FreeTRX v0.13.0 Pre-release

- Power-on indicator — when the display doesn't stay lit (any backlight mode
where the screen goes dark, including None), the green LED flashes for
100 ms every 3 s so it's obvious the radio is still switched on. The flash
pauses whenever the LEDs are already in use: while receiving, while
transmitting, and while muted (which flashes the red LED instead).

- Battery "Bars" display — a third battery status option in the top status
bar alongside % and V: a battery-shaped icon holding up to four
segments, each representing 25 % of charge, with the fill blinking when
the battery is low. Cycle the mode with ◀/▶ at Menu → Options → Display
Options → Battery. The "Bars" menu label is localised (German: Balken).

- CRT-style shut-off animation — when powering off, the current screen
collapses towards the middle (squeezed to a line, then a dot) like an old CRT
switching off, replacing the "Power Off" message. (Colour displays only.)

- Fix: the muted "M" indicator in the status bar overlapped the GPS text
when GPS was enabled. The header icon is removed; the muted state is shown by
the flashing red LED alone.

- SMS recipient from contacts — when composing a message, press GREEN in
the recipient field to pick the destination from your private-call DMR
contacts (or type a DMR ID manually and press DOWN to move to the text). - Contacts list shows everything — Menu → Contacts now lists all contact
types together under the title "Contacts" instead of defaulting to the group
filter; HASH still cycles the per-type filters (all / groups / private /
all-call).

- Pride theme — the status/header bar and the menu title bar are now painted
in the top rainbow-stripe colour so they blend into the background instead of
showing as white boxes.

FreeTRX v0.8.0 Pre-release
released this
2026-07-14 12:48:17 +00:00 | 17 commits to main since this release0.8.0
- Three new theme presets (Display Options → "Theme"): Red (black-on-red
day / red-on-black night); Neon 80s, an 80s-synthwave palette that maps
several neon colours (cyan, magenta, violet, green, yellow) across the
individual UI elements over a dark background; and Pride, which paints the
background as a rainbow pride flag with black text and white menu/header boxes
kept readable over the stripes. - Build: each build now prints a per-region memory-usage summary
(FLASH / RAM / CCMRAM used, size and free) so the remaining headroom is
visible after every build.

FreeTRX v0.7.1 Pre-release
released this
2026-07-13 15:32:26 +00:00 | 22 commits to main since this release0.7.1
- Fix: the radio crashed when navigating the Messages menu with voice
prompts enabled. Menu strings added after the voice-prompt pack was built map
to a table-of-contents slot that doesn't exist; the player read past the end
of the table. Such strings now play silence instead (also hardens the
pre-existing strings sitting at the end of the table).

FreeTRX v0.7.0 Pre-release
released this
2026-07-13 14:53:33 +00:00 | 25 commits to main since this release0.7.0
- DMR text messages (SMS) — full ETSI/Motorola-TMS-compatible messaging:
compose on the keypad (multi-tap, up to 160 characters), inbox and sent box
(8 messages each, persisted to flash across power cycles), 10 editable
quick-text templates, an incoming-message popup with chime and one-key
reply, and delivery confirmation (waits for the ETSI response PDU / ACK
with a resend prompt on timeout). Transmits in the Motorola TMS format
(UDP port 4007) understood by BrandMeister, hotspots and most OEM radios;
receives both TMS and the Anytone/"DMR standard" format (port 5016) and
answers delivery-report requests from other radios. Reachable from the
main menu ("Messages") or a long-press on GREEN in channel/VFO mode.
Options: "Wait for ACK" and "My ID only" (accept only messages addressed
to your own DMR ID). Voice PTT is locked out while a message transmits,
and hotspot mode is unaffected. - Removed the main-menu icons — the top-level menu entries are plain text again.

FreeTRX v0.6.0 Pre-release
released this
2026-07-13 08:04:01 +00:00 | 29 commits to main since this release0.6.0
- Theme presets — selectable on the radio in Display Options → "Theme":
Custom (CPS-editable, default), BASIC 80s (Commodore 64 blue/light-blue),
Terminal (green-on-black night / black-on-green day), and Vertexic
(orange, black-on-orange day / orange-on-black night). The choice is stored
in the codeplug custom-data area (migration-safe; defaults to Custom), and CPS
theme edits only ever change Custom. - Fix: green LED flickering between the red flashes while muted during a DMR
QSO. The DMR RX handler re-asserts the green LED as soon as it reads it off, racing
the main-loop mute clear; the green LED is now held off at the driver for the
whole mute (and released on un-mute), so only the red flash shows. screenshot.sh— a one-command wrapper around the OpenGD77 screen grabber
that auto-detects the serial port and sets up a self-contained Python venv
(pyserial + pillow) on first run. Saves toscreenshots/.
