Performance boost for virtual file systems
In June 2023 Mutagen IO, Inc. was acquired by Docker Inc. The company is behind Mutagen’s open-source file synchronization and networking technologies to enable high-performance remote development. Now Docker has integrated mutagen technology into the core of Docker Desktop and enables synchronized file shares.
This is intended to address the difficulties encountered with large code bases in containers with virtual file systems. Synchronized file shares are intended to enable native file system performance for bind mounts and speed up file system calculations by two to ten times. The feature, described by the development team as a game changer, is in the Paid Pro, Team and Business subscriptions available.

It has been on board since Docker 4.18 and is used to help initialize Docker resources within a project, for example by automatically creating Dockerfiles and Compose files.
Since its creation has docker init Some features have been added, for example support for Python and Node.js was added last year. In addition to these and the original programming language Go can docker init now working with Rust, ASP.NET, PHP and Java.
