dear All,

The next official version -- 2016Apr1 -- of teqc is on-line:
As usual, save a copy of your current executable in case there
is some unexpected problem with the new executable.

The main changes and fixes since 2015 Nov 6 are given in detail at
but here's a very brief summary:

- This releases fixes the bug introduced on 11 Sep 2015 -- and was therefore
in the 2015 Nov 6 release -- which could result in a segmentation or memory
fault when both reading and outputting certain RINEX observation files.
(The occurrence was dependent on the size of the phase values.)

- This release fixes the differences that have developed between the
USI ("Universal Satellite Identifier") indices between Topcon TPS and
Javad JPS that have developed over time (i.e. since Topcon and Javad
parted ways).  The previous code was mostly a problem for users trying
to look at Beidou data.

- This releases fixes a bug related to the JPS and TPS message [::]
(ET, "epoch time"); since this message is not really used by teqc,
it should now be safely ignored regardless of its location in a block
of messages for any given data epoch.

- This releases fixes a strange bug when reading certain TurboBinary or
ConanBinary data that prevented some GPS ephemerides from being read
if the GPS week was greater than 1023 (as it currently is).

- This release fixes a bug that was sometimes encountered when reading raw
data when there was a navigation message logged in the previous week causing
the options '+meta' or '+mds' to incorrectly terminate teqc and indicating
to the user to use '-week' with the _following_ week, i.e. the week after
the data actually started.  This subtle bug has around since the beginning
of teqc, but just rarely encountered and it was not at all clear what the
cause was.  The effect during translation of such raw data not using '-week'
at all was minor: it would merely ignore and not translate any such navigation
message logged from the previous week.

- This releases fixes a bug related to the identification, in RINEX 2.11-ese,
of the GLONASS-K FDMA signal G3 I+Q at 1202.025 MHz when reading Javad JPS.
The correct identification should be as L7/C7/D7/S7 observables, as defined
in extended RINEX 2.11 (see http://postal.unavco.org/pipermail/teqc/2013/001492.html).

- This releases fixes another bug that has been around since the beginning
such that if the user is trying to use double-quotes on a teqc option, esp.
in a teqc configuration file, but has a syntax error, teqc should now not
crash with a segmentation or memory fault, but report the offending syntax
to the user and then gracefully exit.  E.g. in a teqc config file, now try:
-O.rv "my new firmware
as opposed to the correct:
-O.rv "my new firmware"
(On a UNIX/Linux command line, the double-quotes are being interpreted by
the shell you are using, not teqc, so the result is shell-dependent.)

- This release continues the new option paradigm for the options:
     +dump_ion, ++dump_ion
     +dump_utc, ++dump_utc
... so please consult `teqc +help` if you use any of these options, e.g.
[2385] teqc +help | grep dump_i
         +dump_i[on] .        output any ionosphere model parameters to stdout
         +dump_i[on] ..       output any ionosphere model parameters to stderr
         +dump_i[on] name     output any ionosphere model parameters to file 'name'
         ++dump_i[on] name    append any ionosphere model parameters to file 'name'
         -dump_i[on]          don't output ionosphere model parameters except to RINEX nav header (default)

Not available with this release:

- any HP-UX builds (due to a lack of access an HP-UX system for compiling)
- the Borland build for Windows (due to losing my antiquated Borland environment
   in Nov 2015 -- just days after the 6 Nov 2015 build was done); instead, use
   the Mingw-32 bit build
- the Mac OSX i5 gcc 4.2 64-bit build; instead, use the OSX i5 gcc 4.3 64-bit build


p.s. Yes, this is being released on April Fool's Day, April 1 -- just a timing
issue so we can cut this loose -- but I assure you it's 100% legitimate.
