webpack v4.38.0 Release Notes

Release Date: 2019-07-26 // almost 5 years ago

  • 🐎 Performance

    • 👌 Improved performance of ProgressPlugin
    • 👌 Improved performance of chunk graph generation
      • This can boost performance when many chunks are used, especially incremental build performance
      • Modules from parent chunks are now tracked during chunk graph generation, which allows to skip these modules in async chunks. This often renders optimization.removeAvailableModules unneeded, expect in scenarios where chunks are merged during optimization.
    • 🚚 optimization.removeAvailableModules is now disabled in development mode by default
      • optimization.removeAvailableModules will be disabled for all modes in next major release, feel free to disable it in production too if you want extra performance.
