LTS version

Definition

An LTS version, or Long-Term Support version, is a specific release of software that is maintained and supported for an extended period. This type of version is particularly important for users who require stability and reliability in their applications. LTS versions receive regular updates, including security patches and bug fixes, but do not typically include new features that could disrupt the existing functionality. This approach allows developers and organisations to plan their deployments with confidence, knowing they are using a version that will be supported for a defined timeframe.

Why it matters

LTS versions are crucial for businesses and developers who prioritise stability over the latest features. By using an LTS version, teams can avoid the risks associated with frequent updates that might introduce breaking changes or bugs. This is especially important in production environments where downtime or errors can lead to significant financial losses. Additionally, LTS versions often provide a predictable upgrade path, allowing teams to plan their development cycles and resource allocation more effectively.

Example in VCA

In the Vibe Code Academy, when working on projects that involve frameworks like Node.js or React, students are often encouraged to use the LTS versions of these technologies. For instance, if a student is developing a web application using Node.js, they would select the latest LTS version to ensure they benefit from the latest security updates while maintaining a stable development environment. This practice helps students learn to build applications that are robust and reliable, preparing them for real-world scenarios.

Another Real World Example

Consider a company that develops a financial application. They choose to build their software using the LTS version of a database management system like MySQL. By doing so, they ensure that their application remains stable and secure over time, as they receive critical updates without the need to frequently adapt to new features. This decision allows the company to focus on building functionality rather than dealing with the potential disruptions caused by non-LTS versions.

Common mistakes

Many developers mistakenly assume that using the latest version of a software tool is always the best choice, ignoring the benefits of LTS versions.
Some teams fail to check the support timelines for their software, leading to unexpected end-of-life issues when using non-LTS versions.
A common error is neglecting to update to the latest LTS version when it becomes available, leaving applications vulnerable to security risks.
Developers sometimes mix LTS and non-LTS versions in the same project, which can lead to compatibility issues and unexpected behaviour.
Lastly, relying on LTS versions without understanding their specific support policies can result in confusion about when to plan for upgrades.
