⌃ [a98d9a8b] Interpolations v0.14.7
Info Packages marked with ⌃ have new versions available and may be upgradable.

julia> itp0 = interpolate([1,2,3,4], BSpline(Linear()))
4-element interpolate(::Vector{Float64}, BSpline(Linear())) with element type Float64:
 1.0
 2.0
 3.0
 4.0

I cannot reproduce the problem on v0.14.7.

Hmm, that's strange. Maybe it's because I'm running on Julia v1.10.0-rc2?
