API compatibility changes
v1.0.0 is the first GA release
GA: General Availability
V0 gems are very dangerous!
“Before a 1.0 release (version 0.x.y), the API can and
will be changing freely, without regard to the
restrictions detailed below.” - APR project versionings
“Major version zero (0.y.z) is for initial development.
Anything may change at any time. The public API
should not be considered stable.“ - Semantic Versioning
Does your v0 gem say?
“This gem is under development.”
NO: All gems are under development anytime!
Your v0 gem actually says:
will be broken about public APIs.”
will break your environment.”
is not appropreate to production environment.”
“The author doesn’t use this gem in production.”
Is it true?
If it’s false:
release v1 to express
not to break compatibilities.
