### Release Notes

<details>
<summary>webpack/webpack</summary>

### [`v5.50.0`](https://github.com/webpack/webpack/releases/v5.50.0)

[Compare Source](https://github.com/webpack/webpack/compare/v5.49.0...v5.50.0)

### Features

-   hashbangs (`#! ...`) are now handled by webpack
    -   https://github.com/tc39/proposal-hashbang

### Performance

-   disable cache compression by default as it tend to make performance worse
    -   I could still be enabled again for specific scenarios
-   reduce the number of allocations during cache serialization
    -   This improves performance and memory usage

### [`v5.49.0`](https://github.com/webpack/webpack/releases/v5.49.0)

[Compare Source](https://github.com/webpack/webpack/compare/v5.48.0...v5.49.0)

### Features

-   add `experiments.buildHttp` to build `http(s)://` imports instead of keeping them external
    -   keeps a `webpack.lock` file with integrity and `webpack.lock.data` with cached content that should be committed
    -   Automatically upgrades lockfile during development when remote resources change
        (might be disabled with `experiments.buildHttp.upgrade: false`)
    -   Lockfile is frozen during production builds and usually no network requests are made
        (exception: `Cache-Control: no-cache`).
    -   The `webpack.lock.data` persisting can be disabled with `experiments.buildHttp.cacheLocation: false`.
        That will will introduce a availability risk.
        (webpack cache will be used to cache network responses)

### Bugfixes

-   fix HMR infinite loop (again)
-   fix rare non-determinism with `splitChunks.maxSize` introduces in the last release
-   optional modules no longer cause the module to fail when `bail` is set
-   fix typo in records format: chunkHashs -> chunkHashes

### Performance

-   limit the number of parallel generated chunks for memory reasons
