April 2026 monthly summary focusing on reliability, performance, and data integrity across two repos: evcc-io/evcc and EVerest/everest-core. Key outcomes include: 1) evcc: fixed response body leak on 404 errors and hoisted Europe/Rome timezone loading to package initialization, reducing startup time. 2) Everest-core: corrected drop_transaction_data to reliably drop every second element via backward iteration, and expanded test coverage with scenarios for 6- and 7-element inputs and padded test data to exceed max_message_size, ensuring robust behavior under load. These changes improve uptime, correctness, and developer velocity.

March 2026 monthly summary for EVerest/everest-core: Strengthened reliability and correctness through two critical fixes: nothrow move constraints for fixed_vector to prevent silent UB; and a race-condition fix in EVSE cable check that prevents permanent charger inoperability when unplugged mid-check. These changes improve robustness, safety, and charging reliability, with updated tests and code hygiene.
