Release Notes

spf13/cobra

v1.1.1

Compare Source

• Fix: yaml.v2 2.3.0 contained a unintended breaking change. This release reverts to yaml.v2 v2.2.8 which has recent critical CVE fixes, but does not have the breaking changes. See #​1259 for context.
• Fix: correct internal formatting for go-md2man v2 (which caused man page generation to be broken). See #​1049 for context.
