From f7d5c7d505c20273cd582ecb7e503266a31e6d0f Mon Sep 17 00:00:00 2001
From: ZZ-Cat <nicad.heli.flier@gmail.com>
Date: Mon, 1 Jul 2024 09:49:58 +1200
Subject: [PATCH 025/109] chore(library): Bump verion date to 2024-7-2

Setting the version date to tomorrow's date, because that's when I'm picking development up on CRSF for Arduino again... after a nealry two-month long quiet hiatus.

Subject: [PATCH 042/109] refactor(serial transmitter prototype): :recycle:
 Improve error handling

Instead of spamming the time delta in the Terminal, a simple notification is sent; and the prototyp test now halts when the `time_us_max_allowed_error` is exceeded.

From f1fe711ded576d742dec202ee1a0eb4472468626 Mon Sep 17 00:00:00 2001
From: ZZ-Cat <nicad.heli.flier@gmail.com>
Date: Mon, 1 Jul 2024 09:49:58 +1200
Subject: [PATCH 049/109] chore(library): Bump verion date to 2024-7-2

Setting the version date to tomorrow's date, because that's when I'm picking development up on CRSF for Arduino again... after a nealry two-month long quiet hiatus.

Subject: [PATCH 053/109] feat(serial receiver interface): :sparkles: Introduce
 three new callbacks (#134)

Three new callback functions are added to the Serial Receiver Interface:

- `onLinkDownCallback`
   Runs when no CRSF data is received within `CRSF_FAILSAFE_STAGE1_MS` (default is 300 milliseconds), and this may be used to facilitate fail-safe conditions.
- `onLinkUpCallback`
   Runs when a reconnection is established, and this may be used to facilitate fail-safe recovery.
- `onRawDataCallback`
   Runs whenever individual bytes from the raw CRSF data stream is received, and this may be used to facilitate UART pass-through.
