New in YAAC 1.0 Beta 52 (Feb 6, 2015)

  • minor performance improvements.
  • improvement of stealth digipeater vicinity plotting, using special non-transmittable symbol ?# to identify a vicinity-plotted non-beaconing digipeater, and combining the reported positions of multiple stations using the digipeater to better locate the digi.
  • fix transmission of Objects, including properly handling permanent Objects and properly remembering the number of times an Object has already been transmitted for the next restart of YAAC.
  • use proper units for displaying wind speed and gusts, and rain numbers in all places where weather data is displayed.
  • fix reporting of repeater/monitoring frequency information in beacon and Object reports.
  • improve the state display of the message pause control on the map toolbar.
  • ensure that vicinity-plotted stealth digipeaters can be plotted on the map.
  • update and improve built-in documentation.
  • bombproof YAAC startup against hung ports.
  • make it easier to find keystore password dialog on the screen when YAAC needs to open the keystore.

New in YAAC 1.0 Beta 51 (Feb 6, 2015)

  • fix keystore opening for YAAC startup with a saved SSL-APRS-ISport.

  • add command-line option for opening keystore when running in non-GUI mode.
  • ensure that SSL and non-SSL APRS-IS port drivers are treated the same way for message transmission.
  • enable packet transmission through SSL-APRS-IS port driver.

New in YAAC 1.0 Beta 50 (Feb 6, 2015)

  • fix breakage caused by using per-port callsigns for locally-originated packets, including fixing inability to transmit locally created objects and items.
  • more minor performance optimizations.
  • refix signed message code to include the sending callsign in the signature computation, moving the signature generation until transmission time when the callsign is specified for multi-port deployments (actually, setting the originating callsign for locally-originated messages is now always delayed until transmission time to allow for possibly being a multi-port deployment, whether it actually is or not).
  • add GPS sentence type support for proper encoding of compressed-mode APRS positions. Also ensure compressed-mode position format is complete even if user chose not to send GPS velocity or altitude.
  • bombproof OpenTRAC protocol code against delayed setting of local callsign.
  • remove north-east bias of randomized vicinity plot positions.
  • allow specifying aliases (tactical names) for stations before you have actually heard them, and prevent purging knowledge of those alias assignments as long as they are still in force, even if the station no longer is transmitting.
  • correct storage of APRS Objects and Items to make case significant, even though case is not significant for stations (since all callsigns should be in uppercase, according to the AX.25 protocol specification). Note this doesn't yet support the extreme special case in the APRS protocol specification stating that Objects with the special permanent timestamp should be treated as unique objects if sent by different stations (unlike other Objects and Items, which can be taken over by other stations).
  • upon YAAC startup, the persisted Objects transmitted by that YAAC installation should have their first transmission time randomly spread out within the initial send rate interval for each Object, to prevent a huge transmit pile up at YAAC startup and every repeat interval thereafter for those persisted objects.
  • ensure that YAAC asks for the keystore password prior to attempting to transmit any message expecting signature computation at transmit time.
  • fix the column refreshing for the age columns in the Health Monitor view (these were broken when the alias columns were added before the age columns but the age refresh timer wasn't updated correspondingly).
  • prevent user from modifying port driver type of an existing port definition; the port type can only be specified when the port definition is added, and changing the type requires deleting the port and re-adding it with the new type. Add a warning to the generic port editor view telling the user why this is so to prevent complaints.
  • ensure the key import panel always confirms that the keystore password has been entered, to handle the case where the panel is launched from the SSL APRS-IS port editor instead from the key management view.
  • in the configuration wizard, when re-run on an already configured installation, ensure that the digipeater and I-gate capabilities are tested separately. Also automatically turn on tracing for WIDE1-1 digipeating, and ensure that both WIDEn-N and SSn-N aliases are properly enabled or disabled as the max-N spinners are adjusted.
  • fix fatal typo in OSM file importer's logging code.
  • generalize message signing logic so that key manager code doesn't have to contain message-type-specific signing code.
  • add initial draft of KISS-over-TCP port driver for TCP/IP-connected KISS TNCs.
