@cocoa-xu with OTP26 and elixir 1.15 coming out, do I just need to add them to the precompilation matrix here

exqlite/.github/workflows/precompile.yml

Lines 22 to 23 in 65ac95b

	elixir: ["1.14"]
	otp: ["25", "23"]

Changing it to

        elixir: ["1.14", "1.15]
        otp: ["26", "25", "23"]

Yea that should do it! (Although OTP 26 seemed to be not available on homebrew when I checked it last week.)

Okay. I'll open another PR for the precompilation support for OTP26 and keep an eye on homebrew for an update.
