Breaking Changes

●Issue #1

Typer no longer depends on Click as a third party dependency; it now vendors (includes the source code of) Click. This means Click-specific functionality is no longer supported, such as extracting the Click app, adding Click-specific plug-ins, or customizing field types with Click-specific types.

Migration Steps

  1. 1
    If you relied on Click-specific functionality (like extracting the Click app or using Click-specific plug-ins/types), you must refactor your code as this functionality is no longer supported due to Click being vendored internally.

Release Summary

Typer has transitioned to vendoring the Click library internally, removing the external dependency on Click. This change simplifies dependency management but removes support for Click-specific extensions and functionality.
