March 2026 monthly wrap-up focused on delivering tighter thermostat control and improving user guidance across core and docs. Key improvements include runtime constraints and cooldown enhancements for Generic Thermostat, plus explicit config-flow validation messaging to reduce misconfigurations. Documentation now covers new cycle controls and clarifies time-setting requirements to speed onboarding and reduce support overhead. The coordinated changes across core and documentation improve energy efficiency, reliability, and overall user satisfaction.

March 2025: Stability focus for thermostat control in home-assistant/core. Implemented a critical Thermostat Activation Range Guard bug fix, enhanced temperature handling logic, and added zero-tolerance tests.
