Release Notes

earthly/earthly

### [`v0.6.27`](https://togithub.com/earthly/earthly/blob/HEAD/CHANGELOG.md#v0627---2022-10-17) [Compare Source](https://togithub.com/earthly/earthly/compare/v0.6.26...v0.6.27) ##### Changed - Support for all ssh-based key types (e.g. ssh-ed25519), and not only ssh-rsa. [#​1783](https://togithub.com/earthly/earthly/issues/1783) ##### Fixed - Unable to specify public key to add via the command-line, e.g. running `earthly account add-key ` ignored the key and fellback to an interactive prompt. - `GIT CLONE` command was ignoring the `WORK DIR` command when `--use-copy-link` feature was set.
