+RIOT-2016.07 - Release Notes
+============================
+RIOT is a real-time multi-threading operating system that supports a range of
+devices that are typically found in the Internet of Things: 8-bit
+microcontrollers, 16-bit microcontrollers and light-weight 32-bit processors.
+
+RIOT is based on the following design principles: energy-efficiency, real-time
+capabilities, small memory footprint, modularity, and uniform API access,
+independent of the underlying hardware (this API offers partial POSIX
+compliance).
+
+RIOT is developed by an international open source community which is
+independent of specific vendors (e.g. similarly to the Linux community)
+and is licensed with a non-viral copyleft license (LGPLv2.1), which allows
+indirect business models around the free open-source software platform
+provided by RIOT.
+
+About this release:
+===================
+This release was focused primarily on fixing bugs, but also adds two new 
+supported radio transceivers: CC2420 and CC2538.
+This new radio support allows to new interoperability tests with other OS, 
+allowing code size comparison and overall network performance for 
+platforms based on these radios.
+
+About 198 pull requests with about 325 commits have been merged since the
+last release and about 65 issues have been solved. 46 people contributed with 
+code in 112 days. 632 files have been touched with 19863 insertions and 
+3682 deletions.

+
+Fixed Issues from the last release
+==================================
+#3824: native: gnrc: hardcore pinging crashes.
+#4583: cpp11: clang doesn't allow mutex_t to be used with constexpr All 
+cpp11-* tests fail with clang.
+#5388: gnrc_sixlowpan_iphc_nhc: receiving NHC compressed UDP 
+packets hits assert in IPv6 (Fixed by #5281).
+
+
+Known Issues
+==========
+#3075: nhdp: unnecessary microsecond precision NHDP works with timer
+ values of microsecond precision which is not required. Changing to lower 
+ precision would save some memory.
+#3086: Max. packet length for AT86RF2XX
+#4048: potential racey memory leak According to the packet buffer stats, 
+flood-pinging a multicast destination may lead to a memory leak due to a 
+race condition. However, it seems to be a rare case and a completely filled 
+up packet buffer was not observed.
+#5005: ndp: router advertisement sent with global address Under some 
+circumstances a router might send RAs with GUAs. While they are ignored 
+on receive (as RFC 4861 specifies), RAs should have link-local addresses 
+ and not even be send out this way.
+#5007: gnrc icmpv6: Ping reply goes out the wrong interface
+#5055: cpuid: multiple radios will get same EUI-64 Nodes with multiple 
+interfaces might get the same EUI-64 for them since they are generated from
+ the same CPU ID.
+ #5230: gnrc ipv6: multicast packets are not dispatched to the upper layers. 
+(Fix exists, but was postponed)
+#5390: pkg: OpenWSN does not compile This package still uses deprecated 
+modules and was not tested for a long time.
+
+native related issues
+---------------------
+#495: native not float safe When the FPU is used when an asynchronous 
+context switch occurs, either the stack gets corrupted or a floating point 
+exception occurs.
+#534: native debugging on osx fails Using valgrind or gdb with a nativenet 
+target in OSX leads to "the network" being stuck (gdb) or the whole process 
+being stuck (valgrind).
+#334: nativenet crashes when hammered Flood-pinging a native instance 
+from more than one host (either multiple threads on the host system or multiple 
+other native instances), leads to a SEGFAULT.
+#2071; WIP: native: overdue fixes
+#4590: pkg: building relic with clang fails.
+#5432: native: valgrind fails
+
+other platform related issues
+-----------------------------
+#4560: make: clang is more pedantic than gcc oonf_api is not building with 
+clang. 
+(Partly solved by #4593)
+#4866: not all GPIO driver implementations are thread safe Due to non-atomic
+ operations in the drivers some pin configurations might get lost.
+ #5486: at86rf2xx: lost interrupts
+
+other issues
+------------
+#1263: TLSF implementation contains (a) read-before-write error(s).
+#2761: core: define default flags If a thread is created without the 
+corresponding flag (CREATE_STACKTEST), the ps command will yield wrong 
+numbers for the stack usage.
+#2927: core: Automatically select the lowest possible LPM mode Not all 
+available low power modes (LPMs) are implemented for each platform and the 
+concept of how the LPM is chosen needs some reconsideration.
+#2967: Makefile.features: location is not relevant for all features Provided 
+features for the build system should be split up into a board and cpu specific part
+#4488: Making the newlib thread-safe When calling puts/printf after 
+thread_create(), the CPU hangs for DMA enabled uart drivers.
+#4841: xtimer: timer already in the list Under some conditions an xtimer can end
+ up twice in the internal list of the xtimer module.
+#5338: xtimer: xtimer_now() not ISR safe For non-32-bit platforms.
