What Is a Software Release? | phoenixNAP IT Glossary

A software release refers to the distribution of a new or updated version of a software product.

What Do You Mean by Software Release?

A software release is the process of making a new or updated version of a software product available to users. It involves preparing the software, testing its functionality, and then distributing it to users or customers through various channels. A release can include various types of changes, such as the introduction of new features, the correction of existing bugs, improvements in performance, and updates aimed at enhancing security.

Software releases may be versioned to distinguish different stages of development, with major releases often representing significant updates or overhauls, while minor updates or patches address smaller issues or add incremental improvements. The release process is crucial in ensuring that the software functions properly, remains secure, and meets the evolving needs of its users.

Software Release Types

Software releases can be categorized into several types based on their purpose, scale, and stage in the development lifecycle. Below are the common types of software releases.

Alpha Release

The alpha release is an early version of the software that is often incomplete and intended for internal testing within the development team or by selected users. It includes basic features but may still contain numerous bugs. The main goal of an alpha release is to test the core functionality of the software in a controlled environment before further development and refinement.

Beta Release

A beta release is a more refined version of the software than the alpha release and is made available to a wider audience, often external testers or early adopters. While most of the features are present, the software may still have bugs and issues that need to be addressed. The beta phase is intended to gather feedback, identify problems in real-world usage, and make improvements before the final release.

Release Candidate (RC)

A release candidate is a version of the software that is close to the final release and is considered stable enough for wider testing. The main difference between an RC and a beta release is that a release candidate is feature-complete and mainly focuses on bug fixes, security patches, and final adjustments. If no major issues are found during testing, the release candidate may become the final version.

Stable Release

A stable release is the final version of the software that has passed all the testing phases, including alpha, beta, and release candidates. This version is considered ready for general use by all users and typically focuses on delivering a reliable, fully functional product. Stable releases may be incremented over time through minor updates and patches.

Patch Release

A patch release typically addresses specific issues that have been discovered after the stable release. It is usually a smaller update aimed at fixing bugs, security vulnerabilities, or performance issues without introducing new features. Patch releases are often numbered incrementally, such as "1.0.1" or "2.3.4," and are intended to maintain the stability and security of the software.

Major Release

A major release introduces significant changes to the software, such as new features, a complete overhaul of the existing system, or enhancements that significantly change the user experience. Major releases often include backward-incompatible changes, which may require users to adapt or update their existing systems. These releases are typically denoted by a change in the first number of the version (e.g., from version 1.x to version 2.x).

Minor Release

A minor release typically includes smaller feature updates, improvements, or new features that do not drastically alter the software. These releases focus on enhancing functionality while maintaining compatibility with previous versions. Minor releases are usually indicated by a change in the second number of the version (e.g., from version 1.0 to version 1.1).

Hotfix Release

A hotfix release is a quick fix deployed to resolve critical issues, such as severe bugs or security vulnerabilities, that need immediate attention. Hotfixes are often released outside of the regular release cycle to ensure that users are protected from pressing issues. These releases tend to be small and specific, addressing one or a few problems without introducing new features.

Software Release Stages

Software release stages refer to the distinct phases that a software product goes through before being made available to users. Each stage serves a specific purpose, from initial development to final distribution, ensuring that the software is tested, refined, and ready for use. These stages help developers manage the software lifecycle, minimize bugs, and ensure high-quality releases.

Planning and Requirements Gathering

The first stage of a software release involves planning and gathering requirements. During this phase, the development team works with stakeholders to define the features, functionality, and goals for the software. This stage sets the foundation for all future development by ensuring that there is a clear understanding of what the software should achieve and what resources are necessary for its creation.

Design and Architecture

Once the requirements are gathered, the software’s design and architecture are planned. This includes defining the system structure, technology stack, and overall framework. During this stage, developers plan how the software will be built, ensuring that it can handle the intended functionality and scale. Proper design at this stage is crucial for preventing issues later in the development cycle.

Development

The development stage is where the actual coding of the software happens. Developers write the code, implement the planned features, and create the necessary modules to make the software functional. The development stage is often iterative, with developers working in sprints or cycles to build different parts of the software progressively.

Testing

After the development phase, the software moves to the testing stage. This is where the software undergoes thorough testing to identify bugs, performance issues, and security vulnerabilities. Testing may include unit testing, integration testing, system testing, and user acceptance testing (UAT). The goal is to ensure the software works as intended and is free of critical issues before it reaches users.

Alpha Release

The alpha release is the first version of the software that is shared outside the development team. It is usually an early, unfinished version of the software that may contain many bugs and incomplete features. Alpha releases are primarily for internal testing and to get feedback on the core functionality of the software.

Beta Release

In the beta release stage, the software is made available to a select group of external users or testers. The software is more stable than in the alpha stage, but it still may have some issues. Beta testing helps gather real-world feedback, identify additional bugs, and test how the software performs in different environments and use cases.

Release Candidate (RC)

A release candidate is a version of the software that is feature-complete and ready for final testing. The RC stage focuses on identifying any remaining issues that need to be resolved before the final release. If no major problems are discovered, the release candidate will be promoted to the final stable version of the software.

General Availability (GA)

General Availability (GA) is the stage when the software is released to the public and is considered stable enough for widespread use. It is the first official, fully supported version of the software and is considered ready for production environments. GA releases are usually accompanied by full documentation, support, and deployment resources.

Post-Release (Maintenance and Support)

After the software is released, it enters the post-release phase, where it is maintained and supported. During this stage, developers fix any bugs or issues reported by users, release patches, and provide updates. This phase ensures that the software remains functional, secure, and aligned with user needs over time.

Software Release Methodologies

Software release methodologies are frameworks or approaches that guide how software is developed, tested, and delivered to users. Each methodology has its own set of practices, goals, and processes for managing releases, ensuring that software is delivered in a structured, efficient, and predictable way. Below are some common software release methodologies:

Waterfall. The Waterfall methodology is a linear, sequential approach to software development. In this model, each phase of the software development process (such as requirements gathering, design, development, testing, and deployment) is completed before moving on to the next. Releases typically happen after all stages are completed, and there is minimal flexibility for changes once the process has started.
Agile. Agile is an iterative and incremental methodology where software is developed in small, manageable chunks called "sprints" or "iterations." Each sprint results in a working release that can be reviewed, tested, and improved upon in subsequent iterations. This approach allows for frequent releases, faster feedback, and adaptability to changes during development.
Continuous Integration and Continuous Delivery (CI/CD). CI/CD is a methodology that emphasizes frequent and automated software integration and delivery. With CI, developers regularly integrate code into a shared repository, where automated tests verify the code's functionality. CD ensures that software is automatically deployed to production once it passes the integration and testing stages, allowing for rapid releases with minimal manual intervention.
DevOps. DevOps is a set of practices that combines software development (Dev) and IT operations (Ops). It aims to shorten the development lifecycle by fostering collaboration between development and operations teams. DevOps emphasizes automation, continuous testing, continuous integration, and continuous deployment to deliver software quickly and reliably, with frequent releases.
Feature-driven development (FDD). FDD is a model focused on delivering software based on the completion of specific features. In this methodology, development is organized around designing and building features that provide clear, valuable functionality for the user. Each feature is developed, tested, and released individually, ensuring a steady flow of small, functional updates.
Release train. Release train is a methodology where software releases are scheduled at regular intervals (e.g., monthly or quarterly), rather than being tied to specific feature completion. This approach ensures that software updates are consistently delivered on time, and features are prioritized and planned based on the scheduled release cycles.
Incremental model. The incremental model divides the software into smaller, manageable components or increments, which are developed, tested, and released individually. Each increment adds additional functionality to the software, with the final product being assembled from all the increments. Releases are made after each increment is completed and validated.

Roles in Software Release

The roles in a software release are the key responsibilities and individuals involved in the process of planning, developing, testing, and delivering software to end users. Each role ensures that different aspects of the release process are managed effectively, from development and quality assurance to deployment and support. Below are the primary roles involved in a typical software release:

Product manager. The product manager is responsible for defining the overall vision and goals of the software release. They work with stakeholders to prioritize features, gather requirements, and ensure that the software meets customer and business needs.

Their feedback and experiences with the software during and after the release are invaluable. The end user role can sometimes include participating in beta testing or providing feedback through support channels after the release.

What Is a Software Release Example?

A software release example would be the launch of a new version of an operating system, such as Windows 11. This release would typically involve multiple stages, starting from internal development and testing (alpha and beta stages) to gathering user feedback. Once bugs are resolved and the software is stable, it would be made available to the public as a "General Availability" (GA) version. Following this release, regular updates and patches may be issued to fix any newly discovered issues or vulnerabilities, ensuring the software remains secure and functional for users.

How to Release Software?

Releasing software involves several key steps to ensure a smooth and successful deployment. Here's a brief overview of the process:

Plan and prepare. Define release goals, schedule, and requirements. Ensure all stakeholders are aligned, and determine the features or fixes that will be included in the release.
Development. Developers write and finalize the code for the release, implementing new features, bug fixes, or enhancements as planned.
Testing. Conduct thorough testing (unit tests, integration tests, QA testing) to identify and fix bugs. This includes user acceptance testing to ensure the software meets user needs.

Security and compliance risks. Ensuring that the software is secure and compliant with relevant regulations is critical. Any vulnerabilities or compliance issues that emerge during the release could lead to security risks, legal complications, or reputational damage.
Scalability and performance. Ensuring the software can handle increased user demand and scale effectively can be a challenge. Performance testing needs to be done to ensure the software doesn’t encounter issues as it grows or when more users access it simultaneously.

What Is the Difference Between Software Release and Deployment?

The terms "software release" and "deployment" are closely related but refer to different aspects of the software lifecycle.

A software release is the process of making a new or updated version of software available to users, typically after it has gone through development, testing, and quality assurance. It involves finalizing features, fixing bugs, and making sure the software is ready for distribution.

Deployment, on the other hand, refers to the actual process of installing and configuring the software on production systems or end-user environments. While a release focuses on the software being made available for use, deployment ensures that the software is properly installed, configured, and ready for use in the target environment. Essentially, release is about availability, while deployment is about the installation and setup of the software.
