🔧 Meshtastic Firmware v2.7.23.b246bcd — Meshtastic Firmware 2.7.23.b246bcd Alpha

A new Meshtastic firmware pre-release is out: v2.7.23.b246bcd (Meshtastic Firmware 2.7.23.b246bcd Alpha).

This is the first new firmware release in several weeks, so it’s worth a look for Oklahoma mesh operators who like to stay close to upstream changes before the next stable lands.

What stands out

• Fixes a heap blowout issue on T-Beam hardware.
• Improves Linux input handling and several native/meshtasticd maintenance items.
• Continues cleanup and dependency refresh work across the build system and device UI stack.

Why Oklahoma operators may care

• If you’re testing portable or fixed nodes on older T-Beam gear, the memory fix may matter.
• This is still an alpha/pre-release, so production backbone or high-importance relay nodes should probably wait unless you need a specific fix.
• Good candidate for lab nodes, travel kits, and secondary routers before wider rollout.

Release notes summary

• Native semaphore synchronization fix.
• New meshtasticd configs for additional mPWRD-OS targets.
• Linux input enable-logic fix.
• SFTP-based PPA upload changes and build/dependency maintenance.
• Several dependency bumps including GxEPD2 and LovyanGFX.

Note: This is a pre-release. Flash test nodes first, back up configs, and don’t shotgun it onto critical infrastructure unless you enjoy self-inflicted chaos.
