Feature flags are a great way to control the release of new features in your software. They allow you to easily turn new features on or off without redeploying your code.

However, when implementing a feature flag in an application, we may want to customize its management after the initial release, i.e., schedule an incremental release/delivery strategy that is carried out automatically or schedule future changes to a flag's targeting rule that can take effect at specific time intervals.

For example:

• Activate a flag’s config by date and time. For instance, release a feature at noon on a Sunday afternoon.
• Gradually increase the discount value of an ongoing promotion at specific times of weekdays.
• Enable a feature only on weekends or on weekdays.
• Three days from today, turn on a feature for internal testing and enable it for public use a week later.

The world population continues to grow, and so does the number of house pets. While we all hope most of them have a good quality of life, some don't have a home. To combat this, we can make an animal care app. In this blog post, the app's objective is to increase the pet adoption rate. We will change the color of our call-to-action button and measure the click-through rate of each button version using A/B testing.

The goal of software development workflows is geared toward releasing new features and updates, which can sometimes cause issues if not handled correctly. In my opinion, using feature flags has proven to be essential in situations like these. You can use them to easily deploy new features, and if there are bugs you can quickly turn a feature off, then turned it on again when they have been fixed without having to redeploy the app.

Autumn of 2021 saw the release of the newest .NET version, .NET6. This new release brought some updates that could potentially make a developer’s life easier, such as improved performance and a simpler development process. With less code to write and productivity tools like hot reloading, the new .NET was quickly adopted by developers all over the world.

Even before the new release, .NET had a wide range of utilities and has risen to become of the most popular frameworks available. Whether you’re migrating from an older version or just getting started on a new project, you may be wondering what feature management solutions are available to you. I wondered as well, so in this tutorial, I’ll go over one of the best - using feature flags.

If you’ve been reading about feature flags then I’m sure you’re convinced of the power and value they provide. Since development is mostly a team effort, you may be wondering how to manage a feature flag within a team, regardless of size, so one developer’s work doesn’t affect another’s. Well, in this article, we discuss exactly this issue and offer two solutions, depending on the size of your team.

Picture this: You’ve added a new feature to your software, linked it to a feature flag, and deployed it to production. Now, you’d like to enable this feature for a subset of your users to get their feedback before you take the leap and roll it out to everyone.

But who gets to see this new feature first? How do you choose the first user segment? How do you use feature flag rules to target them?

Good to know: Feature flags let you launch new features and change your software configuration without (re)deploying code.

Let’s look at some typical real-world examples of how you can do canary releases using ConfigCat.

When it comes to smooth deployment and roll-out of new features in software products, feature flags play a critical role. Across software development workflows like agile, they are becoming essential. I have found that using them drastically reduced the risk of adversely affecting user experience since they enable me to quickly disable a new feature if unintentional bugs are discovered.

Knowing up front whether a new feature will improve or worsen user experience can be a challenging decision. If we don't adopt the proper mechanisms and processes to test new features we stand a high risk of introducing new bugs. By incorporating A/B testing into our feature release workflow, we can minimize these situations by testing the new feature with a small sample of users before deploying it.

Java is one of the most widely used programming languages. Whether you've used it, know someone who has, studied it in university, or despise it, it's no surprise that many software products are developed in Java. So, keep reading if you want to learn how to quickly enable features in Java, with no redeployment and no fuss.

We're proudly announcing our 16th SDK release! ConfigCat's C++ SDK is now generally available. This SDK is a native C++ implementation of ConfigCat's feature flag management service. It is designed to be lightweight, easy to use, and easy to integrate into your C++ projects.
