MultiMC 0.4.12

See features and bugfixes planned for 0.4.12.

Previous releases

MultiMC 0.4.11

This release contains mainly a workaround for Minecraft 1.9 support and returned support for OSX 10.7.

IMPORTANT

  • GH-1410: MultiMC crashes on launch on OSX 10.7

    MultiMC didn't work on OSX 10.7 because of an oversight in build server setup. This has been fixed.

  • GH-1453: Minecraft 1.9 snapshots didn't download and launch properly

    This has been causes by a change on Mojang servers - the data is now stored in a different location and the files describing the releases have a different format. The required changes on MultiMC side aren't complete yet, but it's enough to get snapshots working.

    Full support for the new version file format will come in the next release.

  • MultiMC version file format was simplified

    Some undocumented and unused features were removed from the format. Mostly version patches that removed libraries, advanced library application and merging rules, and things of similar nature. If you used them, you used an undocumented feature that is impossible to reach from the UI.

Improvements

  • GH-1502: When the locally cached Minecraft version was deleted, the instance that needed it would have to be started twice

    This was caused by generating the list of launch instructions before the update. It is now fixed.

  • Version file issues are now reported in the instance's Version page.

    This doesn't apply to every possible issue yet and will be expanded upon in the next release.

MultiMC 0.4.10

Second hotfix for issues with wifi connections.

IMPORTANT

  • GH-1422: Huge ping spikes while using MultiMC

    Another day, another fix. The bearer plugins added in 0.4.9 didn't really help and we ran into more bugs.

    This time, the presence of the netowrk bearer plugins caused a lot of network lag for people on wifi connections.

    Because this wasn't a problem on the previous version of Qt MultiMC used (5.4.2), I ended up reverting to that. This is a temporary solution until the Qt framework can be rebuilt and retested for every platform without this broken feature.

    The upstream bug is QTBUG-40332 and despite being closed, it is far from fixed.

Because of the reverted Qt version, OSX 10.7 might work again. If it does, please do tell, it would help with figuring out what went wrong there :)

MultiMC 0.4.9

Hotfix for issues with wifi connections.

IMPORTANT

  • GH-1408: MultiMC 0.4.8 doesn't work on wireless connections.

    This is especially the case on Windows. If you already updated to 0.4.8, you will need to do a manual update, or use a wired connection to do the update.

    The issue was caused by a change in the underlying framework (Qt), and MultiMC not including the network bearer plugins. This made it think that the connection is always down and not try to contact any servers because of that.

    The upstream bug is QTBUG-49267.

  • GH-1410: MultiMC crashes on launch on OS X 10.7.5

    OSX 10.7.x is no longer supported by Apple and I do not have a system to test and fix this.

    So, this is likely NOT going to be fixed - please update your OS if you are still running 10.7.

Improvements

  • GH-1362: When uploading or copying the Minecraft log, the action is logged, including a full timestamp.

MultiMC 0.4.8

Fluffy and functional!

IMPORTANT

  • GH-1402: MultiMC will keep its binary filename after an update if you rename it.

    Note that this doesn't happen with this (0.4.8) update yet, because the old update method is still used.

    If you renamed MultiMC.exe for any reason, you will have to manually remove the renamed file after the update and rename the new MultiMC.exe.

    Future updates should no longer have this issue.

New features

  • GH-1047, GH-1233: MultiMC now includes basic Minecraft world management.

    This is a new page in the console/edit instance window.

    You can:

    • Copy worlds
    • Delete worlds
    • Copy the world seed value
    • Run MCEdit - the MCEdit feature has been moved here.

  • GH-1217: MultiMC now tracks instance play time and displays it when the instance is selected.

  • New buttons on the top toolbar:

  • GH-253, GH-1300: MultiMC can now be started with the -l "Instance ID" parameter, launching the specified instance directly.

Improvements

  • Instance list

    • GH-1121: Instances are now selected after you create them.
    • GH-93: When copying an instance, you can tell MultiMC to not copy the worlds.

  • Mod and resource pack lists

    • GH-1237: Mod info is now clickable and selectable.
    • GH-1322: Mod description ... link will no longer pop up multiple dialogs.
    • GH-1178: When dragged and dropped, folder based mods and resource packs will be copied properly on OSX.

  • MCEdit integration:

    • GH-1009: MCEdit Unified on linux is now recognized properly.

  • Mojang login and accounts:

    • GH-1158: An unique ID is generated on the MultiMC side before login, instead of letting the server decide.
    • When a password is required, the user login is partially obscured.
    • Dropdown menu on the main window now lists profiles, not accounts.

  • Modpacks:

    • GH-1140: Modpack downloads now check for update on the server even if the file is already locally available.
    • GH-1148: When creating an instance from modpack, the instance name will be guessed based on the modpack file or URL (unless you set it yourself).
    • GH-1280: While importing modpacks, the progress dialog now says what is happening.
    • When selecting the modpack field in the new instance dialog, the contents are selected for easy replacement.

  • Instance settings

    • Wrapper commands now use the proper UI field and do not get replaced with pre-launch commands.

  • Minecraft launching:

    • GH-1053, GH-1338: Minecraft launching has been completely redone.
    • GH-1275: Server resource pack folder is created on launch.
      • This is a workaround for Minecraft bug MCL-3732.
    • GH-1320: Improve compatibility with non-Oracle Java.
    • GH-1355: MMC environment will no longer leak into Minecraft after MultiMC updates itself.

  • Minecraft log:

    • Java exception detection in Minecraft logs has been improved.

    • GH-719: You can now use your own paste.ee account for uploading logs.

      • New paste.ee settings page has been added to the global settings dialog.

    • GH-1197: Text colors in log window now adapt to the background color.

    • GH-1164: The censor filter could be initialized with empty values, leading to unreadable log.

    • GH-1008, GH-1046, GH-1067: Log size limiting.

      The log window now has a configurable limit for the number of lines remembered. You can also specify whether it stops logging or forgets on the fly once the limit is breached.

      This prevents the MultiMC log window from using too much memory on logging. The default limit is 100000 lines and the logging stops.

      Minecraft logging this much is a sign of a problem that needs to be fixed. Any complaints should be addressed to the responsible mod authors.

  • Screenshot upload

    • GH-1339: While uploading screenshots, the console window will not close (prevents a crash).

  • Other logs:

    • GH-926: 'Other Logs' now has a button for removing all log files.
    • Hidden log files are shown in 'Other logs'.

  • User skins:

    • MultiMC now uses crafatar.com for skin downloads instead of the Mojang servers.

  • Java:

    • GH-1365: MultiMC now supports Java 9 and its new version numbering.
    • GH-1262: Java can now be placed in a folder relative to MultiMC's folder. This allows bundling of JREs with MultiMC.

  • Translations:

    • GH-1313: Some parts of the MultiMC user interface have been marked as 'not for translation'.

Internals and internal bug fixes

  • GH-1052: All the dependencies were rebuilt and the build environment upgraded to the latest compiler versions.

  • GH-1051: The CDPATH environment variable is now ignored.

  • GH-77, GH-1059, GH-1060: The MultiMC updater is no longer used or necessary.

    It is only present to preserve compatibility with previous versions. Updates now work properly on Windows systems when you have unicode (like ❄, Ǣ or Ω) characters in the path.

  • GH-1069, GH-1100: LD_LIBRARY_PATH and LD_PRELOAD environment variables supplied to MultiMC now don't affect MultiMC, but affect the launched game.

    This means you can use something like the Steam overlay in MultiMC instances on linux. If you need to use these variables for MultiMC itself, you can use MMC_LIBRARY_PATH and MMC_PRELOAD instead.

  • GH-1389: External processes (like folder views, editors, etc.) are now started in a way that prevents the MultiMC environment to be reused by them.

  • GH-1355: If LD_LIBRARY_PATH contains any of MultiMC's internal folders, this will not propagate to started processes.

  • GH-1231, GH-1378: libpng is now included with the linux version of MultiMC

  • GH-1202: SSL certificates are now rebuilt on start on OSX.

  • GH-1303: Translations and notification cache are stored in the normal data folder now, not alongside the binaries. This only affects third party linux packaging.

  • GH-1266, GH-1301: Linux runner scripts has been improved.

  • GH-1360: Development and other unstable versions of MultiMC now uses github commits instead of this manually maintained changelog.

0.4.7

This is what 0.4.6 should have been. Oh well, at least it's here now!

Functional changes

  • GH-974: A copy of the libstdc++ library is now included in linux releases, improving compatibility

  • GH-985: Jar mods are now movable and removable after adding

  • GH-983: Use minecraft.jar as the main jar when using jar mods - fixes NEI in Legacy Minecraft versions

  • GH-977: Fix FTB paths on Windows

    This removes some very old compatibility code. If you get any issues, make sure you run the FTB Launcher and let it update its files.

  • GH-992 and GH-1003: Improved performance when saving settings:

    • Bad performance was caused by improved data consistency
    • Each config file is now saved only once, not once for every setting
    • When loading FTB instances, there are no writes to config files anymore

  • GH-991: Implemented wrapper command functionality:

    There is an extra field in the MultiMC Java settings that allows running Java inside a wrapper program or script. This means you can run Minecraft with wrappers like optirun and get better performance with hybrid graphics on linux without workarounds.

  • GH-997: Fixed saving of multi-line settings. This fixes notes.

  • GH-967: It is now possible to add patches (Forge and LiteLoader) to tracked FTB instances properly.

    Libraries added by the patches will be taken from MultiMC's libraries folder, while the tracked patches will use FTB's folders.

  • GH-1011 and GH-1015: Fixed various issues when the patch versions aren't complete

    This applies when Minecraft versions are missing or when patches are broken and the profile is manipulated by adding, moving, removing, customizing and reverting patches.

  • GH-1021: Builtin legacy Minecraft versions aren't customizable anymore

    The internal format for Legacy Minecraft versions does not translate to the external patch format and would cause crashes

  • GH-1016: MultiMC prints a list of mods, coremods (contents of the coremods folder) and jar mods to the log on instance start. This should help with troubleshooting.

  • GH-1031: Icons are exported and imported along with instances

    This only applies if the icon was custom (not built-in) when exporting and the user doesn't choose an icon while importing the pack.

UI changes

  • GH-970: Fixed help button for the External tools and Accounts dialog pages not linking to the proper wiki places

    • Same for the Versions dialog page

  • GH-994: Rearranged the buttons on the Versions page to make jar mods less prominent

    Using the Add jar mods button will also show a nag dialog until it's been used successfully

0.4.6

Long time coming, this release brought a lot of incremental improvements and fixes.

Functional changes

  • Old version.json and custom.json version files will be transformed into a minecraft version patch:
    • The process is automated
    • LWJGL entries are stripped from the original file - you may have to re-do LWJGL version customizations

  • It's now possible to:
    • Customize, edit and revert builtin version patches (Minecraft, LWJGL)
    • Edit custom version patches (Forge, LiteLoader, other)

    • Export allows selecting which files go into the resulting zip archive
    • Only MultiMC instances for now, other pack formats are planned
    • Import is either from local file or URL, URL can't have ad/click/pay gates
  • Instance copy doesn't follow symlinks on Linux anymore
    • Still does on Windows because copying symlinks requires Administrator level access
  • Instance delete doesn't follow symlinks anymore - anywhere
  • MCEdit tool now recognizes MCEdit2.exe as a valid file to runtime
  • Log uploads now follow the maximum allowed paste sizes of paste.ee and are encoded properly
