- Prevent a possible string overflow when reading the configuration file.
- Plug a few memory leaks.
- Refactor a lot of code.
- Replace -l parameter (specify logfile) of dcf77pi by an interactive 'L' key
which can also be used to change or disable the log file.
- New entry in config.txt, "outlogfile", to specify the the default log file
(default empty).
- Fix a bug where the hour would be wrongly considered off by one at the
moment of a DST change.
- Various bug fixes in the GUI code (only affected displaying of the data).
- Handle log files with \n\r line endings used by RISC OS (which runs on the
Raspberry Pi).
- Slightly improve output when reading from a log file.
- Update README.md
- support DESTDIR and install-strip, uninstall targets in upstream Makefile
- clean up port Makefile accordingly
- bugfix: do not accept removed 'S' command line option
- bugfix: display 'no minute' at the correct position in GUI mode
- do not leak curses memory at exit
- Provide an ncurses based interface in live mode, no changes when reading
from a log file
- Drop the -v and -S parameters, they are now part of the GUI
- add ncurses to USES
Changes:
- Add the correct number of minutes when the accumulated minute length is
more than 60 seconds (happens when e.g. the transmitter is off).
- Disallow DST changes or leap seconds if a 0 is specified for summermonth,
wintermonth, or leapsecmonths.
- Allow compilation on NetBSD.
Changes:
dcf77pi:
- Calculate century (modulo 400) from year, month, day of week, day of month
- New parameter -S to set the system time
- Improvements to DST handling
- Set error state if day of month is too large, not just when greater than 31
readpin:
- New parameter -t for readpin to adjust nanosleep() delay
- Determine realfreq dynamically, do not use realfreq from config.txt
general:
- Documentation updates
- Code cleanups
- New algorithm to receive bits from the radio signal from an idea by
Udo Klein, with permission [1] (configuration file changed)
- Use two independent maximum values for 0 and 1 bits (configuration
file changed)
- New verbose display output
- Weaken precondition for processing leap seconds and DST changes to not
insist on correct values for parity bits and bit 0, 20, 17, 18
- README.md updated
- Style and other minor fixes
* Simplify PORTDOCS installation

- better detection for bits in the radio signal
- catch more corner cases in decoding of the time data
The configuration file (hardware.txt) needs to be updated with this update.
platform but might work on other devices using GPIO pins too.
The received data can be logged for later playback/analysis.
