-This is the third public release of NetBSD for the DECstation and
-DECsystem family of computers.  
-
-This release includes support for either mips1 (r2000, r3000) and
-mips3 (r4000, r4400, r4600) CPUs. mips1 and mips3 support can be
-configured into a single kernel.  NetBSD 1.3 can be installed onto
-DECstation 5000/50, 5000/150, 5000/260, or 5900 models, as well as all
-previously-supported hardware.
-
-Though stable NetBSD/pmax snapshots with shared-library support have
-been available for over a year, this is the first full NetBSD/pmax
-release to ship with ELF shared libraries.  Much of the user-space
-support for this is due to work by Per Fogelstrom (pefo%OpenBSD.ORG@localhost)
-and ported to NetBSD by Manuel Bouyer.
-
-Ultrix emulation for Internet applications is improved over NetBSD
-1.2.  The Ultrix `ifconfig' command and multicast applications now
-work in Ultrix compatibility mode.  A ecoff-format NetBSD kernel in an
-Ultrix root filesystem should boot multi-user, though this is not
-recommended as an installation method.
-
-A bug in mips interrupt handling from 4.4BSD, which could cause
-`remrunque' panics under heavy load in both NetBSD prior to 1.2E and
-OpenBSD, is fixed in this release.
-
-There are yet more enhancements for the 4.4bsd-Lite/pmax SCSI drivers,
-which now correctly probes newer, faster, SCSI-2 disks, and handles
-large transfers (up to 64K) on 3100s.  Intermediate copies of disk I/O
-on IOASIC-based machines are eliminated, yielding a modest improvement
-on old disks like the rz25, and a bigger improvement on faster disks.
-
-Kernel performance tuning includes lower system call overhead, a
-faster bcopy() routine, faster IP checksumming code, and other
-imrprovemnts. These combine to show a dramatic (e.g., 1.5x-2.5x)
-improvement on microbenchmarks like the lmbench suite, and a modest
-improvement on larger benchmarks like kernel builds.

+This is the fourth public major release of NetBSD for the DECstation
+and DECsystem family of computers.  Significantly, this is the first
+release for the pmax that builds completely from in-tree source code.
+Some other pmax-specific changes from the 1.3 release include:
+.Bl -bullet
+.It
+A much easier-to-use ramdisk-based install procedure.
+.It
+New two-stage disk bootblocks that can load a.out, ECOFF
+and ELF kernels.
+.It
+a.out kernels are no longer built.  ELF is the preferred format
+for kernels loaded off disk, and ECOFF kernels are still required
+for netbooting.  a.out kernels will still boot.
+.It
+Better support for SFB graphics cards running at
+different resolutions.
+.It
+NetBSD/pmax now uses the X11R6 Xserver.
+.It
+Mouse problems in X on 5000/xx machines have been significantly
+reduced.
+.It
+Some improvements in the SCSI driver for the 5000/200 (although
+some problems are still thought to exist).
+.It
+scc serial driver will work up to 115.2k bps on some
+systems.
+.It
+Reworked model-dependent code, including support for 5100 (but not
+recently tested on this machine).
+.It
+Crash dumps now work.
+.It
+Switched to in-tree ld.elf_so.
+.It
+Breakpoints in gdb work more reliably for R3000 systems (although
+there still may be some problems with R4X00 systems).
