 # Changelog
 
-## 4.0.0-rc.32
+## 4.0.0
 
-### Breaking Changes
-
-- Use `ExecutionOptions` parameter to configure how jobs are submitted and retrieved from a QPU. This replaces the `use_gateway` flag on `QCSClient.load()` has been removed. (#1598)
-- The `QuantumComputer`'s `run` method now takes an optional `MemoryMap` parameter. This mapping takes memory region names to a list of values to use for a run. This replaces the need to use `write_memory` on `Program`s between runs.
-- use qcs-sdk-python implementation of conjugate_pauli_by_clifford and generate_randomized_benchmarking_sequence (#1557)
-- remove qcs-api-client dependency (#1550)
-- Removes the compatilbility.v2 subpackage
-
-### Features
-
-- increase gRPC message size limit (#1610)
-- support translation options for QPUCompiler (#1590)
-- remove v2 compatibility layer (#1475)
-- gracefully handle error when QPU unavailable for engagement (#1457)
-
-### Fixes
-
-- Initializing a QPU with an `endpoint_id` should no longer raise an exception
-- `Program.copy_everything_except_instructions()` no longer adds declarations to the instructions property (#1612)
-- specify `quil` as a dependency
-- `copy_everything_but_instructions` now correctly copies `DECLARE` statements (#1600)
-- get_qc will use the given client_configuration
-- Remove calibrations from program before sending them to a QVM (#1592)
-- Replace `retry`, loosen `networkx` requirements, ensure adding programs don't mutate the first
-- Parametric DefGates and upper case function call expressions will no longer fail to parse. (#1589)

-### Breaking Changes
-
-- The `QuantumComputer`'s `run` method now takes an optional `MemoryMap` parameter. This mapping takes memory region names to a list of values to use for a run. This replaces the need to use `write_memory` on `Program`s between runs.
-- use qcs-sdk-python implementation of conjugate_pauli_by_clifford and generate_randomized_benchmarking_sequence (#1557)
-- remove qcs-api-client dependency (#1550)
-- Removes the compatilbility.v2 subpackage
-
-### Features
-
-- support translation options for QPUCompiler (#1590)
-- remove v2 compatibility layer (#1475)
-- gracefully handle error when QPU unavailable for engagement (#1457)

-## 4.0.0-rc.10
+The 4.0 release of pyQuil migrates its core functionality into Rigetti's latest generation of Rust SDKs. With this comes access to new features, improved performance, stronger type safety, and better error messages. While this is a significant change for the internals of pyQuil, we've attempted to keep breaking changes to a minimum. Unless necessary, we've chosen to only remove redunant or lesser used features that aren't likely to bother most users.
 
 ### Breaking Changes
 
-- Use qcs-sdk-python implementation of conjugate_pauli_by_clifford and generate_randomized_benchmarking_sequence (#1557)
-- Replace `qcs-api-client` with `qcs-sdk-python` (#1550)
-- Removed the `compatilbility.v2` subpackage (#1475)
+- Replaced the `qcs-api-client` dependency with `qcs-sdk-python`. Consequentially, the former's `QCSClientConfiguration` has been replaced by the latter’s `QCSClient`. The `QCSClient` class can be imported from the `api` module.
+- Removed the `compatibility.v2` sub-package.
 - Removed the `EngagementManager` class as RPCQ is no longer used.
 - Python 3.7 is no longer supported.
+- The environment variable overrides for `quilc` and `QVM` URLs have been renamed to `QCS_APPLICATIONS_QUILC_URL` and `QCS_APPLICATIONS_QVM_URL`, respectively.
+- The `QuantumComputer`'s `run` method now takes an optional `memory_map` parameter. This mapping takes memory region names to a list of values to use for a run. This replaces the ability to use `write_memory` on `Program`s.
 
 ### Features
 
-- pyQuil now uses `qcs-sdk-python` (bindings to the QCS Rust SDK) for compiling and executing programs.
-- RPCQ has been removed in favor of OpenAPI and GRPC calls. This enables:
-    - Better performance
-    - Better error messages when a request fails
+- pyQuil now uses `qcs-sdk-python` (bindings to the [QCS Rust SDK](https://github.com/rigetti/qcs-sdk-rust/)) for compiling and executing programs.
+- With the exception of requests to a `quilc` server, RPCQ has been removed in favor of OpenAPI and gRPC calls. This enables:
+	- Better performance
+	- Better error messages when a request fails
 - The improved Rust backend allows on-demand access to a QPU.
+- The new `QPUCompilerAPIOptions` class provides can now be used to customize how a program is compiled against a QPU.

+
+### Breaking Changes
+
+- The `QuantumComputer`'s `run` method now takes an optional `MemoryMap` parameter. This mapping takes memory region names to a list of values to use for a run. This replaces the need to use `write_memory` on `Program`s between runs.
+- use qcs-sdk-python implementation of conjugate_pauli_by_clifford and generate_randomized_benchmarking_sequence (#1557)
+- remove qcs-api-client dependency (#1550)
+- Removes the compatilbility.v2 subpackage
+
+### Features
+
+- support translation options for QPUCompiler (#1590)
+- remove v2 compatibility layer (#1475)
+- gracefully handle error when QPU unavailable for engagement (#1457)

+## 4.0.0-rc.10
+
+### Breaking Changes
+
+- Use qcs-sdk-python implementation of conjugate_pauli_by_clifford and generate_randomized_benchmarking_sequence (#1557)
+- Replace `qcs-api-client` with `qcs-sdk-python` (#1550)
+- Removed the `compatilbility.v2` subpackage (#1475)
+- Removed the `EngagementManager` class as RPCQ is no longer used.
+- Python 3.7 is no longer supported.
+
+### Features
+
+- pyQuil now uses `qcs-sdk-python` (bindings to the QCS Rust SDK) for compiling and executing programs.
+- RPCQ has been removed in favor of OpenAPI and GRPC calls. This enables:
+    - Better performance
+    - Better error messages when a request fails
+- The improved Rust backend allows on-demand access to a QPU.
