Here are the April updates for developers, AI enthusiasts, and content creators!
The release of WordPress 6.8 “Cecil” brings major improvements in performance, design, and security — enhancing both traditional and block-based editing experiences.
At the same time, Google introduced Firebase Studio, a new cloud platform for fast, no-code AI app prototyping and deployment. NativePHP empowers PHP developers to create native mobile and desktop apps without switching to new languages.
Finally, OpenAI expanded its model lineup, offering the versatile GPT-4o alongside specialized lightweight models, giving developers more options for innovation.

WordPress 6.8 "Cecil": Better Performance, Design, and Security
Mikuláš Žačok
Visual Content Creator
WordPress continues its tradition of developing the block editor and adds small but practical features. These include, for example, Query Total, which displays the number of displayed items, and an improved Query Loop, which now allows you to ignore “sticky” posts. A Lightbox feature has been added to the gallery, allowing images to be enlarged by clicking on them, similar to how it works with single images.
In terms of styling, there are new features like a reset button — a quick way to restore default color, shadow, and duotone settings in global styles. The Style Book is now available for classic themes as well, expanding design possibilities.
For me, the most important part — since I don’t use the block editor — is the improvement in performance and security. The key new features are:
- Speculative Loading: Preloading links before clicking them, speeding up page loading times.
- Interactivity API: Introduction of asynchronous processing of interactions, reducing delays and improving page responsiveness.
- Password security using bcrypt: Instead of the older phpass algorithm, the more secure bcrypt is now used, significantly improving the protection of user accounts

Firebase Studio – Rapid AI App Building with Gemini
Gabriel Falis
Developer
Google has introduced Firebase Studio — a new cloud development environment that enables rapid design, prototyping, and deployment of fully functional AI applications directly in the browser. Thanks to Gemini AI integration, you can create UIs, API schemas, and AI flows using natural language, images, or drawings without needing to write any code.
Main benefits of Firebase Studio:
- Rapid app prototyping with an AI assistant – Simply describe an idea, upload an image or sketch, and Firebase Studio will generate a functional prototype.
- Always-available AI support from Gemini – Code generation, debugging, testing, and documentation directly within the environment.
- Easy deployment and sharing – With a single click, deploy your app to Firebase App Hosting and immediately test or share it via URL or QR code.
- Flexibility – Import your own projects, use familiar frameworks, and customize the development environment to your team’s needs.
What would I appreciate most as a developer?
The biggest advantage for me is the constant AI support directly within the environment. Being able to generate code, fix bugs, write tests, and create documentation with Gemini’s assistance — without switching tools — greatly accelerates development and saves time.
Firebase Studio thus significantly speeds up AI app development, reduces technical complexity, and allows developers to focus on innovation rather than routine tasks.

NativePHP v1: Building Native Apps Using PHP
Lukáš Huňár
Developer
What if you could build real iOS and Android apps using your existing Laravel skills?
No Swift. No Kotlin. No Flutter. No React Native. Just Laravel.
This dream is about to become reality.
NativePHP is a new framework for quickly creating rich, native desktop and mobile applications using PHP. If you’re already a PHP developer, you’ll feel right at home with NativePHP. If you’re new to PHP, you’ll find working with NativePHP simple and intuitive.
NativePHP combines:
- A collection of easy-to-use classes that interact with various operating system functions.
- A toolkit for building and packaging your native app.
- A static PHP runtime environment that allows your app to run on the user’s device without additional setup.
NativePHP features include:
- Window management
- Menu management
- File management
- Database support (SQLite)
- Native notifications
- …and more.

New OpenAI Model Offerings

Developer
Adapted from a great post by user @Andr3jH z platformy X
GPT-4o
- The current “go-to” model for everyday uses.
- Fast, smart, and now capable of generating images at unprecedented quality.
o3
- The highest-performing reasoning model, recently made available to paying customers.
- Handles the toughest tasks — but has longer response times and high costs.
o4-mini, o4-mini-high
- Not the flagship like o3 but offers comparable performance for a fraction of the cost and reasonable speed.
- The “-high” version takes a bit longer to respond for better results.
GPT-4.5
- Although it lags behind its siblings in some areas, it excels in emotional intelligence, natural writing, and creativity.
- Answers feel much less robotic, almost as if the model “thinks on its own.”
- Expensive and available only until July 14, 2025 — hopefully a worthy successor will arrive by then.
GPT-4.1, GPT-4.1-mini, GPT-4.1-nano
- Available only through API access.
- GPT-4.1 aimed to compete with Claude Sonnet and Gemini in code generation — but early feedback is mixed.
- Smaller variants offer almost instant responses and very low costs, making LLM integration into regular apps more accessible than ever.
What does the letter “o” stand for?
In GPT-4o, it stands for “omni” — meaning versatile (handling text, images, and sound). For o3 and o4-mini, the meaning is less clear, but it’s commonly believed to simply abbreviate OpenAI.
Maybe someday OpenAI will introduce models with more intuitive names. Until then, keep following Coder’s Corner!
