when authentication is enabled. It also avoids the unnecessary creation
  of database records for managing browser sessions.
* When copying a pad, the pad's records are copied in batches to avoid database
  timeouts with large pads.
* Exporting a large pad to `.etherpad` format should be faster thanks to bulk
  database record fetches.
* When importing an `.etherpad` file, records are now saved to the database in
  batches to avoid database timeouts with large pads.

#### For plugin authors

* New `expressPreSession` server-side hook.
* Pad server-side hook changes:
  * `padCheck`: New hook.
  * `padCopy`: New `srcPad` and `dstPad` context properties.
  * `padDefaultContent`: New hook.
  * `padRemove`: New `pad` context property.
* The `db` property on Pad objects is now public.
* New `getAuthorId` server-side hook.
* New APIs for processing attributes: `ep_etherpad-lite/static/js/attributes`
  (low-level API) and `ep_etherpad-lite/static/js/AttributeMap` (high-level
  API).
* The `import` server-side hook has a new `ImportError` context property.
* New `exportEtherpad` and `importEtherpad` server-side hooks.
* The `handleMessageSecurity` and `handleMessage` server-side hooks have a new
  `sessionInfo` context property that includes the user's author ID, the pad ID,
  and whether the user only has read-only access.
* The `handleMessageSecurity` server-side hook can now be used to grant write
  access for the current message only.
* The `init_<pluginName>` server-side hooks have a new `logger` context
  property that plugins can use to log messages.
* Prevent infinite loop when exiting the server
* Bump dependencies


### Compatibility changes

* Node.js v14.15.0 or later is now required.
* The default login session expiration (applicable if `requireAuthentication` is
  `true`) changed from never to 10 days after the user leaves.

#### For plugin authors

* The `client` context property for the `handleMessageSecurity` and
  `handleMessage` server-side hooks is deprecated; use the `socket` context
  property instead.
* Pad server-side hook changes:
  * `padCopy`:
    * The `originalPad` context property is deprecated; use `srcPad` instead.
    * The `destinationID` context property is deprecated; use `dstPad.id`
      instead.
  * `padCreate`: The `author` context property is deprecated; use the new
    `authorId` context property instead. Also, the hook now runs asynchronously.
  * `padLoad`: Now runs when a temporary Pad object is created during import.
    Also, it now runs asynchronously.
  * `padRemove`: The `padID` context property is deprecated; use `pad.id`
    instead.
  * `padUpdate`: The `author` context property is deprecated; use the new
    `authorId` context property instead. Also, the hook now runs asynchronously.
* Returning `true` from a `handleMessageSecurity` hook function is deprecated;
  return `'permitOnce'` instead.
* Changes to the `src/static/js/Changeset.js` library:
  * The following attribute processing functions are deprecated (use the new
    attribute APIs instead):
    * `attribsAttributeValue()`
    * `eachAttribNumber()`
    * `makeAttribsString()`
    * `opAttributeValue()`
  * `opIterator()`: Deprecated in favor of the new `deserializeOps()` generator
    function.
  * `appendATextToAssembler()`: Deprecated in favor of the new `opsFromAText()`
    generator function.
  * `newOp()`: Deprecated in favor of the new `Op` class.
* The `AuthorManager.getAuthor4Token()` function is deprecated; use the new
  `AuthorManager.getAuthorId()` function instead.
* The exported database records covered by the `exportEtherpadAdditionalContent`
  server-side hook now include keys like `${customPrefix}:${padId}:*`, not just
  `${customPrefix}:${padId}`.
* Plugin locales should overwrite core's locales Stale
* Plugin locales overwrite core locales

# 1.8.18

Released: 2022-05-05

### Notable enhancements and fixes

  * Upgraded ueberDB to fix a regression with CouchDB.

# 1.8.17

Released: 2022-02-23

### Security fixes

* Fixed a vunlerability in the `CHANGESET_REQ` message handler that allowed a
  user with any access to read any pad if the pad ID is known.

### Notable enhancements and fixes

* Fixed a bug that caused all pad edit messages received at the server to go
  through a single queue. Now there is a separate queue per pad as intended,
  which should reduce message processing latency when many pads are active at
  the same time.

# 1.8.16

### Security fixes

If you cannot upgrade to v1.8.16 for some reason, you are encouraged to try
cherry-picking the fixes to the version you are running:

```shell
git cherry-pick b7065eb9a0ec..77bcb507b30e
```

* Maliciously crafted `.etherpad` files can no longer overwrite arbitrary
  non-pad database records when imported.
* Imported `.etherpad` files are now subject to numerous consistency checks
  before any records are written to the database. This should help avoid
  denial-of-service attacks via imports of malformed `.etherpad` files.

### Notable enhancements and fixes

* Fixed several `.etherpad` import bugs.
* Improved support for large `.etherpad` imports.

# 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).
* Updated dependencies.

### 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 `collectContentImage` hook's `node` context property 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 and fixes

* Accessibility fix for JAWS screen readers.
* Fixed "clear authorship" error (see issue #5128).
* Etherpad now considers square brackets to be valid URL characters.
* The server no longer crashes if an exception is thrown while processing a
  message from a client.
* The `useMonospaceFontGlobal` setting now works (thanks @Lastpixl!).
* Chat improvements:
  * The message input field is now a text area, allowing multi-line messages
    (use shift-enter to insert a newline).
  * Whitespace in chat messages is now preserved.
* Docker improvements:
  * New `HEALTHCHECK` instruction (thanks @Gared!).
  * New `settings.json` variables: `DB_COLLECTION`, `DB_URL`,
    `SOCKETIO_MAX_HTTP_BUFFER_SIZE`, `DUMP_ON_UNCLEAN_EXIT` (thanks
    @JustAnotherArchivist!).
  * `.ep_initialized` files are no longer created.
* Worked around a [Firefox Content Security Policy
  bug](https://bugzilla.mozilla.org/show_bug.cgi?id=1721296) that caused CSP
  failures when `'self'` was in the CSP header. See issue #4975 for details.
* UeberDB upgraded from v1.4.10 to v1.4.18. For details, see the [ueberDB
  changelog](https://github.com/ether/ueberDB/blob/master/CHANGELOG.md).
  Highlights:
  * The `postgrespool` driver was renamed to `postgres`, replacing the old
    driver of that name. If you used the old `postgres` driver, you may see an
    increase in the number of database connections.
  * For `postgres`, you can now set the `dbSettings` value in `settings.json` to
    a connection string (e.g., `"postgres://user:password@host/dbname"`) instead
    of an object.
  * For `mongodb`, the `dbName` setting was renamed to `database` (but `dbName`
    still works for backwards compatibility) and is now optional (if unset, the
    database name in `url` is used).
* `/admin/settings` now honors the `--settings` command-line argument.
* Fixed "Author *X* tried to submit changes as author *Y*" detection.
* Error message display improvements.
* 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.
* Readability improvements to browser-side error stack traces.
* Added support for socket.io message acknowledgments.

# 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.)

# 1.8.13

### Notable fixes

* Fixed a bug in the safeRun.sh script (#4935)
* Add more endpoints that do not need authentication/authorization (#4921)
* Fixed issue with non-opening device keyboard on smartphones (#4929)
* Add version string to iframe_editor.css to prevent stale cache entry (#4964)

### Notable enhancements

* Refactor pad loading (no document.write anymore) (#4960)
* Improve import/export functionality, logging and tests (#4957)
* Refactor CSS manager creation (#4963)
* Better metrics
* Add test for client height (#4965)

### Dependencies

* ueberDB2 1.3.2 -> 1.4.4
* express-rate-limit 5.2.5 -> 5.2.6
* etherpad-require-kernel 1.0.9 -> 1.0.11

# 1.8.12

Special mention: Thanks to Sauce Labs for additional testing tunnels to help us
grow! :)

### 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
* Various Docker deployment improvements
* Various new translations
* Improvement of rendering of plugin hook list and error message handling

# 1.8.11

### Notable fixes

* Fix server crash issue within PadMessageHandler due to SocketIO handling
* Fix editor issue with drop downs not being visible
* Ensure correct version is passed when loading front end resources
* Ensure underscore and jquery are available in original location for plugin comptability

### Notable enhancements

* Improved page load speeds

# 1.8.10

### Security Patches

* Resolve potential ReDoS vulnerability in your project - GHSL-2020-359

### Compatibility changes

* JSONP API has been removed in favor of using the mature OpenAPI implementation.
* Node 14 is now required for Docker Deployments

### Notable fixes

* Various performance and stability fixes

### Notable enhancements

* Improved line number alignment and user experience around line anchors
* Notification to admin console if a plugin is missing during user file import
* Beautiful loading and reconnecting animation
* Additional code quality improvements
* Dependency updates

# 1.8.9

### Notable fixes

* Fixed HTTP 400 error when importing via the UI.
* Fixed "Error: spawn npm ENOENT" crash on startup in Windows.

### Notable enhancements

* Removed some unnecessary arrow key handling logic.
* 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
