check for address error when new PC is set at the end of RTE, RTS and RTR
fix "move.b an,", it's not allowed and should give illegal instruction
improve stack frame for bus error and address error
allow bus control only for 030 (i.e. prevent TOS forcing 16Mhz at boot with higher CPU levels)
Memory:
TT-RAM / 32-bit addressing support both for TT & Falcon emulation (when using EmuTOS, this requires version 0.9.4 or later)
FDC changes:
for STX disks, fix type I commands with verify bit on tracks with no sector
for ST/MSA, check read address and read track are not beyond max track
MFP:
better emulation of GPIP, AER and DDR
MIDI:
some RX/TX interrupt conditions were not correctly handled
TDRE bit is status register more accurately handled
Video:
fix value when reading video counter $FF8205/07/09 in high res
Blitter:
when transfer ends, hog bit should be cleared in control register
DSP:
better emulation of the HREQ signal
EMULATOR:
Support for compiling with libSDL2 (experimental)

GUI and command line options to specify GEMDOS HD emulation drive (default = C:), or to skip recognized drives used by partitions on ACSI & IDE images Partition count parsed by Hatari might not match count used by Atari HD driver due to driver differences in interpreting disk MBR
Refuse to mount same HD image from multiple Hatari instances (on platforms supporting BSD flock()), to avoid corrupting them
SDL GUI:
joystick navigation in options GUI
keyboard navigation & shortcuts in options GUI
sort file selector items case-insensitively with folders first

Better detection of bottom border removal on a 60 Hz screen
support for color change during only 4 cycles
better bitmap/color alignment for STE med res overscan at 60 Hz
Set default value of nSpec512Threshold to "1" instead of "16"
Update the position of the next VBL when 50Hz and 60Hz lines are mixed
When video address is set into IO region, keep the video pointer on 24 bits
Videl changes :
correct masking of the true color palette registers
CPU changes :
Fix a case when MFP's interrupt happens during the IACK sequence for HBL/VBL
Many prefetch changes required by some game's protection
Sound changes :
Fix STE sound mixing using LMC when mixer=0 (DMA sound only)
Fix some crossbar's sound errors for Falcon
Fix Microwire's decoding of mask/data (based on official LMC1992's doc)
FDC changes :
Add configurable RPM speed for each floppy drive, the possibility to turn each drive ON/OFF and the choice between single or double sided drive
Correct timings, behaviour and status register for all commands when a drive is OFF or empty.
Rewrite the index pulse part and all the delays expressed as disk's revolution
Add support for the "Force Int on Index Pulse" command
Rewrite the DMA functions for better accuracy
Add support for IPF/CTR files by using the capsimage library
Add open source support for Pasti STX files, including random/fuzzy bits and variable length bits. Also allow to save writes to a .stx file into an additional .wd1772 file (store 'write sector' and 'write track' data)
Don't force drives A and B at $4c2, keep the values detected by TOS
Many other timing / status register improvements
GEMDOS HD emulation:
Fix: clip filenames given through GEMDOS calls to 8+3 length using first '.'
Fix: autostarting programs with GEMDOS-illegal host characters in their names
ACSI hard disk changes:
Fixed/improved READ CAPACITY and INQUIRY commands
Unsupported commands are now handled correctly
Now using fseeko() instead of fseek() for supporting large images
Other changes:
Don't enable MegaST's real time clock by default, it can cause some crashes in STF/STE mode
Improve ACIA's wait state with E clock
Add support for IKBD commands 0x11 and 0x13 (resume/pause output) and 0x17 (joystick monitoring)
EMULATOR:
SDL GUI:
Update clock speed in the status bar when changing bus speed in Falcon mode
In the floppy dialog, use a checkbox to enable/disable drives A and B and another checkbox to choose single/double sided drive
In the screen dialog, add checkbox for --desktop-st option
Add a 2nd line in the status bar, with infos on FDC, joysticks, monitor
Fix OSX performance issue caused by statusbar and overlay LED doing their own SDL_UpdateRects() calls
New command line options:

Options --drive-a-heads and --drive-b-heads to select single or double sided drives A and B
--slowdown option to increase (multiply) VBL wait times
New Native Features commands:
NF_EXIT exits emulator with given exit code
NF_DEBUGGER invokes Hatari debugger from native program
NF_FASTFORWARD sets fast forward on/off
Tracing improvements:
Add option for tracing NatFeats calls
Fix: Xbios(255) modified the given argument string
Allow BIOS, XBIOS, GEMDOS, VDI and AES tracing to be enabled without enabling also X/BIOS interception, GEMDOS HD emulation or extended VDI mode
Show PC value for traced Bios/XBios/GemDOS calls
Debugger:
Fix: release mouse in all cases where debugger can be invoked
Fix: DSP disassembler didn't in all cases show illegal opcodes correctly
Fix: "symbols" command crash when it was used during TOS bootup
Fix: TOS and cartridge addresses weren't (with all TOS versions) in address order which asserted in profile data post-processor
Fix: "next" command didn't work correctly in "hex" number base
Fix: depending on compiler/linker/assembler, DATA/BSS debug symbol offsets can in programs be either relative to their own, or to TEXT section start. If former fails, try latter when loading symbols.
New "ym" info subcommand to show YM register values
"quit" command by-passes exit confirmation dialog and takes an optional Hatari exit code value
removed limits on breakpoints and their conditions
when entering debugger, current program's DRI/GST format debug symbols are automatically read from it, if such are available
new --debug-except option to specify which exceptions invoke the debugger, and WinUAE CPU core support for -D toggle option
"next"/"dspnext" commands work like in other debuggers, they skip subroutine/exception calls, for all other instructions they works like "step" command (earlier they always moved to next instruction in memory)
"next" and "dspnext" commands support optional "instruction type" argument, which can be used (for example) to continue emulation until subroutine returns
"history" command takes optional parameter specifying how many instructions of history will be tracked
CPU & DSP profile commands have now subcommand for profiling loops
"CpuInstr" and "DspInstr" variables for count of instructions executed since emulation was last continued from debugger
In addition to "!" condition, also "" conditions can store the checked value (when both sides of conditions are identical). With above change, this can be e.g. used to detect and profile what are worst frames in games and why
New "rename" command to rename files. Useful for scripted worst frame and spinloop profiling
Address space in 'dm' command can be given like in DSP disassembly, "dm x:$100", in addition to earlier "dm x $100" syntax
Fix out of bounds memory access that could result in bad disassembly output when using the external disassembler (only "dc.w" were printed)
TOOLS:
Increased max partition size in atari-hd-image script to 512MB.
New hatari_spinloop.py script for post-processing loop profile data.
It can tell how many times loops were executed, how many times they
spinned at minimum and maximum, at which VBL those happened, and what
was the standard deviation of that.
gst2ascii supports now both section relative and TEXT section relative
DATA/BSS symbol offsets
hconsole.Main() takes now Hatari command line options as argument
AHCC/GCC/VBCC examples on using (all) Native Features APIs
Improved mingw cross-compilation support
