changes and updates include:
1. yet more improvements and bugfixes in OpenStreetMap importer, including
? ? support for coastline shapefiles and actually fixing tiling of large
? ? bodies of water, and adjusting default assumptions for incomplete OSM
? ? records to account for cases where the assumptions didn't apply (such
? ? as assuming a riverbank is a closed area of a section of the river
? ? [both banks] rather than potentially only one shoreline).
2. fix errors in the Maven pom.xml files provided for an alternate means
? ? of building YAAC. Note that the Ant build.xml files are still the
? ? supported means of building YAAC and its plugins.
3. clean up Javadocs and fill in more missing Javadocs.
4. eliminate incorrect identification of TCPXX as a digipeater alias.
5. more minor performance enhancements.
6. add ability to parse time intervals (Ages) as well as display them.
7. fix up display of the YAAC Help->About dialog, ensuring that it
? ? can't grow excessively large from installing many plugins and increasing
? ? the font size.
8. allow quad-sized icons so if all icons are displayed in double-size
? ? then more significant stations/objects can still be displayed in
? ? a larger size on the map.
9. fix displaying weather stations as old-style weather map symbols
? ? so that the temperature and dew point are in the configured
? ? temperature units instead of fixed at Fahrenheit.
10. fix beacon configuration to ensure any modified beacon record has
? ? ?the chance to be saved when switching to another beacon record,
? ? ?and ensure the controls for setting beacon-specific rates are
? ? ?properly set to the last values for that beacon instance instead
? ? ?of always to the APRS defaults. Also add sanity check to beacon
? ? ?free-text comment in case user puts the word EMERGENCY in the
? ? ?text, just to validate that they really want to announce a real
? ? ?emergency to listening stations.
11. fix configuration wizard to propagate callsign-SSID changes to
? ? ?existing ports rather than only to any new ones (which might not
? ? ?be created when the callsign is changed).
12. add to list of standard APRS-IS backbone rotator domain names, the
? ? ?CWOP rotator (which contains traffic from non-amateur-radio
? ? ?Citizen's Weather Observation Program stations)
13. for the WxNow.TXT port driver, supplement support for the 2-line
? ? ?Cumulus file format with chooseable support for the 1-line
? ? ?Weathercat (TNC2 command-mode frame) format, and allow freely
? ? ?typing the model code of the weather sensor as an alternative
? ? ?to the canned list of model codes.
14. add transmit slowdown to radio ports to try to ensure TNC has time
? ? ?to get the last packet out before pushing a new packet into the
? ? ?TNC, as some TNCs don't have the buffer space for more packets
? ? ?from the computer when the last one hasn't finished going to the
? ? ?radio yet. Was already there for Serial_TNC port type, added for
? ? ?other TNC port types.
15. update the list of referred websites for obtaining OpenStreetMap
? ? ?dataset downloads.
16. restructure the email composition method in the Telemetry Alarm
? ? ?plugin so it can be accessible from other plugins.
17. properly handle weather data in APRS packets when the field is
? ? ?provided but filled with "..." to indicate the sending station
? ? ?does not actually have that data parameter.
18. reduce JVM heap thrashing by replacing calls to
? ? ?StringBuilder.append(s.substring(start,end)) with
? ? ?StringBuilder.append(s, start, end).
19. add more support in core YAAC for inter-plugin data sharing.
20. eliminate spurious re-render of the OpenStreetMap layer just
? ? ?because a new station was heard.
21. refactor MADIS weather data quality check so it can be used
? ? ?elsewhere than just in the Health Monitor view, including in
? ? ?the new Weather Alert plugin (more about this later).
22. fix issue reported on APRSSIG mailing list 8 May 2020 about
? ? ?I-gating packets with embedded carriage return and line feed
? ? ?characters.
23. (provided by James Palmer AG5VQ) fix bugs in the CallsignDB
? ? ?plugin to support multiple licenses/callsigns per individual
? ? ?licensee.
24. fix duplicate speaking of the degree portion of a longitude
? ? ?in the sounds plugin.
25. add new Weather Alert plugin, which reports when certain conditions
? ? ?are detected in local or remote weather data, by verbal speech,
? ? ?email, SMS, highlighting the station on the map, and sending
? ? ?APRS text messages.
