Breaking Changes

⚠️ feature #105 is a breaking change, the repartition will work as expected BUT you may have some changes for specific users. A user who was affected by a flag is not guaranteed to still be affected.

This breaking change is needed to unblock future features like #101.

We accept this breaking change only because we are still in version v0.X, as soon as we hit the v1.X this kind of change will not be possible.

Features

• #106 - Add webhook data exporter
• #109 - Add experimentation capability with the possibility to configure a startDate and an endDate for the flag.
• #105 - Accept a more fine-grained percentage, the hash is now compute with a 100000 range when it was 100 before.

Changes

• #108 - PayloadURL is deprecated and you should use EndpointURL instead.

v0.11.0

v0.11.0

Features

• #94 - Add a log data exporter to replace automatic variation logging
  ⚠️ Breaking changes
  If you were using these logs, you need to add the log data exporter to your configuration.

err := Init(Config{
	// ...
	DataExporter: DataExporter{
		Exporter: &ffexporter.Log{},
	},
})

Migration

If you were using Webhooks before, you should have a configuration like this:

ffclient.Init(ffclient.Config{ 
    Retriever:      &ffclient.FileRetriever{Path: "testdata/flag-config.yaml"},
    FileFormat:     "yaml",
    Webhooks:       []ffclient.WebhookConfig{
        {
            PayloadURL: " https://example.com/hook",
            Secret:     "Secret",
            Meta: map[string]string{
                "app.name": "my app",
            },
        },
    },
}

With Notifiers, your configuration should looks like this now:

ffclient.Init(ffclient.Config{ 
    Retriever:      &ffclient.FileRetriever{Path: "testdata/flag-config.yaml"},
    FileFormat:     "yaml",
    Notifiers: []ffclient.NotifierConfig{
        &ffclient.WebhookConfig{
            PayloadURL: " https://example.com/hook",
            Secret:     "Secret",
            Meta: map[string]string{
                "app.name": "my app",
            },
        },
    },
}
