As we forecast in previous announcements, we have released ITensors.jl v0.7. This is a major breaking release because it removes all of the MPS/MPO functionality from ITensors.jl and moves it to ITensorMPS.jl as part of the new ITensorMPS.jl v0.3 release. Additionally, all of the code from ITensorTDVP.jl has been moved to ITensorMPS.jl, and ITensorTDVP.jl will be deprecated.
See the News section of the ITensors.jl documentation for more details. Please start a new post on this forum or raise an issue on Github if you have any issues.
