 This document contains a summary of the new features, changes, fixes and known issues in each release of Trusted
 Services.
 
+Version 1.0.0
+-------------
+
+The first stabilised release of the project from previously prototype releases ready for product use.
+
+Feature Highlights
+^^^^^^^^^^^^^^^^^^
+
+- Introduce the :doc:`Block Storage Service </services/block-storage-service-description>`. The Block Storage service
+  can be used to share a block-oriented storage device such as a QSPI flash between a set of independent secure world
+  clients.
+
+- Introduce the :doc:`Firmware Update Service </services/fwu/index>`. The FWU service implements the Update Agent
+  defined in the `Arm FWU-A specification`_ and allows replacing FW components with newer versions.
+
+- Refactor FF-A UUID policy. Reinterpret the FF-A UUID to identify the protocol supported by TS SP instead of the
+  service. This removes the maintenance burden of keeping an up to date UUID list in the service locator. All SPs start
+  using the same protocol UUID, and implement a new discovery service (see the next point).
+
+- Overhaul the RPC protocol. The main driver is to remove the single shared memory region limitation, which does not
+  allow separating shared regions of clients running over Linux in the user-space. The second driver is to add
+  versioning support to the RPC layer.
+
+    - Allow multiple shared memory regions between endpoints.
+    - Implement the discovery service in the RPC layer.
+    - Allow assigning a UUID to interfaces. This mechanism replaces the protocol identifier used earlier. Each protocol
+      of a service is represented as a dedicated interface.
+    - Add versioning support to the RPC layer.
+
+- Refactor the discovery service. The is removing the runtime overhead of memory sharing during the discovery and
+  decreases code size and duplication using the same code for service discovery.
+
+    - Implement the discovery service in the RPC layer for efficiency reasons.
+    - Implement service identity discovery for all services.
+    - Remove the encoding type entity and use service UUIDs to represent the serialization type.
+    - Service property discovery is to be implemented in the future.
+
+- Add support for the Corstone-1000 platform. For more information about this platform please see: `Corstone-1000 product homepage`_
+
+- SPs now indicate support of :term:`Normal World` interrupt preemption capability in their SP manifest and allow the SPMC to enable
+  preemption if possible. This removes NWd interrupts being disabled for long periods due to long service calls.
+
+- Add support for the Armv8-A CRC32 feature for :term:`Secure World` and :term:`Normal World` components.
+
+- Extend FF-A support with:
+
+    - FF-A v1.1 boot protocol between the SPM and SPs.
+    - FF-A v1.2 FFA_CONSOLE_LOG call. This allows SPs to emit log messages in an SPMC agonistic way.
+
+- Improve the build system to allow setting the build steps of external components to be verbose.
+
+- Add support for runtime (dynamic) psa-acs test case configuration.
+
+Updated external components
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+- MbedTLS version integration into the Crypto service is updated to v3.4.0.
+- The PSA Arch test is updated to version `74dc6646ff594e131a726a5305aba77bac30eceb`.
+
+Breaking changes
+^^^^^^^^^^^^^^^^
+
+- The new RPC ABI is not backwards compatible and needs recent version of all depending components.
+
+Resolved issues
+^^^^^^^^^^^^^^^
+
+- The new RPC version allows having multiple shared memory regions between endpoints. This allows each NWd client
+  running in Linux user-space to use a dedicated buffer.
+
+Known limitations
+^^^^^^^^^^^^^^^^^
+
+  - Crypto key store partitioning by client is not yet supported. This means multiple clients running at the same FF-A
+    endpoint use a shared key space.
+  - The full firmware update process implementation and testing is work-in-progress. The FWU process relies on the
+    cooperation of multiple FW components owned by multiple FW projects. Some 3rd party components do not implement the
+    needed features yet and thus, the FWU service was validated in "isolation" and exercised by TS test on the FVP
+    platform and on the host PC only.
+  - Service property discovery is not implemented yet.
+  - Discovering the maximum payload size of a service is not supported yet and buffer sizes are hardcoded.
+
