• Fix stream files formats export : No more glitch after the first revolution index. (Fix SCP and KF export).

• Sectors recovery support - Can be disabled/enabled with the FLUXSTREAM_SECTORS_RECOVERY variable.
  This feature try to automatically recover/fix bad sectors with copies present in others stream revolutions.

• Default pulses timing jitter tolerance increased from 10% to 14% (Config file).

-> Kryoflux writer : stream to stream conversion : Don't align output stream to the next index.

-> SCP writer : stream to stream conversion : Don't align output stream to the next index.

-> SCP loader : Fix broken support of SCP images with more than 5 revolutions.

-> Track display : Fix possible infinite loop : check the bitrate value and stop + report if needed.

-> HFEv3 loader : Support RAND_OPCODE right after SKIPBITS_OPCODE.

-> New X68000 DIM file image loader.

-> New Apple II 2MG file image loader. (WIP - To be completed)

-> XML raw loader : Fix images last sector loading.

-> Track editor : New "insert" and "remove" track operations.

-> HFE writers : New "HFE_WRITER_WRITENOTALLOWED" parameter : Set it to 1 to write protect the exported hfe files.

6 February 2023 : HxCFloppyEmulator 2.14.4.1

-> Windows : Turn the process in high priority when the USB HxC Floppy Emulator is detected.
Fix most of the Sync lost events.

-> XML generated disks : Clear the internal tracks status -> fix the command line tool.

-> Hard-sectored H8D Heathkit images: Fix odd tracks main index skew.

-> QuickDisk files loader : Support "HxC-like-but-not-exactly-hxc" QD images files.

-> DiscFerret DFI Loader : New DFILOADER_SAMPLE_FREQUENCY_MHZ parameter to change
the default sample frequency.

-> HxC stream (Pauline) : Support CLV convertion parameters :

- FLUXSTREAM_IMPORT_PCCAV_TO_MACCLV (Dump drive's CAV RPM)
- FLUXSTREAM_IMPORT_PCCAV_TO_C64CLV (Dump drive's CAV RPM)

-> SCP writer : The "Disk Type" field can be forced in the configuration file and the "SCPEXPORT_DISK_TYPE" variable.

-> Stream files writers (SCP/KF Raw/...) : Direct stream to stream support

If the current loaded tracks have a stream dump in memory then	
these streams are now just resampled and then exported to the stream file.	
If you want to use the old behavior and export the analyzed tracks instead then
set the "FLUXSTREAM_STREAM_TO_STREAM_CONVERT" variable to 0.

-> Stream analyzer : Bands mode "PLL" -> better Victor 9000 disks support (Work-in-progress)

-> Stream analyzer : Better Apple II and Macintosh support.

-> IMD File Writer : Fix track type when no supported sector are present on the track.

-> MSA File Writer : Don't write the last unformatted tracks.

-> Kryoflux Import : (WIP) Possible missing last index workaround.
-> Kryoflux writer : Possible dead lock fixed.

-> FDX support added : Revision 3 file format (standard and Raw/stream variants supported)
-> Raw FDX writer support added.

-> 86Box 86F support added : (WIP)

-> FD loader : Fix sectors side ID : All of them should use the ID 0.

-> Logic analyzer capture loader:

Can now load tracks captured with a simple logic analyzer. (Saleae logic analyzer or similar).

The current state/limitations are :

Need only 2 jumper wires : data (floppy pin 30) & index (floppy pin 8).
Load only a track at a time.
The sample rate is set by default at 16MHz. This can be changed through the "LOGICANALYZER_SAMPLERATE" variable.
The floppy data signal is mapped by default to the bit 0. This can be changed through the "LOGICANALYZER_DATA_BIT" variable.
The floppy index signal is mapped by default to the bit 3. This can be changed through the "LOGICANALYZER_INDEX_BIT" variable.
The supported input file format is a raw 8bits binary format (change the file extension to ".logicbin8bits").
Each byte in the file is a sample.

How to use it ? :

Connect the ground, data and index wires : machine ground to vss/gnd wire, floppy pin 30 to wire 0, floppy pin 8 to wire 3.
Start the machine, start the logic analyzer software. Start the capture and on the machine use any software/way to read a particular track.
The track should be read during at least to 2 revolutions ( 3 index pulses ). Save the dump in raw binary mode.
Change the binary dump file extension to ".logicbin8bits".
Before loading the file into the hxc software you may need to set the LOGICANALYZER_IMPORT_START_OFFSET and 
LOGICANALYZER_IMPORT_END_OFFSET	variables to define the region of interest in the file. 
You can use PulseView or similar software to roughly get the values to use.

TODO / Work in progress :

- Add the xx.y file naming convention to load multiple track files (xx=track number, y=side number)
- Add the dir,step,side, track 0 signals support to load a whole disk from one single file.
