3. Do you publish your gems?

4. Do you release
v1 or higher
of your own gems?

5. Versioning rules
Traditional versioning
sizes of differences between each ver.
just feeling
Semantic versioning
API compatibility changes

6. Common rule:
v1.0.0 is the first GA release
GA: General Availability

7. 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
2.0.0
http://apr.apache.org/versioning.html
http://semver.org/

8. Does your v0 gem say?
“This gem is under development.”
NO: All gems are under development anytime!

9. Your v0 gem actually says:
“This gem
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?

10. If it’s false:
Please,
release v1 to express
not to break compatibilities.

18. @t_wada:
“Thus, there is a romance in versioning. It’s interesting.”

19. Versioning is
a kind of (and very important)
communication.

20. How about fluentd?
Latest version of Fluentd is v0.10.x.
Will developers of Fluentd break compatibilities of
plugins or configuration files?

21. YES!!!
