Hi @ValaLin,
As Far As I Know,
There Is No Exact Date On When The Next Firmware Update (v2.4.0) Might Be Released,
But Maybe The Update Might Release In Mid September Of 2023 As The Firmware v2.3.0 Was Released A Few Weeks Ago On July-15-2023 With Language Support Being The Only Features In That Update
I Will Also Tag Moderator @edward So That He Can Help.
