Compatibility, packaging, and release notes Firmware packaging matters: is the update a single monolithic image, or a set of component binaries (bootloader, radio stack, application)? Does the demo package include a flasher utility, an over-the-air payload, or just raw images? Release notes should be explicit about required hardware revisions, preconditions (battery state, peripheral attachments), and behavioral changes that testers should expect. A terse filename like "alps_8227l-demo_firmware_vX.bin" is only useful when matched by comprehensive documentation: changelog entries, supported configurations, and known issues. For hardware integrators, a compatibility matrix that maps board-revision, PCB assembly versions, and radio/regulatory variants to firmware builds prevents costly mistakes.
