### Releases
### Releases and API Stability
containerd will be released with a 1.0 when feature complete and this version will be supported for 1 year with security and bug fixes applied and released.
The upgrade path for containerd is that the 0.0.x patch releases are always backward compatible with its major and minor version.
Minor (0.x.0) version will always be compatible with the previous minor release. i.e. 1.2.0 is backwards compatible with 1.1.0 and 1.1.0 is compatible with 1.0.0.
There is no compatibility guarantees with upgrades from two minor releases. i.e. 1.0.0 to 1.2.0.
There are not backwards compatibility guarantees with upgrades to major versions. i.e 1.0.0 to 2.0.0.
Each major version will be supported for 1 year with bug fixes and security patches.
Please see [RELEASES.md](RELEASES.md) for details on versioning and stability
of containerd components.

This directory contains the GRPC API definitions for containerd.
All defined services and messages have been aggregated into `*.pb.txt`
descriptors files in this directory. Definitions present here are considered
frozen after the release.
At release time, the current `next.pb.txt` file will be moved into place to
freeze the API changes for the minor version. For example, when 1.0.0 is
released, `next.pb.txt` should be moved to `1.0.txt`. Notice that we leave off
the patch number, since the API will be completely locked down for a given
patch series.
We may find that by default, protobuf descriptors are too noisy to lock down
API changes. In that case, we may filter out certain fields in the descriptors,
possibly regenerating for old versions.
This process is similar to the [process used to ensure backwards compatibility
in Go](https://github.com/golang/go/tree/master/api).
