Key Firmware Updates and History
Version 5.5.140 (August 2025): Released to address issues with reticle visibility, restoring them to previous, more visible, levels after a prior update made them harder to see.
Version 5.5.110 (Late 2024/Early 2025): Introduced significant changes including a revised ballistic calculator, improved LRF display, and new color options for the screen and reticle.
Interim Fix/Updates (Mid 2025): Addressed issues with holding zero and reticle visibility, allowing users to revert to more functional settings if the 5.5.110 update caused issues with, for example, the "stepped" zoom feature.
Original Alpex Updates (Nov 2022/Early 2023): Early updates for the original Alpex (non-4K) introduced "Smart IR" (on/off) and updated profile names to "zeroing profiles".

Known Issues and Background
Reticle/Zeroing Issues: Some users reported that certain updates caused issues with maintaining zero or made the reticle harder to see, which was subsequently addressed by "interim" updates in 2025.
Zoom Functionality: The update to 5.5.110 changed the zoom from "stepped" to "gradual," but later feedback suggested a return to the more preferred stepped zoom.
LRF Display: The 5.5.110 update modified the LRF display to be integrated into the reticle area, which some users found less desirable than previous layouts.
