Secure storage: improve integrity checking of the REE and SQL filesystems by adding a hash tree on the internal data structures. Any external modification is detected, except full rollback. Fixes #1188.
The linux driver will set the ‘privileged’ flag (TEE_GEN_CAP_PRIVILEGED) on the device intended for use by tee-supplicant. Fixes #1199.
RPMB: don't try to program the RPMB key by default
Fix “make clean” error cases
Fix issue when resetting persistent storage enumerator #1332

Related to this, the string format for UUIDs has changed in tee-supplicant, so that TA file names now follow the format defined in RFC4122 (a missing hyphen was added). The old format is still supported, but deprecated, and will likely be removed with the next major release.
Drop write permission to non-writable ELF segments after TA loading is complete.

Aarch64: mask all maskable exceptions before doing a normal return from call.
Device Tree: add no-map property to OP-TEE node in reserved-memory.
LibTomcrypt: fix CVE-2016-6129
In the list below, standard means that the xtest program passed with its default configuration, while extended means it was run successfully with the additional GlobalPlatform™ TEE Initial Configuration Test Suite v1.1.0.4.
If a platform is not listed, it means the release was not tested on this platform.
New supported platforms:
GCC5 support
Non Linear Mapping support: In OP-TEE kernel mode, the physical to virtual addresses was linear until this release, meaning the virtual addresses were equal to the physical addresses. This is no more the case in this release.
Font rendering routines have been introduced in order to ease an implementation of Trusted UI.
File Storage: Possibility to use the normal world filesystem and the RPMB implementations simultaneously.
AOSP: There is a local manifest to build OP-TEE into an AOSP build, running on HiKey. Please refer to the README in that repo for instructions.
OpenEmbedded: In addition to the makefile-based build described in the optee_os README, there is an OpenEmbedded-based build that supports Qemu (32-bit), FVP (64-bit), and HiKey (64-bit). Please refer to the README in that repo for instructions.

Note that the following platform has not been tested:
Generic driver: A new generic TEE driver is in the process of being upstreamed. In this release, OP-TEE/optee_linuxdriver is no more used. Instead, linux v4.5 is being patched using the proposed Generic TEE Driver, as it can be found in https://github.com/linaro-swg/linux/tree/optee
RPMB support: Secure Storage can now use Replay Protected Memory Block (RPMB) partition of an eMMC device. Check the full documentation

Softfloat library: floating point support is now available in 32bits TA.
Support running 64-bits TA: on ARMv8-A platform, TA can be compiled in AArch32 and/or in AArch64 in case the core is compiled in AArch64. An example can be found in HiKey configuration file. Using the following excerpt code, the user TA libraries are compiled in both AArch32 and AArch64, and can be found in out/arm-plat-hikey/export-ta_arm32 and out/arm-plat-hikey/export-ta_arm64
ta-targets = ta_arm32
ta-targets += ta_arm64
Concurrent TA support: multiple TA can run in parallel on several cores.
New tests added in xtest test suite: concurrent TA (xtest 1013), floating point tests (xtest 1006 and os_test TA) and corruption file storage (xtest 20000)
