In this section, we are going to highlight the most important changes and features introduced in PlatformIO Core 5.0. Please visit PlatformIO 5.0.0 Release Notes for more detailed information.
PlatformIO Trusted Registry
PlatformIO Core 5.0 has been switched to the official PlatformIO Trusted Registry :
- Enterprise-grade package storage with high availability (multi replicas)
- Secure, fast, and reliable global content delivery network (CDN)
- Universal support for all packages:
- Development platforms
- Built-in fine-grained access control (role-based, teams, organizations).
The new Web front-end and upgraded PlatformIO Home are coming soon.
PlatformIO Core 5.0 is fully unlocked for developers and teams. They can now share their packages (libraries, Development Platforms, toolchains) with team members or collaborate on open source projects. There are new CLI commands that help you to manage organizations, teams, team memberships, and resource access:
- platformio package – manage packages in the registry
- platformio org - manage organizations
- platformio team - manage teams and team memberships
- platformio access – manage package access for users, teams, and maintainers.
The package management infrastructure has been rewritten from scratch. It is based now on the new PlatformIO Trusted Registry that supports a strict dependency declaration using the package owner. This improvement resolves the issues when package maintainers publish packages under the same name.
PlatformIO Core 5.0 does not handle packages from unofficial repositories declared via
platform.json. There were a lot of security issues and reports when PlatformIO Core 4.0 hangs when you manage external dependencies.
PlatformIO Core 5.0 uses THE ONLY official PlatformIO Trusted Registry that supports not only the libraries but also Development Platforms and toolchains.
Package maintainers can publish their libraries, development platforms, and toolchains to the registry using platformio package CLI.
The biggest improvement for Library Management is the owner-based dependency declaration. You can finally forget about conflicts with library names in the registry. Use the new syntax
ownername/pkgname to declare an owner-based dependency in “platformio.ini” (Project Configuration File) via lib_deps:
[env:myenv] platform = ... framework = ... board = ... lib_deps = bblanchon/ArduinoJson @ ^6.16.1 knolleary/PubSubClient @ ^2.8
You can find an owner name of a library in the registry using PlatformIO Home > Libraries > Some Library > Installation tab.
PlatformIO Core 5.0 build engine has been upgraded to the latest SCons 4.0 - a next-generation software construction tool:
- Configuration files are Python scripts – use the power of a real programming language to solve build problems
- Built-in reliable and automatic dependency analysis
- Improved support for parallel builds
- Ability to share built files in a cache to speed up multiple builds.
- Pre/Post processing based on dependent sources (another target, source file, etc.)
- Command launcher with own arguments
- Launch command with custom options declared in “platformio.ini” (Project Configuration File)
- Python callback as a target (use the power of Python interpreter and PlatformIO Build API)
- List available project targets (including dev-platform specific and custom targets) with a new
platformio run --list-targetscommand
See Build System section in PlatformIO Core 5 release notes for more details.
PlatformIO Core 5.0 is fully backward compatible with PlatformIO 4.0 projects.
See migration guide from 4.x to 5.0 for the further details.
