+### Current known Issues
+* BETA_SETTING: PAL60 when using HDMI mods has regressed (awaiting libdragon fix).
+* The RTC UI requires improvement (awaiting UI developer).
+* Menu sound FX may not work properly when a 64 Disk Drive is also attached (work around: turn sound FX off).
+* ALPHA_FEATURE: ED64 X Series detection does not occur properly (however this is not a problem as not tag released asset).
+* ALPHA_FEATURE: ED64 V Series only supports loading ROMs (however this is not a problem as not tag released asset).
+
+### Breaking changes
+* Disk drive expansion ROMs are now loaded with `Z|L` instead of `R` to align with ROM info context menu (and future functionality).
