-## Important note about releases, versioning, tagging, and stability
+## Important note about releases and stability
 
-In this repository, we used to mostly ignore the many coming and going
-dependency management tools for Go and instead wait for a tool that most of the
-community would converge on. Our bet is that this tool has arrived now in the
-form of [Go
-Modules](https://github.com/golang/go/wiki/Modules#how-to-upgrade-and-downgrade-dependencies).
+This repository generally follows [Semantic
+Versioning](https://semver.org/). However, the API client in
+prometheus/client_golang/api/… is still considered experimental. Breaking
+changes of the API client will _not_ trigger a new major release. The same is
+true for selected other new features explicitly marked as **EXPERIMENTAL** in
+CHANGELOG.md.
 
-To make full use of what Go Modules are offering, the previous versioning
-roadmap for this repository had to be changed. In particular, Go Modules
-finally provide a way for incompatible versions of the same package to coexist
-in the same binary. For that, however, the versions must be tagged with
-different major versions of 1 or greater (following [Semantic
-Versioning](https://semver.org/)). Thus, we decided to abandon the original
-plan of introducing a lot of breaking changes _before_ releasing v1 of this
-repository, mostly driven by the widespread use this repository already has and
-the relatively stable state it is in.
-
-To leverage the mechanism Go Modules offers for a transition between major
-version, the current plan is the following:
-
-- The v0.9.x series of releases will see a small number of bugfix releases to
-  deal with a few remaining minor issues (#543, #542, #539).
-- After that, all features currently marked as _deprecated_ will be removed,
-  and the result will be released as v1.0.0.
-- The planned breaking changes previously gathered as part of the v0.10
-  milestone will now go into the v2 milestone. The v2 development happens in a
-  [separate branch](https://github.com/prometheus/client_golang/tree/dev-v2)
-  for the time being. v2 releases off that branch will happen once sufficient
-  stability is reached. v1 and v2 will coexist for a while to enable a
-  convenient transition.
-- The API client in prometheus/client_golang/api/… is still considered
-  experimental. While it will be tagged alongside the rest of the code
-  according to the plan above, we cannot strictly guarantee semver semantics
-  for it.
+Features that require breaking changes in the stable parts of the repository
+are being batched up and tracked in the [v2
+milestone](https://github.com/prometheus/client_golang/milestone/2). The v2
+development happens in a [separate
+branch](https://github.com/prometheus/client_golang/tree/dev-v2) for the time
+being. v2 releases off that branch will happen once sufficient stability is
+reached. In view of the widespread use of this repository, v1 and v2 will
+coexist for a while to enable a convenient transition.
