 ## 0.1.1 [2017-06-03]
 ### Added
 - `serverlog.client` and `serverlog.server` options added to `config.json` to enable logging of client commands to server log (only client portion implemented at this time)
 - morgan express middleware for logging
 ### Changed
 - Updated socket.io to 1.7.4
 - continued refactoring, breaking up `index.js`
 - revised error handling methods
 - revised session termination methods
 ### Fixed
 ### Removed
 - color console decorations from `util/index.js`
 - SanatizeHeaders function from `util/index.js`
 ## 0.1.0 [2017-05-27]
 ### Added
 - This ChangeLog.md file
 - Support for UTF-8 characters (thanks @bara666)
 - Snyk, Bithound, Travis CI
 - Cross platform improvements (path mappings)
 - Session fixup between Express and Socket.io
 - Session secret settings in `config.json`
 - env variable `DEBUG=ssh2` will put the `ssh2` module into debug mode
 - env variable `DEBUG=WebSSH2` will output additional debug messages for functions
 and events in the application (not including the ssh2 module debug)
 - using Grunt to pull js and css source files from other modules `npm run build` to rebuild these if changed or updated.
 - `useminified` option in `config.json` to enable using minified client side javascript (true) defaults to false (non-minified)
 - sshterm= query option to specify TERM environment variable for host, valid strings are alpha-numeric with a hypen (validated). Otherwise the default ssh.term variable from `config.json` will be used.
 - validation for host (v4,v6,fqdn,hostname), port (integer 2-65535), and header (sanitized) from URL input
 ### Changed
 - error handling in public/client.js
 - moved socket.io operations to their own file /socket/index.js, more changes like this to come (./socket/index.js)
 - all session based variables are now under the req.session.ssh property or socket.request.ssh (./index.js)
 - moved SSH algorithms to `config.json` and defined as a session variable (..session.ssh.algorithms)
 -- prep for future feature to define algorithms in header or some other method to enable separate ciphers per host
 - minified and combined all js files to a single js in `./public/webssh2.min.js` also included a sourcemap `./public/webssh2.min.js` which maps to `./public/webssh2.js` for easier troubleshooting.
 - combined all css files to a single css in `./public/webssh2.css`
 - minified all css files to a single css in `./public/webssh2.min.css`
 - copied all unmodified source css and js to /public/src/css and /public/src/js respectively (for troubleshooting/etc)
 - sourcemaps of all minified code (in /public/src and /public/src/js)
 - renamed `client.htm` to `client-full.htm`
 - created `client-min.htm` to serve minified javascript
 - if header.text is null in `config.json` and header is not defined as a get parameter the Header will not be displayed. Both of these must be null / undefined and not specified as get parameters.
 ### Fixed
 - Multiple errors may overwrite status bar which would cause confusion as to what originally caused the error. Example, ssh server disconnects which prompts a cascade of events (conn.on('end'), socket.on('disconnect'), conn.on('close')) and the original reason (conn.on('end')) would be lost and the user would erroneously receive a WEBSOCKET error as the last event to fire would be the websocket connection closing from the app.
 - ensure ssh session is closed when a browser disconnects from the websocket
 - if headerBackground is changed, status background is changed to the same color (typo, fixed)
 ### Removed
 - Express Static References directly to module source directories due to concatenating and minifying js/css
 ## 0.0.5 - [2017-03-23]
 ### Added
 - Added experimental support for logging (see Readme)
 ### Fixed
 - Terminal geometry now properly fills the browser screen and communicates this to the ssh session. Tested with IE 11 and recent versions of Chrome/Safari/Firefox.
 ## 0.0.4 - [2017-03-23]
 ### Added
 - Set default terminal to xterm-color
 - Mouse event support
 - New config option, config.ssh.term to set terminal
 ### Changed
 - Update to Xterm.js 2.4.0
 - Minor code formatting cleanup
 ## 0.0.3 - [2017-02-16]
 ### Changed
 - Update xterm to latest (2.3.0)
 ### Fixed
 - Fixed misspelled config.ssh.port property
 ## 0.0.2 - [2017-02-01]
 ### Changed
 - Moving terminal emulation to xterm.js
 - updating module version dependencies
 ### Fixed
 - Fixed issue with banners not being displayed properly from UNIX hosts when only lf is used
 ## 0.0.1 - [2016-06-28]
 ### Added
 - Initial proof of concept and release. For historical purposes only.

 You will be prompted for credentials to use on the SSH server via HTTP Basic authentcaiton. This is to permit usage with some SSO systems that can replay credentials over HTTP basic.
 Alternatively in main for testing, you can send credentials via POST with the variables "username" and "userpassword".

+# Docker Instructions
 ## NOTICE
 Docker versions differ from what is in `main` and are release dependant. 
 Meaning billchurch/webssh2:latest is the latest official release. This does NOT sync with what is in `main` on this repo. `main` is development and will change until it gets a release tag. 
 On occasion, examples or instructions on `main` will drift from what is released. You should refer to the tag of the version you're using to ensure you are following the proper guidance.
 That being said the most current release version is [0.4.6](https://github.com/billchurch/webssh2/tree/0.4.6), see that tag for details.
 ## Instructions
 Some configuration options are available as [Environment Variables](#environment-variables). If there is a configuration option you require which does not have an environment variable please [open an issue requesting](../../issues/new/choose).
 [webssh2 images are available in docker hub](https://hub.docker.com/repository/docker/billchurch/webssh2).
 the `latest` tag will pull the most recent stable release, otherwise you can pull individual tags/releases/versions of this repo by using a particular version in the tag.

 # CONTRIBUTING
 As of 0.4.0, we're trying our best to conform to the [Airbnb Javascript Style Guide](https://airbnb.io/projects/javascript/). I'm hoping this will make contributions easier and keep the code readable. I love shortcuts more than anyone but I've found when making changes to code I've not looked at in a while, it can take me a few momements to deconstruct what was being done due to readbility issues. While I don't agree with every decision in the style guide (semi-colons, yuk), it is a good base to keep the code consistent.
 If you've not used it before, I recommend installing the [vscode extensions](https://blog.echobind.com/integrating-prettier-eslint-airbnb-style-guide-in-vscode-47f07b5d7d6a) for that and [Prettier](https://prettier.io/) and getting familiar. The autocorrections are great (especially if you hate dealing with semi-colons...)
 All contributions are welcome, all may not make it into a release... To increase the chances of your contribution making it into a release, try your best to conform to the style guides and targets of the project.
 # Tips
-* You can enable extended debug messages in the browser Java console using:
+* If you want to add custom JavaScript to the browser client you can either modify `./src/client.html` and add a **<script>** element, modify `./src/index.js` directly, or check out `webpack.*.js` and add your custom javascript file to a task there (best option).
  * `localStorage.debug = '*';` - Debug Everything (a lot of messages)
  * `localStorage.debug = 'WebSSH2';` - Debug potentially interesting WebSSH2 related messages (replaying credentials, resizing data, other control messages)
 * If you want to add custom JavaScript to the browser client you can either modify `./src/client.html` and add a **\<script\>** element, modify `./src/index.js` directly, or check out `webpack.*.js` and add your custom javascript file to a task there (best option).

 ## 0.4.0 [20210519]
 ### BREAKING

 - Dropping support for node versions under 14
 ### Changes
 - Removed HTML menu code from ./app/server/socket.js, the menu is now fully laid out in the ./app/client/src/index.html and the option elements are hidden by default. Not sure why it wasn't done this way from the start, but there it is.
 - Updated socket.io to v4.1.1

 ### CONTRIBUTING
 In this release, we're trying our best to conform to the [Airbnb Javascript Style Guide](https://airbnb.io/projects/javascript/). I'm hoping this will make contributions easier and keep the code readable. I love shortcuts more than anyone but I've found when making changes to code I've not looked at in a while, it can take me a few momements to deconstruct what was being done due to readbility issues. While I don't agree with every decision in the style guide (semi-colons, yuk), it is a good base to keep the code consistent.
 If you've not used it before, I recommend installing the [vscode extensions](https://blog.echobind.com/integrating-prettier-eslint-airbnb-style-guide-in-vscode-47f07b5d7d6a) for that and [Prettier](https://prettier.io/) and getting familiar. The autocorrections are great (especially if you hate dealing with semi-colons...)
 As of 0.4.0-testing-0, the client code is written in [TypeScript](https://www.typescriptlang.org/docs/handbook/typescript-in-5-minutes.html). It's not that much different from JavaScript, and the introduction strong typing will ultimately help to produce better code. Eventually we want to move the whole project to TypeScript but that make take a bit more time. Take a moment to look at ./app/client/src/js/index.ts to see what TypeScript looks like.
 ## 0.3.1 [20210513]
 ### BREAKING
 - Ability to configure CORS settings for socket.io see [#240](../../issues/240) for more information on how this may break existing deployments. Default settings in example `config.json` are currently permissive `http.origins: ["*:*"]` please note that if a `config.json` is not present, the default is `http.origins: ["localhost:2222"]

 ## 0.1.0 [2017-05-27]
 ### Added
 - This ChangeLog.md file
 - Support for UTF-8 characters (thanks @bara666)
 - Snyk, Bithound, Travis CI
 - Cross platform improvements (path mappings)
 - Session fixup between Express and Socket.io
 - Session secret settings in `config.json`
 - env variable `DEBUG=ssh2` will put the `ssh2` module into debug mode
 - env variable `DEBUG=WebSSH2` will output additional debug messages for functions
 and events in the application (not including the ssh2 module debug)
 - using Grunt to pull js and css source files from other modules `npm run build` to rebuild these if changed or updated.
 - `useminified` option in `config.json` to enable using minified client side javascript (true) defaults to false (non-minified)
 - sshterm= query option to specify TERM environment variable for host, valid strings are alpha-numeric with a hypen (validated). Otherwise the default ssh.term variable from `config.json` will be used.
 - validation for host (v4,v6,fqdn,hostname), port (integer 2-65535), and header (sanitized) from URL input
 ### Changed
 - error handling in public/client.js
 - moved socket.io operations to their own file /socket/index.js, more changes like this to come (./socket/index.js)
 - all session based variables are now under the req.session.ssh property or socket.request.ssh (./index.js)
 - moved SSH algorithms to `config.json` and defined as a session variable (..session.ssh.algorithms)
 -- prep for future feature to define algorithms in header or some other method to enable separate ciphers per host
 - minified and combined all js files to a single js in `./public/webssh2.min.js` also included a sourcemap `./public/webssh2.min.js` which maps to `./public/webssh2.js` for easier troubleshooting.
 - combined all css files to a single css in `./public/webssh2.css`
 - minified all css files to a single css in `./public/webssh2.min.css`
 - copied all unmodified source css and js to /public/src/css and /public/src/js respectively (for troubleshooting/etc)
 - sourcemaps of all minified code (in /public/src and /public/src/js)
 - renamed `client.htm` to `client-full.htm`
 - created `client-min.htm` to serve minified javascript
 - if header.text is null in `config.json` and header is not defined as a get parameter the Header will not be displayed. Both of these must be null / undefined and not specified as get parameters.
 ### Fixed
 - Multiple errors may overwrite status bar which would cause confusion as to what originally caused the error. Example, ssh server disconnects which prompts a cascade of events (conn.on('end'), socket.on('disconnect'), conn.on('close')) and the original reason (conn.on('end')) would be lost and the user would erroneously receive a WEBSOCKET error as the last event to fire would be the websocket connection closing from the app.
 - ensure ssh session is closed when a browser disconnects from the websocket
 - if headerBackground is changed, status background is changed to the same color (typo, fixed)
 ### Removed
 - Express Static References directly to module source directories due to concatenating and minifying js/css
 ## 0.0.5 - [2017-03-23]
 ### Added
 - Added experimental support for logging (see Readme)

 ### Added
 - Set default terminal to xterm-color
 - Mouse event support
 - New config option, config.ssh.term to set terminal

 - Update xterm to latest (2.3.0)
 ### Fixed
