Release 2.2.0

* Add missing definition for default device callbacks (which prevents calling the `setDeviceCallbacks` method)
* Ensure `m_pDeviceCallbacks` inital value is set to `&defaultDeviceCallbacks` to prevent crash when pairing table is full

After #295 any time the pairing table fills up, the device will crash on the next pairing attempt.

 All notable changes to this project will be documented in this file.
-## [Unreleased]
+
+## [2.2.0] 2025-02-24
+
+## Added
+- Conditional macros for logging.
+- `NimBLEDevicecallbacks` class with a callback for handling bond storage.
+
+## [2.1.1] 2025-01-26
+
+## Fixed
+- remote descriptor discovery error when no descriptors exist.
+- scan filter settings not enabled for esp32s3/c3.
+- remote descriptor discovery returning more than the desired descriptor.
+
+## [2.1.0] 2025-01-12
+
+## Fixed
+- Crash when retrieving descriptors if more than one exists.
+- Incorrect TX power value being advertised.
+- New user guide code for 2.x
+- Potential race condition if `NimBLEScan::clearResults1 is called from multiple tasks.
+
+## Changed
+- If privacy is not enabled identity keys will not be shared.
+- `NimBLEDevice::setPower` and `NimBLEDevice::getPower` now take an additional parameter `NimBLETxPowerType` to set/get the power level for different operations.
+
+## Added
+- Config option `CONFIG_NIMBLE_CPP_ADDR_FMT_EXCLUDE_DELIMITER`, if defined will remove the ":" delimiter from the BLE address string.
+- Config option `CONFIG_NIMBLE_CPP_ADDR_FMT_UPPERCASE` if defined will make the BLE address strings uppercase.
+
+## [2.0.3] 2025-01-05
+
+## Fixed
+- Unused variable warning when log level is below info.
+- Build error missing definition of CONFIG_NIMBLE_CPP_FREERTOS_TASK_BLOCK_BIT in platformio.
+- Race condition in `NimBLEScan` that can cause a crash due to heap corruption if `NimBLEScan::stop` is called from the `onResult` callback.
+- Advertisement data not set if scan response is enabled after the data is set.
+- `NimBLECharacteristic`/`NimBLEDescriptor` not able to update their values in the `onRead` callback.
+- Too short of a timeout being requested in NimBLE_Server example leading to frequent disconnects.
+
+## Changed
+- `NimBLEHIDDevice` now allows for the same report ID in multiple input/output/feature reports.
+
+## Added
+- Config for custom log colors pre level.
+- Error logs in the case that NIMBLE_CPP_DEBUG_ASSERT is not defined.
+- Error logs when setting advertisement data fails.
+- Missing documentation in the migration guide about enabling automatic advertising on disconnect, which was disabled by default in 2.x.
+
+## [2.0.2] 2024-12-21
+
+## Fixed
+- Compile error when only advertising role is enabled.
+- Possible crash if bonded client reconnects.
+
+## Changed
+- `NimBLEHIDDevice` can now create more than one in/out/feature report map.
+
+## [2.0.1] 2024-12-16
+
+## Fixed
+- `NimBLEHIDDevice::getOutputReport` will now return the correct characteristic.
+- Compile error when central is disabled, class `NimBLEServer` has no member named `m_pClient`.
+
+## Changed
+- Added missing includes for `NimBLEConnInfo` and `NimBLEUtils` to `NimBLEDevice.h`.
+
+## [2.0.0] 2024-12-14
 
 ## **Breaking changes**
 - All connection oriented callbacks now receive a reference to `NimBLEConnInfo`, the `ble_gap_conn_desc` has also been replace with `NimBLEConnInfo` in the functions that received it.
@@ -60,6 +126,7 @@ All notable changes to this project will be documented in this file.
 - `NimBLEService::getCharacteristics` now returns a `const std::vector<NimBLECharacteristic*>&` instead of std::vector<NimBLECharacteristic *>.
 - `NimBLEUUID::getNative` method replaced with `NimBLEUUID::getBase` which returns a read-only pointer to the underlying `ble_uuid_t` struct.
 - `NimBLEUUID`; `msbFirst` parameter has been removed from constructor, caller should reverse the data first or call the new `reverseByteOrder` method after.
+- `NimBLEAddress` constructor; default value for the `type` parameter removed, caller should know the address type and specify it.
 - `NimBLEAddress::getNative` replaced with `NimBLEAddress::getBase` and now returns a pointer to `const ble_addr_t` instead of a pointer to the address value.
 - `NimBLEAddress::equals` method and `NimBLEAddress::== operator` will now also test if the address types are the same.
 - `NimBLEUtils::dumpGapEvent` function removed.

 This is a C++ BLE library for the ESP32 that uses the NimBLE host stack instead of bluedroid.  
 The aim is to maintain, as much as reasonable, the original bluedroid C++ & Arduino BLE API by while adding new features  
 and making improvements in performance, resource use, and stability.
