what is freertos-lts fr?

FreeRTOS LTS gives companies a stable, long-lasting version of the software that powers small connected devices. When you ship a physical product like a smart thermostat or a factory sensor, you need its internal software to keep working without constantly rewriting it. This project bundles the core operating system for embedded devices along with a collection of networking and security tools, then promises to maintain that bundle with security patches and bug fixes for two years. AWS maintains these releases to help reduce the cost and effort of keeping already-deployed products secure and up to date. The project is essentially a curated package of specific, pinned versions of individual libraries. Rather than tracking the latest changes across dozens of separate projects, a hardware team can grab this one bundle and know everything inside it is tested and compatible. The bundle includes the core system that schedules tasks on a microcontroller, plus tools for common connectivity needs: messaging protocols to talk to the cloud, HTTP clients, JSON parsers, and libraries for securely connecting to AWS IoT services. If a critical security flaw is found, the maintainers release a patch for this specific bundle rather than forcing you to upgrade to a brand new, potentially incompatible version. This matters most for teams building connected hardware that needs to last years in the field. Imagine you make smart locks for apartment buildings or cellular-connected delivery trackers. Once those devices are out in the world, pulling them back to flash new firmware is expensive and risky. With this long-term support release, you get a predictable foundation that stays stable until 2028. AWS also offers an extended plan that can stretch support up to ten additional years for devices with especially long lifecycles. One notable tradeoff: the project prioritizes predictability over new features. You will not get the cutting-edge capabilities of the latest development branches, but you will not get surprise breaking changes either. A few libraries did receive major version bumps in this release, and the project provides migration guides for those specific cases. For most of the bundle, though, upgrading from a previous long-term release should be straightforward.
