The package uses ArrayInterface.qr_instance (line 268 in src/FastAlmostBandedMatrices.jl), which was not available in ArrayInterface 7.0-7.4. Testing shows that ArrayInterface 7.5 is the minimum version that provides this function. Updated the compat entry from "7" to "7.5" to reflect the actual minimum requirement. Verified by testing with minimum versions - tests pass with ArrayInterface 7.5 but fail with ArrayInterface 7.0-7.4 due to UndefVarError for qr_instance. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

ArrayInterface.qr_instanceat line 268 insrc/FastAlmostBandedMatrices.jl, but this function was not available in ArrayInterface versions 7.0-7.4. This causes the package to fail to precompile when users have older versions of ArrayInterface installed within the stated compatibility bounds.Solution
Updated the compat entry in
Project.tomlfromArrayInterface = "7"toArrayInterface = "7.5"to reflect the actual minimum requirement.Testing
