When will the TP-Link Archer C50v6 version be supported?

May I ask when will the TP-Link Archer C50v6 version be supported? I downloaded the OpenWrt firmware, but found that it does not seem to be the latest firmware version. I am very sorry that I am a beginner.

I downloaded firmware OpenWrt Install file from this page:https://firmware-selector.openwrt.org/?version=23.05.0-rc2&target=ramips%2Fmt76x8&id=tplink_archer-c50-v4 .
But installation was interrupted without effect.

Sincerely!

Officially, probably never.

v4 stands for the version if the router, not Openwrt.
