 Minetrack is a Minecraft PC/PE server tracker that lets you focus on what's happening *now*. 
 Built to be lightweight and durable, you can easily adapt it to monitor BungeeCord or server instances.
 
+#### Migrating to Minetrack 5
+See our Minetrack 5 [migration guide](docs/MIGRATING.md).
+
 #### This project is not actively maintained!
 This project and the offical website are not actively maintained anymore, but you are welcome to run your own instances of Minetrack.
 I will however review and accept pull-requests, so please share any improvements you are making so everybody can benefit from them.

+**5** *(Apr 8 2020)*
+- New logo!

+- Adds a button for mobile devices to manually request the historical graph
+- Adds timestamp to each server's player count record
+- Adds the ability to favorite servers so they'll always be sorted first
+- Adds "Sort By" option for controlling the server listing sort order
+- Adds "Only Favorites" button to graph controls
+- Adds ESLint configuration
+- New missing favicon icon

+- Removes "routes" from config.json. The HTTP server will now serve static assets from dist/
+- Added Parcel bundler which bundles the assets/ directory into dist/ 
+- Custom favicons are now served from "favicons/" directory and their configuration moved into servers.json. Paths in servers.json should be updated to reflect their filename without the path.
+- Added finalhandler and serve-static dependencies
+- Add ```npm run dev``` and ```npm run build``` scripts to package.json
+- Added a distinct loading/connection status screen to simplify state management
+- publicConfig.json is now sent over the socket connection so the frontend can be safely reloaded on rebooted instances
+- Tooltips have been optimized and updated to a more readable design
+- Initial page loading has been optimized
+- MISSING_FAVICON_BASE64 has been moved to a file, images/missing_favicon.svg to improve caching behavior (and its customizable now!)

+- Fixed status text ocassionally not being shown
+- Fixed some elements/frontend state not being completely reset on disconnect
+- Fixed Minecraft Bedrock Edition servers showing the default port of 19132
+- Fixed tooltips overflowing the page width
+- Fixed backend bug causing servers to skip some Minecraft versions
+- Minor connection blips have a grace period before the UI is updated, this prevents page reshuffle spam when experiencing minor connection issues
+- Moved localStorage keys to "minetrack_hidden_servers" since the data structure has been changed
+- Removed #validateBootTime loop and logic

+# Migrating to Minetrack 5
+Minetrack 5 is the first of several upcoming updates designed to address several legacy bugs and design flaws in previous Minetrack versions. As part of this, it modifies some data structures and operational instructions that make the upgrade process more manual than seen previously. This guide covers the distinct differences, with upgrade instructions, to get you started.
+
+## Upgrading Minetrack 5
+1. Stop any running instance of Minetrack.
+2. If you've cloned the repository, use `git clone https://github.com/Cryptkeeper/Minetrack Minetrack5`. If you've manually downloaded a release or an archive of the repository, download a fresh copy and extract it into a directory named "Minetrack5".
+3. Open the directory and execute `npm install --build-from-source`. This will install updated (and new) dependencies needed by the program.
+4. If you have `logToDatabase: true` in your `config.json`, make sure to copy your `database.sql` file into the new directory, otherwise you will lose historical server activity and records.
+5. Copy your existing `config.json` and `servers.json` files into the new directory.
+4. Build your copy of `dist/`.
+5. If you have previously configured any `faviconOverride` values within `config.json`, you will need to move them to the updated structure. Create a new directory within your Minetrack folder named `favicons/`.
+6. If you have previously configured any `minecraft.json` values not included in the new `minecraft_versions.json` file, you will need to update their structure copy them to the new file.
+7. Move your custom favicon images into the directory. 
+8. Open `servers.json` in your favorite editor.
+9. For any server which you have a custom favicon, set the "favicon" field like so:
+
+```
+{
+	"name": "Hypixel",
+	"ip": "mc.hypixel.net",
+	"type": "PC",
+	"favicon": "CustomHypixelFavicon.png"
+}
+```
+(Replacing "CustomHypixelFavicon.png" with your file's name.)
+
+Do **NOT** include the `favicons/` path in the value. For example a file, "my-favicon.png" in the directory `favicons/` should be configured using simply "my-favicon.png".
+
+You may delete the `faviconOverride`, `routes` and `versions` portions of your `config.json`, they are no longer supported features. You may delete the `minecraft.json` file, it has been merged into `minecraft_versions.json`.
+
+You're done!
+
+## Building `dist/`
+Minetrack now serves a "bundled" copy of the `assets/` directory, instead of the files directly from disk. This optimizes the delivery speed, but requires an additional step when installing Minetrack or when modifying files within `assets/`.
+
+1. `cd` into your Minetrack directory (if not already there).
+2. Execute `npm run build` (`npm run dev` is also available, which skips the minimization step and makes active development easier).
+3. Run `ls` to ensure the `dist/` directory has been created.
+
+Whenever modifying files within `assets/`, you will need to re-run the `npm run build` step to reflect the changes. Those expert few of you may wish to dig into Parcel's [watch and serve](https://parceljs.org/cli.html#watch) CLI commands.
