Each fix is listed with the version date that the device shows for about two seconds when it starts. Devices flashed before 2026-10-09 show no version. Reflash them to start from the first versioned build.

• 2026-10-09 — T-Watch S3 and T-Embed: the firmware version is shown at start-up.
• 2026-10-08 — T-Embed: flashes without holding the BOOT button again. The USB keyboard now starts on the first shake instead of at power-up.
• 2026-10-06 — T-Watch S3: the watch confirms that each shake reached the T-Embed, and shows NO LINK when it did not.
• 2026-10-06 — T-Watch S3: the radio settle delay is 10 ms instead of 100 ms, so a shake reaches the keyboard about 90 ms sooner.
• 2026-09-08 — T-Watch S3: fixed a boot loop caused by the audio driver. The watch has no audio.
