# MultiMC 0.6.2

## New or changed features

- MultiMC now has FTB integration:

  - Official and third-party modpacks work.
  - Codes for private modpacks are not implemented yet.

- Version lists now show release dates where available.

- New instance dialog:

  - It has been completely overhauled and now uses the same kind of paged dialog design as the rest of MultiMC.
  - Vanilla version list now has a filter for version types.
  - FTB integration gets a page here, along with zip import and vanilla.
  - Technic integration is a definite possibility in the future.
  - If there is a decent way to list Twitch modpacks, proper Twitch modpack integration is a possibility too.
  - There still is no modpack updating. Much more work is needed for that.

- Other Logs page:

  - Now has a search bar, just like the main log page.
  - GH-604: Uses the same font settings as the main log.

- Icon selection dialog now has a button for opening the icons folder.
- MultiMC now has a shinier, updated logo.
- GH-2150: Custom commands have been split from the java settings into a new page.

  The use of variables in custom commands is now better documented.
  The label shows that they need to be prefixed by `$`.

- Player name is no longer censored in logs.
- MultiMC now probes the system for the name of the linux distribution as part of analytics. This will be used to focus future packaging efforts.
- Secret cheat code has been added... What does it do?

## Bugfixes

- VisualVM integration now works when VisualVM is bundled inside the MultiMC folder (uses a relative path).
- When reinstalling a component, or changing a component version, the custom version is now removed first.
- GH-2134: Fix multiple issues with the skin upload:

  - When uploading a skin, the model selection now works correctly again.
  - When the new skin file is specified using the `file://` URL scheme, it will now work correctly.

- GH-2143: Mojang services status display now reflects the current set of services.
- GH-2154: MultiMC now ignores the `hidden` flag of instance folders and they should show up correctly.
- When migrating Legacy instances, custom `minecraft.jar` will be preserved.

# Previous releases

## MultiMC 0.6.1

### New or changed features

- GH-2087: The version page now has a button that will download all the necessary files without launching the game.

### Bugfixes

- Several issues related to bad URLs returned by the Curse servers have been fixed.

  The Curse platform does not use valid URLs according to [RFC 3986, section 2](https://tools.ietf.org/html/rfc3986#section-2) by including spaces and UTF-8 characters without percent encoding them.
  MultiMC has been improved to handle these invalid URLs and report errors in case other invalid URLs are encountered.
  This affected pretty much all modpack imports. You may want to reimport them if you were affected by this.

- GH-1780, GH-2102, GH-2103: Multiple issues with the build system and packaging on linux have been fixed.

  - Installed libraries now no longer have `RPATH` set and have the correct file permissions when using the `lin-system` layout.
  - Installation using the `lin-bundle` layout has been fixed on platforms that use position independent code.
  - `CMAKE_INSTALL_PREFIX` and `DESTDIR` now behave as expected on linux platforms.

- MultiMC no longer logs the process environment and launch scripts to its log files.

- GH-2089: Mention of instance tracking has been removed from the deletion confirmation dialog.

- GH-2087: The obsolete 'revert to vanilla' logic that was previously applied to versions has been removed.

  This should remove some confusing situations that could happen while changing and manipulation instance versions.

- The temporary `Minecraft.jar` is now removed from the instance after it stops running.

- GH-2119: The main instance view scrollbar now correctly updates when the window is resized without changing the number of icons that can fit into it horizontally.

## MultiMC 0.6.0

### New or changed features

- Contact with Mojang, Forge and LiteLoader servers is no longer handled by MultiMC, but a metadata server. Instead of generating and storing the files at the point of installation, they are updated hourly on the server and can be fixed when something goes wrong.

  This goes along with some changes to the instance format and to the metadata format.

  Instead of including the metadata JSON files directly in the instances, the instances now contain a new `mmc-pack.json` file that specifies versions to be used.

  The metadata can be found at [v1.meta.multimc.org](https://v1.meta.multimc.org), the [meta.multimc.org](https://meta.multimc.org) endpoint that was used during development will be replaced by documentation.

  This should be a much more reliable solution going forward, because it allows fixing issues without releasing new versions of MultiMC or reinstalling Forge/LiteLoader/others.

- Tracking of FTB launcher instances has been replaced with direct import of Curse modpacks.

  You can import the modpack zip files from CurseForge and FTB:
  - Get the zip, for example from [here](https://www.feed-the-beast.com/projects/ftb-retro-ssp/files/2219693).
  - Drag & Drop it on top of the main window, or select it in the new instance dialog.
  - Let the magic happen.

  If you need help moving over your old instances or worlds from the FTB launcher, stop by in the MultiMC discord server.

  The Curse import functionality is there thanks to the work [@Dries007](https://twitter.com/driesk007) and [@NikkiAI](https://twitter.com/NikkyAI) have done on [CurseMeta](https://cursemeta.dries007.net/).

- GH-1314: MultiMC now allows replacing the main jar in an instance without having to mod the Mojang jars.

  This goes along with changing the wording of the jar mod button to make it clear that it adds files to the main Minecraft jar instead of installing mod files with the `.jar` extension.

- Because the current instance format can now handle replacing the main jar, Legacy format instances are no longer directly supported.

  Instead of launching, you will be prompted to convert them to the current instance format.
  If the automated process fails, stop by in the MultiMC discord server and ask for help.

- Main window UI has been changed for increased clarity.

  Many people had issues finding the settings and instead ended up using the per-instance overrides. The main toolbar now has labels and the per-instance overrides have been deemphasized by removing the direct path to them from the main window. In general, it should be easier to find the right settings menu without getting things completely wrong on the first try.

- GH-1997: MultiMC now supports Java 9.

  This does not mean that the current mod loaders and mods do, but you can run Vanilla Minecraft with Java 9 now.

  However, Java 9 will come up last in the lists when multiple versions are installed and its use is strongly discouraged.

- GH-2026: You can launch Minecraft 1.13 snapshots - and hopefully also 1.13 once it is released.

  The bare minimum of changes needed for 1.13 to launch has been done.

  This does not mean support for modded 1.13!

  It is not yet clear what it will even look like and what exactly will be needed for Forge to be able to install properly.

- Bundled Qt libraries have been updated to version 5.6.3 on macOS and Windows

  This means less issues with SSL encryption on macOS and better support for HiDPI/retina displays, along with many bug fixes.
  The workarounds for SSL problems on macOS have been removed thanks to this.

- Linux builds were moved to a newer version of Ubuntu (14.04)

  This means better support on newer distribution releases, and dropping support for older distributions.

- Bundled OpenSSL library on Windows no longer requires Visual Studio runtime libraries.

  This should avoid issues with missing runtime libraries.

- GH-1855: The instance window now has an offline launch button.

- GH-1886: UI now clarifies that MultiMC proxy settings do not apply to the game.

- It is now possible to package MultiMC on linux without hacks.

  The build system has a concept of 'install layouts'. Example Arch linux package that uses this (multimc-git) is [available in the AUR](https://aur.archlinux.org/packages/multimc-git).

- Wrapper commands now support arguments.

  Previously, they would be treated as a single command -- spaces and all.

- UI elements that set maximum JVM memory are now limited to the amount of system memory present.

  Before, they were hardcoded.



  This is to accommodate the needs of some new mods for ancient Minecraft versions that do not work well with the applet wrapper.

- On instance launch, the used GPU and graphics driver are reported - but only on linux.

  Other platforms will hopefully get this in the future.

- There are some under the hood improvements for ancient Minecraft versions and versions not provided by Mojang.

    - The `haspaid` parameter is set for the applet wrapper.
    - MultiMC will prefer to use `.minecraft` instead of `minecraft` folder inside the instances now.
    - There is some preliminary support for classic multiplayer - see [this workflowy list](https://workflowy.com/s/2EyDMcp7CU#/1cbfc198cf28) for details.
    - A new `noapplet` trait has been added to allow running legacy Minecraft versions without the applet wrapper.

- Mods without changed metadata (Example Mod) are now listed under their filename instead.

- Tweaker list in metadata now overrides the order of already present tweakers.

  This allows running [Vivecraft](http://www.vivecraft.org/). Official support will hopefully follow.

- Instance icons can now be in the SVG format. Also, aspect ratio of SVG icons is now preserved in the instance toolbar.

- GH-1082: It is now possible to disable and enable version components (packages) similarly to mods.

- A new material design / flat icon theme has been added.

- When changing instance component versions, the present version is selected first.

### Bugfixes

- paste.ee upload now works again.

  MultiMC now uses its new API. If you used a custom API key before, you will need to generate a new one.

- GH-1873, GH-1873, GH-1875 : The main window can now be closed regardless of running instances and running instances directly will not create a main window.

- GH-1854: MultiMC should no longer crash when the instance is closed while the kill confirmation dialog is open.

- GH-1956: Launch will abort sooner when important files are missing.

- GH-1874: Instance launching and updating MultiMC are now mutually exclusive.

  It was possible to do both at the same time, with undefined results.

- GH-1864: imgur album creation now works again.

- GH-1876: Various included libraries have been changed to satisfy their license terms.

  Namely:
  - pack200 (GPL with classpath exception, now a shared library)
  - iconfix (LGPL, now a shared library)
  - quazip (LGPL, now a shared library)
  - ColumnResizer (replaced with a BSD-3 version).

- GH-1882: Update dialog will now save its location and size.

- GH-1885: MultiMC will now correctly download zero-byte files.

  No content does not equal no file and a presence of a file can mean the difference between something working or not.

- When importing modpacks, file permissions from the pack archive will no longer be preserved.

  The archives are sometimes broken and have invalid permissions, especially when coming from sources other than MultiMC.

- Instance export filter has been fixed.

  The filtering logic was picking and ignoring incorrect files under some conditions. Also, hidden files were ignored.

- Download progress bars are now less jumpy.

  Instead of tracking the total size of all downloads, each download gets a fixed share of the progress bar.
  In many cases, the size of files is unknown before a download starts. The change means that the total progress bar size cannot increase as new downloads start and file sizes are discovered.

- GH-1927: fix crash bugs related to FML library downloads succeeding multiple times.

- Rare problems with error 201 during Mojang authentication have been fixed.

- GH-1971: MultiMC will now no longer check path prefixes when importing instances.

  This has caused more issues than it solved. Now it will simply try to move the files instead of giving up early.

- Instance import and creation have been overhauled in general for increased reliability.

- Hardcoded link colors in various dialogs and dialog pages have been fixed and now should follow theme palettes.

- GH-1993: Minimum and maximum JVM memory settings will now get swapped if set the wrong way.

  The values self-correct on both settings save and load now.

- GH-2050: Fixed behavior of cancel buttons when browsing for paths.

  This affected various settings dialogs and pages, setting the paths to an invalid value when the dialogs were closed with the `Cancel` button.

- The checkboxes in the accounts settings page now have the correct appearance.

- MultiMC responds to account manipulation better.

    - Setting and resetting default account will update the account list properly.
    - Removing the active account will now also reset it (previously, it would 'stay around').
    - The accounts model is no longer reset by every action.

- When closing and reopening the instance window, the log settings are preserved.

- In the instance export dialog, the sorting order has been changed to go from `a` to `z`, not backwards.

## MultiMC 0.5.1

### Improvements

- Log uploads now use HTTPS because the [paste.ee](https://paste.ee) site is switching to HTTPS only.

- Console now has the line limit and overflow settings properly set when hidden.

  Before, if you didn't have the console set to show up on launch, it would have some low default values set.
  This meant that you wouldn't get enough of the log when the game crashed.

- GH-1802: Log resize is now handled properly.

  The log could end up with many empty lines because the wrong maximum size was used during the resize, potentially losing some lines.

- GH-1807: Fixed 'loggging' typo in console overflow notification.

- GH-1801: Launch script is no longer dumped into MultiMC's log on instance launch.

- GH-1065: Use of 'folder' and 'directory' in the UI has been unified to 'folder'.

- GH-1788: A problem with missing translation templates in the setup wizard pages has been fixed.

  It should be possible to translate everything again.

- GH-1789: Deletion of custom icon has been fixed.

  It wasn't possible to do it from the MultiMC icon selection dialog.

- GH-1790: While using the system theme on macOS, dialogs had wrong colors.

  The wrong colors are now only visible immediately after changing the theme to 'System'. An application restart will fix the colors.

  The underlying issue cannot be easily fixed.

  Upstream bug: https://bugreports.qt.io/browse/QTBUG-58268

- GH-1793: The Java wizard page did not show up as expected when moving MultiMC between different computers.

  The page should now show up as expected.

- GH-1794: Copied FTB instances did not work properly.

  The instance type of the copy was not set, causing it to not be usable.

## MultiMC 0.5.0

### New or changed features

- GH-338, GH-513, GH-700: Edit instance dialog and Console window have been unified

  The resulting instance window can be closed or reopened at any point, it does not matter if the instance is running or not. The list of available pages in the instance window changes with instance state.

  Multiple instances can now run from the same MultiMC - It's even more **multi** now.

  On launch, the main window is kept open and running instances are marked with a badge. Opening the instance window is no longer the default action. Second activation of a running instance opens the instance window.

  MultiMC can be entirely closed, keeping Minecraft instances running. However, if you close MultiMC, play time tracking, logging and crash reporting will not work.

  Accounts which are in use are marked as such. If you plan to run multiple instances with multiple accounts, it is advisable to not set a default account to make it ask which one to use on launch.

- It is no longer possible to run multiple copies of MultiMC from a single folder

  This generally caused strange configuration and Mojang login issues because the running MultiMC copies did not know about each other.

  With the ability to launch multiple instances with different accounts, it is no longer needed.

  Trying to run a second copy will focus the existing window. If MultiMC was started without a main window, a new main window will be opened. If the second copy is launching an instance from the command line, it will launch in the first copy instead.

  This feature is also used for better checking of correct update completion (GH-1726). It should no longer be possible for MultiMC to end up in a state w
