+## Guidelines for updating this changelog
+
+When making changes to this project, please update the "Unreleased" section with your changes under the appropriate category:
+
+- **Added** for new features.
+- **Changed** for changes in existing functionality.
+- **Deprecated** for soon-to-be removed features.
+- **Removed** for now removed features.

+
+## [0.7.0](https://github.com/quantumkithub/pepskit.jl/compare/v0.6.0...v0.7.0) - 2025-11-17
+
+### Added
+
+- Real time and finite-temperature evolution functionality for simple update
+- Correlator for mixed state `InfinitePEPO`
+- `SUWeight` to `CTMRGEnv` conversion (as `InfinitePEPS` environment)
+- Simple update for PEPO (including 3-site version)
+- Single-layer and double-layer PEPO reduced density matrix
+- `spacetype` method for `InfinitePartitionFunction`
+- Support for `SU2Irrep` symmetry in `j1_j2_model`
+
+### Changed
+
+- A unified interface for Trotter-based time evolution algorithms. The old `su_iter`, `simpleupdate` functions should be replaced by `timestep`, `time_evolve` respectively
+- Default fixed-point gradient algorithm changed to `:eigsolver`
+- BoundaryMPS methods now have their own custom transfer functions, avoiding a double conjugation and twist issues for fermions
+- `physicalspace` and related functions now correctly handle periodic indexing for infinite networks
+- Updated compatibility with TensorKit v0.15
+- Restrict Julia to `<v1.12` due to Zygote incompatibility
+- Runic formatter
+
+### Removed
+
+- `InfiniteWeightPEPS` and `mirror_antidiag`
+- Support for integer space specifiers in state and environment constructors
+- Removed redefinition of `tensorexpr`
+- Support for dual physical spaces for non-bosonic symmetries
+
+### Fixed
+
+- Add unit normalization of the half and full infinite environments before the projector computation, fixing an issue with the gradient accuracy
+- Fix sporadic test timeouts when running variational optimization after simple update for the Heisenberg model by switching to a `GMRES`-based gradient solver
+- Rotation of iPEPO is now done correctly
+- Fix `rotl90`, `rotr90` and `rot180` for `LocalOperator`
+- Fix XXZ model convention
+- Fix `add_physical_charge` for fermionic operators
+- Fix `maxiter` behavior for fallback gradient linear solver
+- Fix gauge fixing in `:fixed` mode for non-uniform unit cells from full SVD
+
+
+### Performance
+
+- Avoid `@autoopt` for partition function calculations
+- Multithreaded scheduler now correctly taken into account for the reverse rules.
