The last release of Energia, the fork of the Arduino IDE and SDK for the LaunchPad boards, was numbered 1.8.10E23 and published in December 2019. This project seems to no longer be maintained.
The official tools from Texas Instruments are Code Composer Studio, based on Eclipse with an online variant. Each wired and wireless micro-controller family has its dedicated SDK. However, those tools are far from easy to use and may not appeal to non-professionals.
As a consequence, the LaunchPad platform and BoosterPack extensions turn legacy.
This is really unfortunate: the LaunchPad MSP432 brought RTOS for everyone with the Galaxia library; the sub-1 GHz CC1352 provided an excellent radio with ultra-low-power performance.
