• Introduce ptrace-wrap, to support multi-threaded debugging in Linux

Analysis

• Add initial documentation for ARMv8 PAC instructions

• Improve MSP430 function boundaries analysis
• Detect function prefixed with __libc_ and __GI_
• Add aang to recover function names from stripped Go binaries
• C-Sky and MCore support for r2

• print class name in avra
• Fix ESIL x86-32 for ‘push esp’
• Implement API for loading interrupt handlers
• ESIL CHANGE: The == operation should not push any value back on the stack, use $z and NUMfor this

Disassembly

• Make up graph with new UTF-8 character for the backward lines

Commands

• Command repeat (prefix syntax) is now ut64
• Handle partial address seeks directly from RNum
• Add commands to print ASN1/DER/PKCS7 in normal and quiet modes (better than openssl asn1parse), added more OIDs
• Fix – Implement 1u8, 1u16, 1u32, 1u64 in RNum
• Updated help messages and new ?$? variables
• Fixes in pCx, pxr, pd-, pd--, pae, pade,..

• Fix  – Support R2_ and without prefix in r2 -H
• Add pFo, parse certs from Mach-0’s cdhash and minor X509 cleanup
• Added cmd.load: Run when binary is loaded
• Implement the _ (underscore command) to print the output of the last command

Refactoring

• Fix – Remove the use of RMemPool and update some comments for future discussion
• Enabled UBSAN (Undefined behaviour, improve stability on ARM/MIPS platforms)
• Enabled coverage checks in Travis CI, added Coveralls bot
• Enabled ASAN in Travis CI for passing tests
• Fix GCC 8 warnings
• Fix a lot of undefined behavior thanks to the r_assert API
• autogen.sh now uses r2pm to update acr
• Use more sys/indent.sh -i (supports clang-format)
• Fix a lot of memory leaks
• Fix – Rename {srwx,flags,perms} to perm. (-21 LOC)
• Unify R_IO, R_BIN, R_BP, .. into R_PERM_* using 1 letter syntax
• Huge speed up thanks to updated SDB, which fixes the hashtable implementation making it use less memory and perform better

Heap

• dmh with glibc now works without symbols
• linux_heap_glibc: fix dmhf and allows dmhf @thread_arena
• linux_heap_glibc : dmha and dmht, check threaded arenas free status

Bugs
