## Executive Summary (TL;DR)
Helm v2.13.0. Source highlight: Helm v2.13.0 is a feature release. This release, we focused on stability and a few key features to enhance the usability of Helm. Users are encouraged to upgrade for the best experience.

## Breaking Changes & Deprecations
- Breaking Changes In this release, we made a backwards-incompatible change to the gRPC API. To avoid backward compatibility breakers, we have been pinned to a very old version of gRPC for some time. Recent versions of gRPC fixed some significant networking fixes with TLS connection handling, but it required us to regenerate a few of the proto files, so some parts of the binary wire format may be broken in backwards-incompatible ways.

## New Features
- introduced `--atomic` to `helm install` and `helm upgrade` which restores the previous state in case of a failed install/upgrade attempt
- introduced `--render-subchart-notes` to `helm install` and `helm upgrade` which renders all of the subcharts' notes
- introduced `--devel` to `helm inspect` to inspect pre-release versions of Helm charts similar to `helm fetch --devel`
- introduced `--parallel` to `helm test` for running multiple tests in parallel
- introduced a check for a valid chart name on `helm lint`
- v2.14.0 is the next feature release.

## Improvements
- Improve language describing deletion of hooks (#5065) 16c10be8e652165414eef007be3f57638d6894cf (Henry Nash)
