Release 0.12.2 introduces breaking changes in ex-data behavior

[vedang]

Objects are no longer wrapped in a :object post e11c268, so any caller who parses the exception and runs ex-data on it gets an unexpected return value.

IMHO, the change itself is fine, but it should be clearly mentioned in the release notes / changelog as such so that upgrading to the latest version becomes simpler. Also, ideally this should be a Major version or at least a Minor version upgrade instead of a patch update.

I added a comment on the commit as well, but not sure how notifications on comments works. So opening an issue to track this.
