  • Now crash assistant supports mclo.gs logs deletion feature. You can see/remove previously uploaded logs from mclo.gs servers from our gui.
  • Updated privacy policy with feature description.
  • New Piracy warning. Checks if user is using piracy version of the game or offline mod and warns them that they won't receive support in Discords where it's not allowed. Modpacks need to enable this feature manually piracy.enabled. This is enabled by default only for individual downloads.
  • Now generated message will also have notification about piracy (configurable).
  • Added a delay to the OK button for the first time analysis messages are shown. The default is 10 seconds, as users who ignore the analysis typically decide not to read it and close the window within the first 10 seconds.
  • Crash Assistant log will have JVM args of the game and launcher args of the game. Confidential info is censored.
  • Fixed ResourceLocationException analysis sometimes doesn't work.
  • Fixed bracket symbols in path of modpack on MinecraftForge 1.21.1+ causing Crash Assistant not starting issue. However, updating forge is also needed since same issue was on side of modloader.
  • Limited concurrent log uploads in McLogsApi to prevent 429 error in case of very many logs.
  • Refactored McLogsApi to prevent multiple requests to get insights. Now it gets insights from upload response.
  • Now .crash_assistant_tmp folder is removed on exit from app.
  • Separated LogType.STDERR_STREAM from LogType.LAUNCHER_LOG.
  • Add logging for successful uploads of log and modlist links. Now if user was confused and only shared just the Crash Assistant log, we can still have links to others.
  • Added some other logging.
  • Renamed Untrusted Link Domain to Link Opening Confirmation to make it less confusing for users.
  • Simplified and shortened Upload All button text.
  • Added new analysis SimpleCloudsShaders, detects conflict between simple clouds, distant horizons and shaders.
  • Added new analysis PhysX_64, detects if crash is caused by physics mod.
  • Added new analysis IrlandaCoreBackDoor, warns about creative mode backdoor for author in mod.
  • Added new analysis WaterMediaVLCMissing, detects crash caused by missing VLC libs.
  • Added new analysis ModernIntelDriverIssue, detects crash caused by an Intel driver.
  • Enabled mixin apply analysis for modpack end users.
    • By default, we will trigger only on the mods added by end users of the modpack. You can configure it so analysis will display anyways and will trigger also on mods which were originally in the modpack.
    • Removed config parameter BYPASS_MODPACK_CHECK_FOR_MIXIN_APPLY, since it no longer needed.
  • Now ModuleResolution analysis also detects mixinextras.neoforge on forge issue and recommends mod created to fix issue (Mixin Extras NeoForge on Forge Fix).
  • Added general.formulation_type configuration option, allowing to choose between Discord and GitHub formulation for the top-of-window text and help buttons. If set to GITHUB, terminology like "visit the GitHub" and "Report the issue on GitHub" will be used instead of Discord-specific ones.
  • Generated Message Customisation:
    • Implemented full control over the "Upload All" message structure: users can now rearrange or modify message elements (Header, Logs, Analysis, etc.) using config patterns.
    • Added formatting patterns: customizable templates for individual log lines, split logs, link notifications, and ANSI blocks. Now you can disable markdown formatting.
    • Replaced restrictive options: h3_prefix and one_line_logs booleans are replaced with flexible string templates (prefix, logs_separator) to allow any formatting style.
  • 1.7.10: fixed crash assistant starting on lwjgl3ify relaunch.
