LDK v0.2.6 just closed two nasty holes — a splice-related bug that could quietly drain funds and a payment-handling flaw that could stop saved channel state from loading on restart. If you're running a Lightning node on this stack, this isn't optional maintenance, it's a "do it today" situation. Bugs like these are a good reminder that Lightning is still young infrastructure — solid in concept, but the plumbing needs constant checking.
