New features/updates

Prometheus FireStorm PCI bridge emulation
Release raw input devices when GUI is open (except during input Test/Remap) or when debugger window is active. Allows Windows shortcut keys like Win+E to work without need to unfocus the window.
Added Misc panel option to disable default on screen keyboard gamepad button 4 mapping.
Some uae-configuration (and other similar) debugging logging messages automatically opened the console window. Now only entering debugger will open it.
Added “Always on (Fixed only)” sound filter option. This enables A500 fixed filter but never enables “led filter”. (A1200 does not have fixed filter, only “led” filter)
Replaced old Windows 2000 compatible Windows clipboard handling with newer, simpler and more reliable method introduced in Vista.
Allow also 68020+ CPUs to fetch instruction words from custom chipset space. Only if more compatible is set. If some program really wants to do something weird like execute code located in AGA palette registers ?
Lightpen/gun cursor in any edge of screen: lightpen/gun not pointing at the screen = position can’t be read by the program.
Statefile shortcut keys now select current config file name as a base statefile name (for example, if “test1.uae” config file is loaded, SHIFT+END+0 will save statefile as “test1.uss”. Quickstart mode config still uses original default “default.uss”)
Both “SaveImage” (automatically created ext adf when write-enabling non-writable image like ipf) file extension variants are now detected automatically when checking if file exists. Paths panel SaveImage mode option now only affects generated file name when new saveimage is created.
Added LDP-1450 laserdisc player OSD font emulation. Fixes laserdisc arcade game Platoon (Nova) previously missing “YOU’RE HIT!!” messages. (All OSD graphics are generated by Amiga except this message!)

Some hardware emulated RTG boards had flickering colors during horizontal panning (>8 bit modes only)
Fixed ECS Denise superhires mode hires sprite pointer strange odd/even horizontal movement.
Fixed pre-KS 1.2 HDF/directory filesystem boot. Broke long time ago.
Multi-monitor active state was not fully reset when system was hard reset. (Multimonitor window was open -> hard reset -> window didn’t open anymore again)
If x86 bridgeboard SVGA and also other hardware emulated RTG board was active and END+F9 was used to switch monitors: both monitors’ output was drawn in same window, causing corrupted graphics and possibly also crash if monitor sizes were too different.
It was not possible to write and read ECS/AGA genlock transparency bit in color registers. Was broken long time ago.
Delay ALG LDP seek complete status reply slightly. Fixes laserdisc arcade game Platoon (Nova) few second hangs.

Magic mouse Windows cursor to Amiga mouse sync partially fixed.
Window corners now work as drag’n’drop hot spots for different floppy drives. (top/left=0, top/right=1, bottom/left=2, bottom/right=3).
68020 + memory cycle exact hung the emulator in some situations.
Reading CIA interrupt status register in a very tight loop generated spurious interrupt(s) in certain situations.
Softfloat mode with unimplemented FPU emu ticked didn’t disable 68040/060 unmasked interrupts, confusing 68040/68060.library and possibly causing it to return incorrect values.
Some CHD CD images didn’t mount correctly.
uaehf.device HD_SCSICMD didn’t set scsi_SenseActual. Also set io_Actual=30 (=sizeof(struct SCSICmd))

“Minimize when focus is lost” incorrectly activated when switching modes in some situations.
“Minimize when focus is lost” minimized main emulation window when GUI was open and main window lost focus.
If CPU panel FPU mode select menu was active and then some other panel was opened: JIT was switched off.
CD audio play from real/virtual CD (not from directly mounted image file) didn’t restart correctly if audio settings changed.
Only some emulated SCSI controllers flashed CD led when emulating a CD drive.
input.keyboard_type was always read as Amiga keyboard. If PC layout was set as default, keyboard layout was read incorrectly from config file.
Amiga reset during active RTG rendering in RTG Multithread mode could have caused a crash.
RTG Multithread mode display refreshing was unreliable in 8-bit modes when palette changed.
Finally fixed corrupted drag and drop graphics in Harddrives and Disk Swapper panel.
When inserting previously connected USB input device, previous device type (Gamepad, CD32 pad etc) and autofire mode (if any) was not restored.
Clipboard sharing could have attempted to transfer data to Amiga side after program had taken over the system, possibly overwriting memory.
Environmental variables (%variable%) in paths are not anymore resolved immediately when config is loaded but only when needed without modifying original path, preserving original path if config file is saved again.

CHS-only IDE drives can now be mounted in emulation and they appear with real size and geometry when using USB adapters that allow identity read but does not support CHS (like common JMicron based adapters).
New emulated expansions

Elsat Mega Ram HD
A.L.F.3
Progressive Peripherals & Software Zeus 040

Requires hardware level 9.1 or higher, which means most Windows 7 capable GPUs are supported.
All Direct3D9 mode features supported (overlays, masks, custom shaders)
Variable sync (G-Sync, possibly also FreeSync) supported in windowed mode.
Many D3D9 custom shaders are supported automatically, some require manual modifications to work in Direct3D 11 mode.

Simple box art/screenshot config file support.
If Wait for Blitter is enabled and blit size makes no sense, don’t wait. Fixes long delay in Vital / Mystic.
Added “CIA 391078-01” advanced chipset checkbox. This CIA revision has a bug in IO port output mode, reading output mode port will always read output mode data state. Other models, including original DIP 8520, 391078-02 and Akiko internal CIAs read IO pin external voltage level as documented. This can affect “bad” mouse left button/joystick fire button reading code (not working or stuck button). Used in A600. A1200/A4000 can have -01 or -02 revision.
Added ATAPI Tape drive emulation.
CD SCSI emulator READ CD-DA and READ CD-DA MSF commands emulated.

Bugs fixed:
It was not possible to override Z2 RAM board autoconfig data if board had built-in manufacturer/product ID defaults.
It was not possible to change existing path with Select Directory/Select Archive or Plain File buttons.
Fixed 64-bit version random crashes that usually happened with some shell extensions.
Z3 RAM in manual mode was completely broken.
UAE directory harddrive/hardfile KS 1.2 autoboot hack didn’t work without extra reset if UAE autoconfig board wasn’t first board in autoconfig chain.
68030 data cache emulation corrupted data if write was cached, write size was word or long and address was odd.
68040/060 without FPU: many FPU instruction F-line exceptions generated incorrect stack frames.
ECS Denise BPLCON2 ECS-only bits (for example KILLEHB) were masked unless AGA was also selected.
Obsolete IDE FORMAT TRACK command fixed.
GamePorts panel custom mapping incorrectly parsed joystick autofire state from config file.
Directory filesystem ACTION_SET_DATE failed to change date stamp if file was read-only.
68020 memory cycle exact CPU speed slider is again partially working, CPU speed can be reduced but not increased.
GamePorts panel custom mapping incorrectly parsed joystick autofire state from config file.
uae-configuration joystick port (joyportx) modification only queued but didn’t apply changes.
uaeserial.device crash fixed. DTR/RTS state now match serial.device behavior when device is opened.
Fixed uaegfx VRAM size check, some modes that almost filled whole VRAM didn’t appear in resolution list.
uaenet.device didn’t close low level ethernet handles when Amiga was reset, causing duplicate packets.
Bitplane overrun condition triggered incorrectly in rare situation where bitplane DMA is enabled after DDFSTOP on OCS
Tape drive emulation fixes. Fixes Amix install error if last file on tape was selected for install.
AVI recording bug fixes and updates:
First avioutput recorded frame was sometimes partially corrupted.
When saving state with avioutput active: last frame before state save was not recorded.
Number of avioutput frames buffered (waiting for compression thread processing) counter was reset periodically which caused lost frames (and leaked memory) in recorded video if CPU was not fast enough.
Delay initialization until first display frame or sound buffer recording request comes, previously “before filtering” option may have used wrong display size in some situations.
Uncompressed video selection is not forgotten anymore.
First frame was not rendered (and also not recorded) if statefile was restored when emulation was already running.
If emulator state was changed (debugger breakpoint, statefile save etc..), last frame before state change was not recorded.
File splitting (2G limit) incorrectly flushed sound buffers causing random sound glitches.
Added -max_avi_size <bytes> -command line parameter to set split size.
If recording was started and GUI was never opened in same session, sound recording rate become 44100Hz, causing AV syncronization issues if real rate was not same.
