DO NOT USE ON A4092

NOTE: This release has an alignment problem with the NCR script on the A4092.
If you have an A4092, please use release v42.39 instead.

Highlights

Improves driver stability by fixing nested interrupt-disable handling,
releasing interrupt protection on SCSI polling timeouts, and correcting
an out-of-bounds DMA test buffer.
Loads ROM and Kickstart filesystems only when matching media needs them,
keyed by DosType.
Adds TinySetPatch to the utilities disk and replaces its shell-heavy
startup banner with a faster native helper.
Updates the bundled ODFileSystem to v0.7.0 and devtest to v1.9.

Balance every nested Disable() with Enable() in the SPL wrappers.
This prevents interrupt nesting from leaking until interrupts remain
masked and the machine stops.
Release the SPL before resetting the SCSI chip when either polling path
times out.
Fix the ncr7xx DMA test's source-buffer arithmetic, which could write
several kilobytes beyond its allocation and corrupt memory.
Run the A4770's 53C770 at a safe 80 MHz SCSI clock, limit DMA bursts to
eight transfers, and apply the configured cache-line and snoop settings
after reset.
Use the documented boot-option defaults when battmem.resource is not
available, including enabling CD-ROM boot.
Clamp parsed printf field widths and precision to prevent integer
overflow in the firmware formatter.

Load embedded ROM filesystems and the Kickstart CD filesystem on demand
instead of registering every available filesystem at startup.
Select filesystems by DosType and cache load attempts so each matching
filesystem is initialized at most once.
Pass the relocated filesystem segment to InitResident() as the BPTR
expected by AmigaOS.
Require romtool -T when adding a filesystem to a ROM image, preventing
creation of slots that the demand loader can never select.
Correct the FileSystem.resource patch-flags documentation to include
the patched StackSize field.
Rename the boot-menu option to Scan past RDBFF_LAST and clarify
that it continues probing higher SCSI IDs after a disk marks itself as
the last device.
Update the bundled mounter with safer MBR/GPT handling, CD-ROM fixes,
wide-SCSI addressing, host-adapter ID skipping, a TD_MOTOR null-pointer
fix, and fixes for nested Forbid() use during filesystem lookup.

Improve mounting and media-change behavior, including shared-library
lifetime handling, stale volume nodes, deferred volume publication, and
empty-drive handling.
Add High Sierra, ISO 9660 multi-extent file, AmigaDOS soft-link, and
improved UDF support.
Improve directory, metadata, parent-lookup, and sequential-read
performance through caching, pooling, hashing, and batched I/O.
Improve audio CD and CD-Text support, including track-title comments and
configurable disk icons.
Raise the minimum handler stack to 16 KiB and retain a ROM build that
fits the 32 KiB filesystem slot.

Add TinySetPatch and its required MMULib CPU libraries to the bootable
utilities disk, including its updated 68030 detection.
Replace repeated shell Echo commands with a small welcome program,
reducing startup overhead while preserving the existing banner and tool
summary.
Update devtest to v1.9 with arbitrary direct SCSI commands, corrected
READ CAPACITY LUN encoding, improved capacity and sense-error reporting,
and CPU utilization reporting for bandwidth tests.

Add oemgfx.sh to convert PNG artwork into 4-bit and 5-bit Amiga bitmap
variants, previews, and an oem.bin flash blob.
Harden manufacturing date, serial number, and patch-data parsing with
explicit bounds and stricter validation.
Report single-byte SPI programming failures instead of silently ignoring
them.

Pin build, Coverity, and release workflows to the Amiga GCC 13.4
toolchain image.
Initialize submodules recursively and remove the redundant top-level
libcodesets checkout now supplied by ODFileSystem.
Resolve the Salvador compressor relative to zx0wrap, allowing the
wrapper to run outside the repository root.
Update Salvador with explicit bucket-index bounds checks.
