This shows the symbol names of stack trace in human readable text instead of addresses in hexadecimal value.
This is enabled by CONFIG_DEBUG_DISPLAY_SYMBOL, it uses ROMFS functionality and hence depends on CONFIG_FS_ROMFS. It also needs enough space.
New pthread_tryjoin_np API
This operates in the same way as pthread_join, except this is non-blocking.
New minimal configurations set
This helps to configure a target which is non-network, non-file system and non-POSIX application.
Docker build environment
TizenRT provides the easiest way to build with the use of Docker.
There is no need to install the required libraries and toolchains since the provided Docker container already includes everything required for TizenRT development.
Enhanced Features
Unlimited atexit & onexit functions
atexit & onexit functions are maintained in a list instead of fixed array. So it keeps growing and enables any number of functions to be registerd.
Multiple time interval constant for CPU load measurement
It supports to measure CPU load with 3 types of interval : short-term, mid-term and long-term through configs.
Default values of them are 2, 5 and 10 secs.
clock_t type
clock_t is a standard type of clock but systime_t is not. All of systime_t are replaced to clock_t.
Heap information of threads group defined by user
Heap information command supported information of each thread or total threads. But sometimes, heap information of grouped threads are necessary.
This feature is enabled by CONFIG_HEAPINFO_USER_GROUP and lists thread group members on CONFIG_HEAPINFO_USER_GROUP_LIST.
Fixes
Assert on heap usages
Only one case does not guarantee memory atomic operation. When top priority task tries to exit and second priority task was in memory operation, top priority task does not check whether accessing heap is available or not to free used memory. It causes non-atomic memory operation and causes an assert.
The task_exit checks availability to use memory operation before starting.
POSIX-compatible pthread key APIs
Previous pthread key APIs do not satisfy what POSIX expected on key create. To fit POSIX standard, pthread key APIs are re-implemented.
Mutex destroy failure
When pthread is on exit without unlocking mutex, mutex is not destroyed. Checking a status of pthread is added in pthread_mutex_destory.
Prevent usages of released timer
When timer APIs are called with released timer, they do not return an error. Checking timer validation is added to prevent use of released timer.
Fix month index
A range of month is 0~11, not 1~12 so that clock API has a month value with 1 subtracted from config.
Missing signal setting on restarted task
Restared task blocks all of signals because of missing set signal.

New debug script support
The g_var_profiler script shows variables which size is greater than input argument for RAM static footprint.
Fixes
Deadlock error of mutex on idle task has been fixed.
-1 instead of 0 as a PID element for unclaimed mutex at initialization has been used, because 0 means idle task. It causes deadlock error.
Memory corruption on data abort handling has been fixed.
Separated stack for data abort handler has been used, because data abort handler can save the information to outside of stack when stack is almost used. It causes memory corruption.
