# Changelog

All notable changes to this project are documented in this file.

## 0.6.1

**Release date:** 2021-01-14

This prerelease fixes a regression bug introduced in `v0.6.0` that caused
reconciliation request annotations to be ignored in certain scenarios.

## 0.6.0

**Release date:** 2021-01-12

This is the sixth MINOR prerelease, upgrading the `controller-runtime`
dependencies to `v0.7.0`.

The container image for ARMv7 and ARM64 that used to be published
separately as `source-controller:*-arm64` has been merged with the
AMD64 image.

## 0.5.6

**Release date:** 2020-12-18

This prerelease fixes a regression bug that made it impossible to
reference to a `HelmChart.ValuesFile` in a path relative to the
root of the `Bucket` or `GitRepository` source.

## 0.5.5

**Release date:** 2020-12-16

This prerelease adds safe guards for user defined relative paths,
ensuring they never traverse outside working directories.

Other notable changes:

* ListObjects V1 fallback for GCS S3 endpoints, ensuring generic
  `Bucket` resources connecting to GCS are able to list object
* HelmChart controller panic regression bug fix, introduced in
  `v0.5.0`

## 0.5.4

**Release date:** 2020-12-12

This prerelease fixes a bug in the build process that caused the
ARMv7 image to fail due to `libgit2` requiring `musl>=1.2.0`.

## 0.5.3

**Release date:** 2020-12-11

This prerelease fixes a regression bug causing the commit hash for the
`go-git` implementation to not be forwarded, introduced by the support
for multiple Git implementations. 

## 0.5.2

**Release date:** 2020-12-11

This prerelease adds the option to configure the advertised storage
address using the `--storage-adv-addr` flag.

The default deployment manifest uses this to configure the FQDN of
the service (`source-controller.$(RUNTIME_NAMESPACE).svc.cluster.local.`),
but omitting the flag will result in a fallback to the previous behavior
for backwards compatibility.

## 0.5.1

**Release date:** 2020-12-09

This prerelease fixes a bug in the build process that caused the
ARMv7 build to fail due to `libgit2` requiring `musl>=1.2.0`.

## 0.5.0

**Release date:** 2020-12-09

This is the fifth MINOR prerelease, adding a new Git implementation
(`libgit2`) to allow for communication with Git servers that just
support the Git v2 protocol, like Azure Devops.

The new Git implementation can be enabled by configuring the
`GitImplementation` in a `GitRepository` to `libgit2` (default:
`go-git`). Note that this implementation does not support shallow
cloning, and it is therefore advised to only resort to this option
if a connection fails with the default configuration.

Other notable changes in this release:

* Bug fix to respect the configured SSH user in `GitRepository` URLs
* Chart name validation for charts from a `HelmRepository` resource
* Kubernetes dependency upgrades to `v1.19.4`
* Helm upgrade to `v3.4.2`

## 0.4.1

**Release date:** 2020-11-26

This prerelease fixes a bug in the listing of HelmChart resources
for GitRepository changes.

## 0.4.0

**Release date:** 2020-11-26

This is the fourth MINOR prerelease, adding support for suspension
of resources using `.spec.suspend`, and watchers for the upstream
sources of `HelmChart` resources to detect revision changes faster.

## 0.3.0

**Release date:** 2020-11-19

This prerelease comes with a fix to garbage collection.
The status sub-resource has a new field called `LastHandledReconcileAt`
that can be used to track the reconciliation progress.

This version comes with a breaking change to the API package:
the status condition type is imported from Kubernetes API machinery 1.19.

## 0.2.2

**Release date:** 2020-11-12

This prerelease comes with improvements to status reporting.
The Kubernetes packages have been updated to v1.19.

## 0.2.1

**Release date:** 2020-10-30

This prerelease comes with a fix for a regression bug (introduced in
`v0.2.0`) where dependency entries in the `Chart.yaml` file during the
(re)packaging of the Helm chart artifact would have their names
overwritten with the alias if defined.

## 0.2.0

**Release date:** 2020-10-29

This is the second MINOR prerelease, it comes with breaking changes:

* Due to a change of semver library to exclude pre-releases from `1.0.x`
  ranges, support for more complex ranges like
  `>=1.0.0 <2.0.0 || >=3.0.0 !3.0.1-beta.1` has been dropped.
* The histogram metric `gotk_reconcile_duration` was renamed to `gotk_reconcile_duration_seconds`

Other notable changes:

* Ambiguous semver matches are now sorted by the timestamp of the source
  system to use the most recent match.
* Added support for downloading dependencies for Helm charts from
  `GitRepository` and `Bucket` sources.
* Added support for creating artifacts for packaged Helm charts (`.tgz`)
  from `GitRepository` and `Bucket` sources.
* The annotation `fluxcd.io/reconcileAt` was renamed to `reconcile.fluxcd.io/requestedAt`,
  the former will be removed in a next release but is backwards
  compatible for now.

## 0.1.1

**Release date:** 2020-10-13

This prerelease comes with Prometheus instrumentation for the controller's resources.

For each kind, the controller exposes a gauge metric to track the `Ready` condition status,
and a histogram with the reconciliation duration in seconds:

* `gotk_reconcile_condition{kind, name, namespace, status, type="Ready"}`
* `gotk_reconcile_duration{kind, name, namespace}`

## 0.1.0

**Release date:** 2020-09-30

This is the first MINOR prerelease, it promotes the
`source.toolkit.fluxcd.io` API to `v1beta1` and removes support for
`v1alpha1`.

Going forward, changes to the API will be accompanied by a conversion
mechanism. With this release the API becomes more stable, but while in
beta phase there are no guarantees about backwards compatibility
between beta releases.

## 0.0.13

**Release date:** 2020-09-01

This prerelease fixes a bug in the packaging of `HelmChart` artifacts
build from `GitRepository` sources, and improves the logic of the
`Storage.ArtifactExist` method to not follow symlinks and only return
`true` for regular files.

## 0.0.12

**Release date:** 2020-08-31

This prerelease adds support for `HelmChart` artifacts build from
`GitRepository` sources, and includes several (breaking) changes
to the API:

* The `Name` field in the `HelmChartSpec` has been renamed to `Chart`,
  and may now contain the path a chart is available at in a referred
  Source.
* The `HelmRepositoryRef` field in the `HelmChartSpec` has been renamed
  to `SourceRef`, and may now contain a reference to `HelmRepository`
  and `GitRepository` resources.
* The `Kind` field in the `SourceRef` object is now mandatory.

Other notable changes: the `HelmChart` `Version` field now supports the
same ranges as the `GitRepository` SemVer checkout strategy, support for
relative URLs in `HelmRepository` indexes, and several other bug fixes.

## 0.0.1-alpha.3

**Release date:** 2020-04-27

This alpha release contains a [bug fix](https://github.com/fluxcd/source-controller/pull/42)
for `GitRepositories` status reporting and allows
[waiting for sources on-demand sync](https://github.com/fluxcd/source-controller/pull/43).

## 0.0.1-alpha.2

**Release date:** 2020-04-24

This is the second alpha release of source controller.

It introduces a timeout field to the [`GitRepositoriesSpec`](docs/spec/v1alpha1/gitrepositories.md)
and [`SyncAt` annotation to the common spec](docs/spec/v1alpha1/common.md#source-synchronization).
Furthermore, it allows configuring the amount of concurrent reconciliation
operations per reconciler using the newly introduced `--concurrent` flag
(defaults to `2`), and introduces a `--log-json` flag to enable JSON logging.

Liveness and readiness probes have been added to the deployment manifest, and
the security has been strengthened by running the controller as a non-root user
by default and adding a container security context. 

Tests have been added to ensure correct behaviour of the `HelmChartReconciler`
and `HelmRepositoryReconciler`.

## 0.0.1-alpha.1

**Release date:** 2020-04-16

This is the first alpha release of source controller.
The controller is an implementation of the
[source.fluxcd.io/v1alpha1](https://github.com/fluxcd/source-controller/tree/v0.0.1-alpha.1/docs/spec/v1alpha1) API
based on the specifications described in the
[Source Controller Proposal](https://github.com/fluxcd/source-controller/tree/v0.0.1-alpha.1/docs/spec).
