* Mon Mar 21 2011 Eric S. Raymond <esr@snark.thyrsus.com> - 2.96~dev
Bumped maximum channel count to 32 to accommodate GPS+GLONASS devices.
API version bumped to 5, redesign finished (changes are documented
in the Client HOWTO). cgps now handles resize signals. Code can now
link with uClibc for embedded use. Various bugs in the C++ binding
have been fixed. gpxlogger can now daemonize and write to a specified
log file. A gpsd client can now set any locale it likes, and JSON
will still be parsed using the C locale matching the daemon's. Clients
are no longer required to define a gpsd_report() hook. gpsd no longer
emits probe strings to unidentified USB devices at startup.
JSON timestamps in TPV and SKY are now ISO8601 rather than seconds since
the Unix epoch; the library handles the older style backward-compatibly.
GPGST sentences are now parsed for noise statistics when a device emits them.
AIS and RTCM2 JSON dumps have device fields. JSON reports now include 50bps
subframe data if the device allows access to it. gpsdecode can now dump NMEA
GPS binary, and subframe data to JSON. The RTCM2 code now understands and
analyzes RTCM2.3 messages 13, 14, and 31, and has been checked against another
analyzer. The ancient Sager dump format for RTCM2 is abolished in favor of
a JSON profile.

The autonomous robot submarine total world domination release!
Rationalize clearing and generation of DOPs, this makes epx/epy much
more generally available. Fixed the test productions for the udev
magic and added a troubleshooting note in INSTALL. cgps now displays
epx/epy rather than eph. Speed is now always reported if our last
two fixes were good, even if the GPS didn't compute it. Reading
packets from UDP datagrams by specifying a listening address and
port is now supported, and the regression-test driver cam now be
told to force this with -u; this enables regression testing in
chroot jails where access to ptys is locked out. AIS code now
interprets message type 6 and 8 application IDs correctly as a
Designated Area Code and Functional ID pair. gpspipe has a new -T
option for setting the timestamp format. xgpsspeed is completely
rewritten in Python, eliminating some dependencies on ancient X
libraries. We now ship a Qt binding for the client library. Note
a GCC 4.2.1 optimizer bug. gpsdcode now uses | as a field separator
in -c mode, as string fields can contain commas. Corrected error
or reporting of AIS rate-of-turn fields.
* Sun Apr 20 2010 Eric S. Raymond <esr@snark.thyrsus.com> - 2.94
Error-checking in the 50bps subframe code has been greatly improved.
The Garmin GPS driver can now use libusb, if it is present, to do
device discovery. The libgps library has been split apart; the
service functions used by the daemon now live in libgpsd. This
will shave some code volume from GPSD client applications. A packaging
error that resulted in xgps not being shipped in 2.93 has been
corrected. We now have stronger checking for valid ephemeris before
extracting the leap-second offset; they should prevent many cases
where gpsd migh previously have used an invalid leap-second offset.
* Fri Apr 16 2010 Eric S. Raymond <esr@snark.thyrsus.com> - 2.93
Support for JSON dumping and parsing of AIS message types 25 and 26,
not yet observed in the wild on AISHub. Fix Debian bug #569703. by
removing non-streaming mode from the Python exerciser. Fix Debian
bug #572900 by unsetting the appropriate in-use flag in the device
array. Change the libgps default from old protocol to JSON. Add a
close() method to the C++ binding. Try to recover better from
sporadic cases of false matches to Trimble packet format from a SiRF
binary datastream. gps_poll() now returns -1 with errno not set when
the gpsd socket closes. TPV now refrains from reporting fields the
fix quality won't support. gpsmon option for listing device types is
now -L to -l can be used to enable logging (to stay consistent with
the l command). There is new FAQ material on improving fix and time
reference accuracy. New sections have been added to NMEA.txt on
error status indications and satellite IDs. New POLL command brings
back polling-mode operation. A Client-HOWTO has been added to the
documentation. gpsd no longer eats CPU when a device is unexpectedly
unplugged. Support for the TNT revolution is back (run mode only).
There is now a gpsdfake diagnostic tool that fakes being gpsd shipping
arbitrary specified data to clients.

Fix a packaging error. The new Python library module was
inadvertently omitted from the 2.91 tarball. Also, improve the json
import test slightly.
* Mon Mar 1 2010 Eric S. Raymond <esr@snark.thyrsus.com> - 2.91
We have support for NMEA GLONASS sentences, and a regression test.
Clients now get a DEVICE notification on every driver switch. It is
possible to specify a TCP/IP AIS feed such as AISHub as a data
source. Serious bitrot in the NTRIP support has been fixed - it was
probably nonfunctional for several releases before this. Fixed
buggy display of satellite-used flags in cgps. xgps is replaced by
a rewrite in Python that uses pygtk, eliminating a dependency on
Motif; also, it now displays AIS information. Uniform treatment of
display-unit defaulting and -u in xgps, cgps, and lcdgps. Support
for AIS message types 25 and 26. Support for IPv6. A numeric
instability in the earth_distance() function affecting track error
modeling has been fixed. Old protocol has been removed from the
daemon; the library still speaks it.
* Fri Dec 4 2009 Eric S. Raymond <esr@snark.thyrsus.com> - 2.90
GPSD-NG, the new JSON-based command protocol, is now deployed; as a
consequence, AIS is now fully supported in both daemon and client.
Detection of end of a fix-reporting cycle is now reliable;
accordingly data is accumulated from cycle start and the "J"
(nojitter) opoption on both server and client side is gone. We have
abandoned the gpsflash subproject since it has become apparent that
we can't do it without more vendor cooperation than we're likely to
get. Increase major version of shared library due to significant API
change. Added new driver for Motorola Oncore receivers, with help
from Håkan Johansson. gpsfake can now accept multiple logfiles,
interleaving test sentences from each. gpsd now accepts error
estimates from the NMEA $GPGBS sentence.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
localhost) were merged upstream.
* Tue Feb 10 Eric S. Raymond <esr@snark.thyrsus.com> - 2.38
Regression test load for RoyalTek RGM3800 and Blumax GPS-009 added.
Scaling on E error-estimate fields fixed to match O. Listen on
localhost only by default to avoid security problems; this can be
overridden with the -G command-line option. The packet-state machine
can now recognize RTCM3 packets, though support is not yet complete.
Added support for ublox5 and mkt-3301 devices. Add a wrapper around
gpsd_hexdump to save CPU. Lots of little fixes to various packet
parsers. Always keep the device open: "-n" is not optional any more.
xgpsspeed no longer depends on Motif. gpsctl can now ship arbitrary
payloads to a device. It's possible to send binary through the
control channel with the new "&" command. Experimental new driver
for Novatel SuperStarII. The 'g' mode switch command now requires,
and returns, 'rtcm104v2' rather than 'rtcm104'; this is design forward
for when RTCM104v2 is fully working.
position is only provided on on-machine clients. Previously, gpsd
listened on INADDR_ANY, providing position of the computer to any host
that asked. (The fix is in upstream bugzilla, with link in
patches/patch-ac.)
- Integrated Garmin Simple Text Protocol driver from Peter Slansky.
Minor fixes in error modeling and a better NaN guard stabilize the
Trimble regression tests. Remove the wired-in NTP time offset from the
NMEA driver, this could only have worked by accident and should be
set in ntpd.conf. Integrated Ashtech driver from Chris Kuethe.
- Navcom driver merged. Removed -d -f and -p options of gpsd; these
have been undocumented for a while. Make gpsd play well with pkgconfig.
Incorrect computation of VDOP when GPSes didn't supply it has been fixed.
The xgps code has been revamped and now has a much nicer interface.
Add -b (no-configuration) option as a sadly clumsy workaround for some
problems with Bluetooth receivers. Added tests for Haicom-305N and Pharos
360; separated out the tests for the unstable Trimble drivers.
32-vs-64-bit problems in the regression tests have been solved.
- Fix for byte-swapping of Zodiac control messages on big-endian hardware.
Disable iTalk by default and note that it needs to be tested. Command line
arguments can now be DGPSIP or NTRIP URLs; -d is deprecated. Added udev
rules. Address excessive processor and memory utilization on SBCs; it's
now possible to configure compile-time limits on the number of devices
and client sessions. Eliminate use of fuser(1) in gpsfake. Get gpsd
working with EarthMates again, this had been broken since 2.15. Massive
string safety audit and OpenBSD port by Chris Kuethe. J command added.
The gpsctl and gpscat tools and the gpsd.phps script were added. Switched
to lesstif from openmotif. Better autodetection of DLE-led packet
protocols (notably TSIP and Garmin binary) and of SiRFStar I and III
devices. Fixed buggy parsing and generation of PGRME.
* Fri Jun 9 2006 Eric S. Raymond <esr@snark.thyrsus.com> - 2.33-1
- Fix bad unit conversion in V output. Clean up some man-page messes.
Fixed buggy libgps parsing of multiple responses. It's now possible
to lock gpsd to a fixed speed at compile time for embedded use. Added
NTRIP support, thanks to Ville Nuorvala. O command now ships an
explicit mode field.
* Sun Mar 12 2006 Eric S. Raymond <esr@snark.thyrsus.com> - 2.32-1
- Cleanup of the xgps layout, and minor memory-leak fixes for xgps. Fix
to cope with Antares uBlox by Andreas Stricker. Minor fix to libgps
cgpxlogger. Merge cgpxlogger and gpxlogger documentation onto
the xgps(1) manual page and rename it gps(1).
this is a major upgrade (from 1.07), please check the homepage for
details
(I've played with 2.30 for a while and it worked well.)
