-- February 3, 2025: ITensors.jl v0.8 has been released. This release should not be breaking to the average user using documented features of the library. This removes internal submodules that held experimental code for rewriting the internals of NDTensors.jl/ITensors.jl, which have now been turned into separate packages for future development. It is marked as breaking since ITensorMPS.jl was making use of some that experimental code, and will be updated accordingly.
+- February 3, 2025: ITensors.jl v0.8 has been released. This release should not be breaking to the average user using documented features of the library. This removes internal submodules that held experimental code for rewriting the internals of NDTensors.jl/ITensors.jl, which have now been turned into separate packages for future development. It is marked as breaking since ITensorMPS.jl was making use of some of that experimental code, and will be updated accordingly. Also note that it fixes an issue that existed in some more recent versions of NDTensors.jl v0.3/ITensors.jl v0.7 where loading ITensors.jl in combination with some packages like LinearMaps.jl caused very long load/compile times (https://itensor.discourse.group/t/linearmaps-and-itensors-incompatibility/2216), so if you are seeing that issue when using ITensors.jl v0.7 you should upgrade to this version.
 
 - October 25, 2024: ITensors.jl v0.7 has been released. This is a major breaking change, since all of the MPS/MPO functionality from this package has been moved to [ITensorMPS.jl](https://github.com/ITensor/ITensorMPS.jl), along with all of the functionality of [ITensorTDVP.jl](https://github.com/ITensor/ITensorTDVP.jl). If you want to use MPS/MPO types and related functionality, such as `MPS`, `MPO`, `dmrg`, `siteinds`, `OpSum`, `op`, etc. you now must install and load the ITensorMPS.jl package. Additionally, if you are using ITensorTDVP.jl in your code, please change `using ITensorTDVP` to `using ITensorMPS`. ITensorMPS.jl has all of the same functionality as ITensorTDVP.jl, and ITensorTDVP.jl will be deprecated in favor of ITensorMPS.jl. **Note:** If you are using `ITensors.compile`, you must now install and load the ITensorMPS.jl package in order to trigger it to load properly, since it relies on running MPS/MPO functionality as example code for Julia to compile.
