+## [0.11.0] - 11/01/2021
+
+### Added
+- Use Python 3.9 in public CI (#599)
+- Add a new C API utility function (`DPCTLDeviceMgr_GetDeviceInfoStr`) to return the device info as a C string object (#620)
+- New Github workflow to build dpclt with nightly Intel llvm/sycl + drivers (#621)
+- Always raise SubDeviceCreationError even when sub-device counts are zero (#622)
+- Updated OpenCL interoprability code to fix build with Intel llvm/sycl bundle (#625)
+- Enabled use of default platform context extension in SYCL compilers that implement this extension (#627)
+- Implemented `dpctl.utils.get_execution_queue(queue_seq)` utility to help implementing "compute-follows data" convention for offload target (#632)
+- Improved code coverage (#619) (#542) (#631)
+
+### Changed
+- Replaced `host_device` device type with `host` in tests (#616)
+- Rework the logic in `dpctl.memory`'s `copy_from_device` method to work correctly with `host` device (#618)
+- Use `dpctl.device_type.host` instead of `dpctl.device_type.host_device` (#626)
+- Reinstate deprecated `sycl::program` and that was conditionally removed from open source DPC++ toolchain (#633)
+- Use `LoadLibraryExA` instead of `LoadLibraryA` to mitigate a possible DLL injection issue when we load the Level zero DLL on windows (#636)
+- Github coverage workflow is changed to use oneAPI 2021.3 instead of latest to work around broken profiling instrumentation in DPC++ 2021.4 (#614)
+- Update build dependencies for NumPy (#641)
+- Use "readelf" on SYCL's `pi_level_zero` library to find out and use the exact name of `ze_loader.so` in SyclInterface library (#617)
+
+### Removed
+- Removed use of DPC++ features deprecated in 2021.4 and open source Intel llvm/sycl compiler (#603)
+
+### Fixed
+- Suppress errant CMake log (#610)
+- Fixes to compile dpctl using Intel llvm/sycl compiler (#603)
+- Fix for the hang is to avoid passing `nullptr` argument to `sycl::queue::prefetch` (#612)
+- Fixed the logic to return device count (#623)
+- Enabled building of C extensions with dpctl by including header defining `bool` type for C compilers (#604)
