See History for previous build notes.
New: Merge code by AI5QK adding TCP access to Green Heron rotators.
Change: Text Decode now hard-wraps at the right edge of the window. Existing content is never reformatted. Characters other than alphanumeric, space, and / are discarded.
Change: Handle CR and LF in decoded RTTY text by starting a new line in the Text Decode/Encode window.
New: Added UI to Voice Keyer Editor for setting the keyer watchdog timer timeout value. Thanks JH5GHM.
Fix: Info field prefill for contests with Age as part of the received exchange was current year for all calls instead of age from previous QSOs or exchange archive. Thanks W2RU.
The Color chooser used in Logging settings now limits choices to named colors in an effort to better support colors that adapt to either light or dark mode. Previous color choices in your settings file will be changed to a named color (if possible), when you first run this version or newer. If no match can be found the SkookumLogger default will be used. Review any custom colors you've set in Settings > Logging.
Change: Removed the modifications related to synthetic voice messages in the previous beta and started over. Added support for inserting arbitrary (non-voiced) characters between words in phoneticized strings; the effect is to modify the "quiet" duration between, for example, the words when sending a call sign. A hyphen shortens the duration and some other characters increase the duration. All of the text fields in the Voice Messages Editor window now apply edits on every keystroke, to make it easier to experiment with what happens with characters that are not voiced. Also, the settings are not per-radio. Thanks JH5GHM.
Change: Restored the Dark mode appearance of some titled boxes with thin borders, which was broken by Tahoe.
Fix: DVR message play with an IC-7300 was failing to inform SkookumLogger when the message ended. This fix likely applies to other ICOM radio. Thanks 2E1OTT.
Fix: The Rate Tracker window shifted down from its previous position when starting SkookumLogger. Thanks JH5GHM.New: On the first run of build build 40127 or newer, a one-time migration is performed to relocate SkookumLogger configuration files. This migration isn't necessary for New users that haven't run earlier versions. The Guide has more details on this in the Uninstalling or Moving SkookumLogger chapter.
Change: Notes entry field may now contain user text entered either before or after (or both) the part delimited by « and ». Thanks W2RU.
Change: Voice keyer supports per-radio settings, and adds a hidden preference for choosing a different character when voicing a space in messages. Thanks JH5GHM.
Fix: Was assigning skimmer spots from DXSpider for RTTY mode as CW mode. Thanks WA1Z, W6SX.
Fix: The Minipan window was displaying a wrong center frequency for a corner case just below xxxx.0 kHz.
Change: Tahoe was defeating SL use of entry field background colors to indicate status. Field borders and background color are now visible when field isn't focused. Thanks JH5GHM.
Fix: Rate Tracker wasn't displaying cumulative rates per band. Thanks JH5GHM.
Fix: Crash in practice mode. Thanks JH5GHM.
New: Support for IC-7760.
Fix: Call field background color was inconsistently changed when call exactly matched a known call. Thanks JH5GHM.
Fix: Inside QSO parties that use DXCC code for the DX exchange were being tagged as XQ. Thanks AI6W.
Fix: Checksheet status filter was being applied to all QSOs instead of obeying the area filter. Thanks AI7SK.
Fix: Enable UDP QSO broadcasting to LAN (different from WRTC2022). Thanks WA1Z.
Fix: SkookumNet would not open. Thanks WA1Z.
Change: Reenable QSO broadcasting scheme used in WRTC2022. Turn it on for WRTC2026 logs and off for all other logs.

Fix: Was pre-filling some calls outside YO with region codes in YO DX Contest.
Fix: Typo in KPA1500 TCP disconnect message. Thanks GØDVJ.
Fix (Maybe): The previous beta started up without opening any log file. If this beta starts up OK but doesn't open your previous log, try File > Open Log…
Change: The Guide has edits relating to a future build change involving where SL finds its preferences and support files.
Fix: Score was zero for WAEDC Inside. Thanks CT1DRB.
Fix: Was failing to include WAE countries as multipliers in WAEDC Outside. Thanks JH5GHM.
Fix: Was not displaying seeMe spots when DXCluster login call contained an SSID. Thanks AI6W.
Change: Force the XQ log column to always visible. Position the column left-most in the table each time you open a log file. Add a tooltip for the column referencing the Log > Explain ... command.
Change: Update the list of British Columbia districts for BC QSO Party. Thanks VA7BEC.
Fix: RSGB IOTA was flagging QSOs with World Stations as eXcluded because region code "-" wasn't recognized.
New: Great Circle Map with ITU Zones for WRTC 2026.
New: Display DXSpider seeMe spots as yellow dots on GCM maps. Use set/seeme to enable, unset/seeme to disable. Clears when list of seeMe spots radio changes band. Radio 1 only.
Improvement: Do not allow practice S&P stations to be created outside of ham bands.
Fix: IARU Society code for Austria changed from OEVSV to OV. Thanks W6FB.
Fix: The Practice Start/Stop button title didn't change to Start when a practice was stopped by reaching the "Disable after n successful QSOs" limit.

Change: The SQ column title is changed to XQ, for eXcluded QSO (AKA X-QSO).
Change: The default lower edge for the 160m phone subband is now 1900 kHz (was 1840) to stop generally unwanted mode changes from CW to SSB.

Fix: All Asian Contest Outside wasn't identifying zero-point QSOs.
Fix: Log > Reset Log wasn't reseting the internal exchange database containing records from the log being reset. Thanks W2RU.
Fix: Dragging the splitters in Panadapter windows and the DXCluster windows was doing nothing in Tahoe.
Fix: Crash when creating a Practice mode spot for a callsign longer than 9 characters.
Fix: Crash when a DX announcement was missing the colon or the colon appears beyond character 14 in the announcement.
Fix: Crash when clicking a Fonts and Colors color well in Logging Settings on Tahoe.
Fix: The passband extension into Panadapter Sub Receiver waterfall was not being hidden after frequency is stable for a bit.
Change: Help > DXSpider Spot Filtering now opens a W3BG/N3RD tutorial.
Change: Modified the default (new user) spot filter definition.
Change: Rewrote the Spot Filters section in the SL Guide.
Change: Increased the width of spot lines in Waterfall displays to increase visibility.

Change: Altered colors in Panadapter views to match K4 colors, except waterfalls are grayscale.
New: Lines in the DXCluster spot filter editor can be commented out by beginning them with '#'.
New: For General Logging, if you enter a valid Maidenhead grid in the QSO Info entry field, SkookumLogger sets the target point to that grid when you tab or spacebar out of the field.
