0.41.14-rc1

(feat): Running fern check will now check to confirm that the generator versions you are running are compatible with your Fern CLI version.

Each version of SDK generators depends on a version of a library that is exported by the Fern CLI, and as a result, each generator has a minimum compatible version of the Fern CLI. As an example, if you were to run fern check while leveraging fernapi/fern-python-sdk version 2.0.0, on CLI version 0.1.3, you’d receive the following error:

The generator fernapi/fern-python-sdk requires CLI version 0.23.0-rc4 or later (current version: 0.1.3-rc0).

Indicating that you must upgrade your CLI in order to leverage the current generator.

What’s new

  • Running fern check will now check to confirm that the generator versions you are running are compatible with your Fern CLI version.
  • Fern commands now print out generator upgrades, in addition to CLI upgrades.
