+# Release 0.13.0-dev
+
+### New features since last release
+
+### Improvements
+
+### Bug fixes
+
+### Documentation
+
+### Contributors
+
+This release contains contributions from (in alphabetical order):
+
+---
+
+# Release 0.12.0
+
+* Version bump
+
+---
+
+# Release 0.11.0
+
+### New features
+
+* Forest devices now support custom wire labels. #55 #57 #58 #59
+
+  One can now specify any string or number as a custom wire label, and use these labels to address subsystems on the device:
+
+  ```python
+  dev = qml.device('forest.qvm' device='4q-qvm', wires=['q1', 'ancilla', 0, 1])
+
+  @qml.qnode(dev)
+  def circuit():
+     qml.Hadamard(wires='q1')
+     qml.CNOT(wires=[1, 'ancilla'])
+     return qml.expval(qml.PauliZ(0))
+  ```
+
+### Bug fixes
+
+* Fixes a bug where basis states were not correctly initialized #56
+
+* Tensor measurements have been fixed due to a change in PL v0.11 #52
+
+* The QCS no longer supports lattice-based devices such as Aspen-4-5Q-E. As a result, the `forest.qvm` and `forest.qpu` devices no longer accept lattice-based devices, and must be loaded with the full device name (e.g. Aspen-4). #51

+
+# Release 0.9.0
+
+* Adding support for multi-qubit observable estimation.
+
+* Added a new method `analytic_probability()` to the `Wavefunction` simulator devices, so that analytic and non-analytic probabilities are correctly returned.
+
+* Reduced the default number of shots for the `QPUDevice` to 1000 from 1024.
+
+* The test suite now programmatically queries `pyquil.list_quantum_computers()` for valid QPU lattices for integration tests, and additional gradient integration tests have been added.
+
+* The minimum required version of PennyLane has been increased to v0.9 due to plugin API changes in PennyLane.
+
+---
+
+# Release 0.8.0
+
+* Added parametric compilation for `forest.qvm` and `forest.qpu`, leading to significant speed increases when performing optimization
+
+* The plugin has been ported to use the new [`QubitDevice`](https://pennylane.readthedocs.io/en/stable/code/api/pennylane.QubitDevice.html) API for plugins, resulting in a cleaner interface with built-in support for multi-qubit observables.
+
+* Bug fixes to allow the plugin to work with pyQuil >= 2.16
+
+* Operator estimation on `forest.qpu` now works with both 1 and 2 qubit gates
+
+* Adds a converter so that pyQuil and Quil programs can be loaded as differentiable PennyLane templates
+
+---
+
+# Release 0.6.0
+
+* Added ability to return multi-qubit expectation values to all devices
+
+* Added variance support
+
+* Replaced dense matrix expansion with a tensordot implementation
+
+* Added support for `samples`
+
+* Readout Error Mitigation using Operator Estimation
+
+* Updates the plugin to work with PyQuil 2.13 and PennyLane 0.6
+
+---
+
+# Release 0.3.0
+
+### New features
+
+* Updated to support PyQuil v2.9.0 and PennyLane v0.4.0. Note that PennyLane-Forest now requires PennyLane>=0.4
+
+* The observable `qml.Hermitian(A, wires)` can now be measured on an arbitrary number of wires. That is, you can now pass a matrix A of size `[2**N, 2**N]` which acts on `N` qubits (i.e., `len(wires)==N`).
+
+* Adds support for the `qml.var()` measurement return type provided by PennyLane v0.4.
+
+---
+
+# Release 0.2.0
+
+* Using any of the available lattices at any given time, instead of a specifically named one
+
+* updated minimum pyquil version requirement to 2.7
+
+* added support for pyQVM
+
+* removed 2.4 changes
+
+* Updating compiler urls
+
+* Replacing old lattice with new
+
+* pyqvm working without the compiler
+
+* Updating compiler urls
+
+* Replacing old lattice with new
+
+* added build and documentation badges
+
+* Remove the LocalQVMCompiler from the tests
