h2zero/NimBLE-Arduino 2.4.0 on GitHub

Fixed

GATT attribute handles are now assigned from the registration callback so duplicate UUID attributes are identified correctly.
Dynamic service changes now properly remove characteristics/descriptors and reset the GATT database when advertising starts.
Missing notification/indication payload data when the value spans multiple mbufs, such as values larger than 255 bytes with small ACL buffers.
NimBLEDevice::createServer will longer crash when called before the stack is initialized.
Re-pairing after deleting all bonds now works by unpairing each stored bond instead of only deleting NVS data.
Whitelist bounds checks.
NimBLEDevice::getBondedAddress index bounds validation.
ESP32 linker error when both central and peripheral roles are disabled.
Compiler warnings when bonds are disabled.

NimBLEStream, NimBLEStreamClient, and NimBLEStreamServer classes and examples.
NimBLECppVersion.h with compile-time version macros.
NimBLEDevice::getVersion runtime version string helper.
Matching passkey callbacks for both roles: NimBLEServerCallbacks::onPassKeyEntry and NimBLEClientCallbacks::onPassKeyDisplay.
Bond migration helpers to convert bond storage between v1 and current formats while preserving existing bonds.
NimBLEUUID constructor overload for ble_uuid_t*.
Optional index parameter for NimBLECharacteristic::getDescriptorByUUID to access multiple descriptors with the same UUID.

NimBLEService::start is deprecated; services are now added when the server starts.
NimBLEHIDDevice::startServices() is deprecated; services are now added when the server starts.
