// These constants determine the current version of this module.
|
||
|
//
|
||
|
// For our release process, we enforce the following rules:
|
||
|
// - Tagged releases use a tag that is identical to String.
|
||
|
// - Tagged releases never reference a commit where the String
|
||
|
// contains "devel".
|
||
|
// - The set of all commits in this repository where String
|
||
|
// does not contain "devel" must have a unique String.
|
||
|
//
|
||
|
// Steps for tagging a new release:
|
||
|
//
|
||
|
// 1. Create a new CL.
|
||
|
//
|
||
|
// 2. Update Minor, Patch, and/or PreRelease as necessary.
|
||
|
// PreRelease must not contain the string "devel".
|
||
|
//
|
||
|
// 3. Since the last released minor version, have there been any changes to
|
||
|
// generator that relies on new functionality in the runtime?
|
||
|
// If yes, then increment RequiredGenerated.
|
||
|
//
|
||
|
// 4. Since the last released minor version, have there been any changes to
|
||
|
// the runtime that removes support for old .pb.go source code?
|
||
|
// If yes, then increment SupportMinimum.
|
||
|
//
|
||
|
// 5. Send out the CL for review and submit it.
|
||
|
// Note that the next CL in step 8 must be submitted after this CL
|
||
|
// without any other CLs in-between.
|
||
|
//
|
||
|
// 6. Tag a new version, where the tag is is the current String.
|
||
|
//
|
||
|
// 7. Write release notes for all notable changes
|
||
|
// between this release and the last release.
|
||
|
//
|
||
|
// 8. Create a new CL.
|
||
|
//
|
||
|
// 9. Update PreRelease to include the string "devel".
|
||
|
// For example: "" -> "devel" or "rc.1" -> "rc.1.devel"
|
||
|
//
|
||
|
// 10. Send out the CL for review and submit it.
