A simple addition with significant performance implications:
...
sicslowpan tags TCP packets with the PACKETBUF_ATTR_PACKET_TYPE_STREAM
flag, which makes the underlying power-saving MAC layer keep the radio
on for some time after transmitting the packet. This allows reply
packets to be processed directly, significantly increasing TCP latency
and throughput.

A new optimization to X-MAC: senders now keep track of when neighbors
...
last were known to be awake. When sending a packet, a sender does not
start to send strobes until the neighbor is expected to be awake. This
reduces power consumption for senders and decreases the contention in
the network as there are less packets in the air. Additionally, the
ACK optimization was improved so that data/ack exchanges now are
more efficient.

Introduced two garbage collection mode: greedy and reluctant.
...
The greedy GC mode attempts to erase as many sectors as possible, and
it is therefore a slow operation, since the flash driver must wait
for about a second after erasing one sector. The former behavior was
to always do a greedy GC if file reservations fails due to lack of space.
The new reluctant GC stops after erasing one sector, and therefore
we often do not have to wait if there is no file system operation
in the time while the sector is being erased. We call the garbage collector
using this mode when removing a file that is not a micro log file, since
the remove function is called recursively for micro log files that are
erased because the corresponding ordinary file is erased.
This change increases the coffee test (examples/sky/test-coffee.c) speed
from 9 to 5 seconds.

With dynamic loading enabled the function ctk_textentry_input_null() lives in the persistent core while the macro CTK_TEXTENTRY() is typically used in loadable modules. So ctk_textentry_input_null() needs to be dynamically resolved.
...
On Win32 dynamic resolving isn't done by patching the dynamically loaded segments. Rather the code generated by the compiler for accessing symbols declared with __declspec(dllimport) is implicitly modified to actually go through pointer dereferenciations. The dynamic linker only initializes this pointers.
But with the symbol ctk_textentry_input_null becoming a pointer to a function it isn't a constant anymore and so it can't be used as initializer element - and thus breaking CTK_TEXTENTRY().
So the only viable solution seems to stick to the inversally available NULL pointer on Win32. But if there's an ugly #ifdef <platform> necessary anyway than it seems resonable to classify ctk_textentry_input_null as the special case and therefore use #ifdef SDCC:
- It saves some bytes on all non-SDCC platforms
- Is matches the exsisting inline documentation

A new experimental network primitive called an 'announcement'. An
...
announcement is an (ID, value) tuple that is disseminated to local
area neighbors. An application or protocol can explicitly listen to
announcements from neighbors. When an announcement is heard, a
callback is invoked.
Announcements can be used for a variety of network mechanisms such as
neighbor discovery, node-level service discovery, or routing metric
dissemination.
Application programs and protocols register announcements with the
announcement module. An announcement back-end, implemented by the
system, takes care of sending out announcements over the radio, as
well as collecting announcements heard from neighbors.

Reverted the timer_expired() back to the previous version (which should be correct). Removed the definition of CLOCK_LT() because it seems to only cause problems.

Fixed the CLOCK_LT again. The previous revert was incorrect: the conditional was missing due to a bad copy-and-paste on my part :(

Reverted CLOCK_LT to the previous version, which upon closer examination seems to be correct. The new version did not work correctly on the minimal-net platform.
