Laravel 6 focuses on improving stability, performance and developer experience, including: longer maintenance and security updates as an LTS release. Optimize underlying components to improve performance, such as improving routing caching. Enhance existing features such as improving Laravel UI to simplify front-end building.

What has been updated in Laravel 6? This question is wonderful because it is not just a simple version upgrade, but more like a meticulous improvement that moistens things silently. Simply put, it does not bring you any earth-shaking new features, but focuses on improving performance, enhancing security, and improving developer experience. It's like an experienced craftsman who doesn't care about how gorgeous the work it makes at once, but pays more attention to the perfection of every detail, and ultimately presents a kind of natural elegance.

Let's dig deeper. First of all, you have to know that Laravel 6 itself is not a "big version" update, it is more of an LTS (Long Term Support) version, which means you will get longer security updates and maintenance. This is crucial for any project, after all, safety is always first.

Secondly, Laravel 6 optimizes some underlying components. Although you don’t see the huge changes on the surface, these improvements can really improve the performance of your application. For example, improvements to routing cache can significantly reduce the time for routing resolution. I have personally experienced it in a large project. After upgrading to Laravel 6, the startup speed is significantly faster, which is very important in production environments.

Furthermore, Laravel 6 integrates new features, but these features are not entirely new concepts, but enhancements and improvements to existing features. For example, improvements to Laravel UI make building front-end interfaces more convenient and fast. In the past, you might have to manually configure various scaffolding tools, but now you only need simple commands to do it, which saves a lot of time and energy and reduces the possibility of errors.

Speaking of this, I have to mention some of my personal opinions about Laravel. The charm of Laravel is that it consistently adheres to elegant code style and clear architectural design. It is not like some frameworks that constantly innovate in order to pursue the so-called "new features", resulting in frequent changes in APIs and making developers run wild. Laravel focuses more on stability and maintainability, which is crucial for long-term projects.

Below, let’s use a small example to experience the improvements of Laravel 6. Suppose we want to create a simple route:

 <code class="php">// Laravel 5.x 之前的路由定義方式，略顯冗余Route::get('/profile', function () { // ... }); // Laravel 6 及以后版本，更簡(jiǎn)潔的路由定義Route::get('/profile', [ProfileController::class, 'show']);</code>

You see, just the improvement of routing definition methods reflects Laravel's emphasis on developer experience.

Of course, no technology is perfect. Laravel 6 also has some shortcomings. For example, for some very complex application scenarios, you may need to have a deeper understanding of its underlying mechanisms to better optimize performance. And, while it provides a lot of auxiliary tools, if you are not familiar with these tools, it can also lead to some unnecessary trouble. Therefore, it is crucial to learn and understand the core principles of Laravel.

All in all, Laravel 6’s update is not a revolutionary change, but a pursuit of excellence in the existing framework. It focuses on stability, performance and developer experience, and is a very good choice for long-term project maintenance and upgrades. Remember, choosing the right tool is more important than pursuing the latest technology. Instead of blindly pursuing new things, it is better to learn and master existing technologies in depth to make your code elegant and efficient.
