Changelog

This is a major release. The most significant change is that libCEC no longer depends on p8-platform — threading, time and IO are now implemented directly on the C++ standard library.

Highlights

• Dropped the p8-platform dependency; threading/time/IO reimplemented on std::
• Replaced the Windows build batch files with a Python build orchestrator
• New: configurable adapter autonomous mode (with an interactive am command in cec-client)
• New: configurable device vendor id (libcec_configuration.iDeviceVendorId, cec-client --vendor-id)
• New: enumerate every /dev/cec* node so multi-HDMI boards can select a CEC port by path
• Extensive security hardening: buffer-overflow and bounds fixes across EDID parsing, the C API, and received-frame parsing in every SoC backend

Library / API

• changed: bump to 8.0.0 and gate bAutonomousMode behind CEC_LIB_VERSION_MAJOR >= 8
• added: a per-adapter display name to the adapter descriptor
• added: Panasonic — send user control power on with image view on so Viera still wakes (#511)
• fixed: suppress double taps and split the auto-repeat delay into a configurable iButtonRepeatDelayMs (#326)
• fixed: emit key release when a held key times out (#704)
• fixed: don't announce active source while the TV is off so an AVR isn't woken up (#403)
• fixed: don't power on the TV when the options to power on were disabled
• fixed: serialise CLibCEC::Open against Close, and stop the cec-client reconnect thread racing teardown (#701)
• fixed: reuse the owning client shared_ptr when re-registering, fixing a monitor-mode toggle crash
• fixed: numerous buffer-overflow and bounds fixes in EDID physical-address parsing, the C API string helpers, and OSD name / menu-language handling
• fixed: release the Python callback argument tuple when no callback is registered for the slot (#686)
• fixed: Python strDeviceLanguage accepts 3-char ISO codes; libcec_mute_audio matches C++ MuteAudio() (#663)
• fixed: OnRegister clears baseDevice when the physical address is already resolved (@jwmay2012)

Platform backends

• fixed: bound received-frame parsing across the RPi, TDA995x, Exynos, AOCEC, Linux, IMX and Tegra backends (#719)
• fixed: honour the connect timeout in the SoC backends instead of ignoring it
• fixed: Linux CEC backend detects node removal and reconnects (#668)
• fixed: RPi — drop TV service and CEC callbacks that race connection teardown (#184, #476)
• fixed: RPi — only enable the backend when all VideoCore libs are found; don't call bcm_host_init() on a non-Pi (#572, #625, #626)
• fixed: RPi — report user control release on button release (@albertvaka, #717)
• fixed: Tegra — track the open state and break the frame on a failed read instead of parsing stale data (#719)
• fixed: initialise cec_adapter_descriptor when detecting adapters (@FabianWolter)

Build

• changed: enable -Wall -Wextra for every target, not just libCEC itself (#715)
• changed: use cmake's GNUInstallDirs instead of a copy of UseMultiArch.cmake
• added: DISABLE_CLIENT, DISABLE_BUILDINFO and DISABLE_STATIC cmake build options
• added: install a CMake package config and keep the library install at LIB_DESTINATION
• removed: the msvc stdint.h shim, which nothing resolves against
• fixed: gcc-16 -Wstringop-truncation and -Wformat-truncation warnings (#715)
• fixed: don't probe the build host for libdir/python layout when cross-compiling (#387, #530)

cec-client

• added: configurable device vendor id via --vendor-id (@Andy1210, #714)
• added: -c/--command and -H/--help-command options (@nelfin)
• changed: document all command line options in --help; exit on stdin EOF instead of spinning

cec-tray / .NET

• added: away-mode support, a working sleep button mapping, and power on the TV when the PC is no longer idle
• fixed: device type selection persists and no longer shows a spurious 'device type changed' dialog (#523, #620, #671, #698)
• fixed: crashes on Kodi start, on resume from standby, and when saving a cleared button mapping
