Release notes

Fix RF address aliasing. RECEIVER_BASE is now arithmetically added to NODE_ID instead of OR'd. Pre-v10 receivers with even NODE_IDs already used BASE+N by accident (because OR with 0x01 == +1 when LSB=0), so they don't move; receivers with odd NODE_IDs shift up by one address slot. Pair only with dongle FW v8+.

Upgrade notes

• Coordinated upgrade: bump the dongle to FW v8+ at the same time, or odd-NODE_ID receivers will be deaf.
• Operationally most fleets only have a handful of odd-NODE_ID units; identifying them is straightforward (see also v16 for at-a-glance NODE_ID boot LEDs).

How to flash

• Wired only. Flashing a receiver.
