How to update the version after removal of a licence

help
1

I want to remove the licence: Unlicense from my library (probably sleepy during editing :disappointed: )

  • How to update my version number?
  • And should I yank the current version(s)?

According to rust semver :

"Changing the license of an open source crate is an incompatible change: users of your crate who have strict restrictions on what licenses are acceptable may be broken by the change. Consider the license to be part of your API."

Current situation:

  • license = "Unlicense OR MIT OR Apache-2.0" (Cargo.toml)
  • version = "1.0.0+doc" (Cargo.toml)
  • There is NO licence file for Unlicense.
  • There is NO mention of Unlicense in the README.

New situation:

  • license = "MIT OR Apache-2.0" (Cargo.toml)
  • version = "2.0.0" (Cargo.toml) OR version = "1.1.0" OR something else ???
  • all older versions yanked ???

Given all three licenses are permissive, I personally would remove the Unlicense from the manifest and release 2.0.0. Never tried this before though—I don't know whether crates.io permits changes to the license field between versions, but I expect it does.

Thanx for the help.
Just published my crate with a modified licence field.
No errors or warnings were reported during the process.

it sure does. in the database, there's no license column in the crates table, the license column is actually in the versions table:

I happened to notice this the other day, when I was doing some analysis of the database dump:
