Set a time for scan responses so that callbacks are triggered.

* General code cleanup
* `NimBLEScan::start` will no longer clear cache or results if scanning is already in progress.
* `NimBLEScan::clearResults` will now reset the vector capacity to 0.
* `NimBLEScan::stop` will no longer call the `onScanEnd` callback as the caller should know its been stopped when this is called.
* `NimBLEScan::clearDuplicateCache` has been removed as it was problematic and only for the esp32. Stop and start the scanner for the same effect.
* `NimBLEScan::start` takes a new bool parameter `restart`, default `true`, that will restart an already in progress scan and clear the duplicate filter so all devices will be discovered again.
* Scan response data that is received without advertisement first will now create the device and send a callback.

 # Changelog
 
 All notable changes to this project will be documented in this file.
+## [Unreleased]
+
+### Changed
+- NimBLESecurity class removed.
+
+### Added
+- `NimBLEDevice::setDeviceName` to change the device name after initialization.
+- `NimBLEHIDDevice::batteryLevel` returns the HID device battery level characteristic.
+
+## [1.4.0] - 2022-07-31
+
+### Fixed
+- Fixed missing data from long notification values.
+- Fixed NimbleCharacteristicCallbacks::onRead not being called when a non-long read command is received.
+- Prevent a potential crash when retrieving characteristics from a service if the result was successful but no characteristics found.
+- logs/typos.
+
+### Changed
+- AD flags are no longer set in the advertisements of non-connectable beacons, freeing up 3 bytes of advertisement room.
+- Save resources when retrieving descriptors if the characteristic handle is the same as the end handle (no descriptors).
+- Subscribing to characteristic notifications/indications will now always use write with response, as per BLE specifications.
+- `NimBLEClient::discoverAttributes` now returns a bool value to indicate success/failure.
+- Scan result callbacks are no longer called when the scan response data is updated in order to reduce duplicates.
+
+### Added
+- Preliminary support for non-esp devices, NRF51 and NRF52 devices supported with [n-able arduino core](https://github.com/h2zero/n-able-Arduino)
+- Alias added for  `NimBLEServerCallbacks::onMTUChange` to `onMtuChanged` in order to support porting code from original library.
+- `NimBLEAttValue` Class added to reduce and control RAM footprint of characteristic/descriptor values and support conversions from Arduino Strings and many other data types.
+- Bluetooth 5 extended advertising support for capable devices. CODED Phy, 2M Phy, extended advertising data, and multi-advertising are supported, periodic advertising will be implemented in the future.
+
+## [1.3.3] - 2022-02-15
+
+### Changed
+- If attribute retrieval fails with a "not found" try again with the 16 bit version if a 128 bit base uuid is used.
+
+### Fixed
+- Memory leak when deleting client instance.
+- IDf version check for data length extension.
+- Memory leak when server services changed.
+- Compiler warnings for non-esp32 devices.
+
+## [1.3.2] - 2022-01-15
+
+### Fixed
+- Initialize advertising complete callback in NimBLEAdvertising constructor.
+- Clear client disconnect timer in constructor before initializing.
+- Fix missing data when reading large values.
+- Fix missing data in notifications when using a large MTU size and more than 270 bytes of data are sent.
+- Workaround fix added for cases when the task notification value is not cleared, causing various functions that should block not to block.
+
+### Added
+- `NimBLEClient::getLastError` : Gets the error code of the last function call that produces a return code from the stack.
+- `NimBLECharacteristic::notify` : Overload method to send notifications/indications with custom values.
+- Added conditional checks for ESP32 specific functions/values to support use of the library on non-esp32 devices.
+- Added an alias to use the callback name from the original library `onMtuChanged`.
+- `NimBLEClient::setDataLen` and `NimBLEServer::setDataLen`:  Data length extension support (IDF version >= 4.3.2 only)
+- Config option to set logging level for esp-nimble-cpp
+
+### Changed
+- Critical section calls now use the NimBLE API instead of FreeRTOS directly. This removes the need for a `portMUX_TYPE` variable in the class definitions.
+- Removed unnecessary variables in `NimBLEService` and changed the constructor no no longer accept `numHandles` and `inst_id` parameters.
+
+## [1.3.1] - 2021-08-04
+
+### Fixed
+- Corrected a compiler/linker error when an application or a library uses bluetooth classic due to the redefinition of `btInUse`.
+
+## [1.3.0] - 2021-08-02
+
+### Added
+- `NimBLECharacteristic::removeDescriptor`: Dynamically remove a descriptor from a characterisic. Takes effect after all connections are closed and sends a service changed indication.
+- `NimBLEService::removeCharacteristic`: Dynamically remove a characteristic from a service. Takes effect after all connections are closed and sends a service changed indication
+- `NimBLEServerCallbacks::onMTUChange`: This is callback is called when the MTU is updated after connection with a client.
+- ESP32C3 support
+
+- Whitelist API:
+  - `NimBLEDevice::whiteListAdd`: Add a device to the whitelist.
+  - `NimBLEDevice::whiteListRemove`: Remove a device from the whitelist.
+  - `NimBLEDevice::onWhiteList`: Check if the device is on the whitelist.
+  - `NimBLEDevice::getWhiteListCount`: Gets the size of the whitelist
+  - `NimBLEDevice::getWhiteListAddress`: Get the address of a device on the whitelist by index value.
+
+- Bond management API:
+  - `NimBLEDevice::getNumBonds`: Gets the number of bonds stored.
+  - `NimBLEDevice::isBonded`: Checks if the device is bonded.
+  - `NimBLEDevice::deleteAllBonds`: Deletes all bonds.
+  - `NimBLEDevice::getBondedAddress`: Gets the address of a bonded device by the index value.
+
+- `NimBLECharacteristic::getCallbacks` to retrieve the current callback handler.
+- Connection Information class: `NimBLEConnInfo`.
+- `NimBLEScan::clearDuplicateCache`: This can be used to reset the cache of advertised devices so they will be immediately discovered again.
+
+### Changed
+- FreeRTOS files have been removed as they are not used by the library.
+- Services, characteristics and descriptors can now be created statically and added after.
+- Excess logging and some asserts removed.
+- Use ESP_LOGx macros to enable using local log level filtering.
+
+### Fixed
+- `NimBLECharacteristicCallbacks::onSubscribe` Is now called after the connection is added to the vector.
+- Corrected bonding failure when reinitializing the BLE stack.
+- Writing to a characterisic with a std::string value now correctly writes values with null characters.
+- Retrieving remote descriptors now uses the characterisic end handle correctly.
+- Missing data in long writes to remote descriptors.
+- Hanging on task notification when sending an indication from the characteristic callback.
+- BLE controller memory could be released when using Arduino as a component.
+- Complile errors with NimBLE release 1.3.0.

+
+## About extended advertising
+Extended advertising allows for much more capability and flexibility.
+
+* Allows for 251 bytes of advertisement data and up to 1650 bytes when chained (configuration dependant) vs 31.
+
+* New PHY's (physical layers) that allow for faster data rate (2M PHY) or long range/slower data rates (CODED PHY) as well as the original 1M PHY.
+
+* New periodic advertising, allowing the scanning device to sync with the advertisements of a beacon. This allows for the scanning device to sleep or perform other tasks before the next expected advertisement is sent, preserving cpu cycles and power (To be implemented).  
+<br/>
+
+## Enabling extended advertising
+Extended advertising is supported when enabled with the config option `CONFIG_BT_NIMBLE_EXT_ADV` set to a value of 1. This is done in menuconfig under `Component config > Bluetooth > NimBLE options > Enable extended advertising`, or set in `nimconfig.h` for Arduino, or in `build_flags` in PlatformIO.
+
+When enabled the following will occur:
+* `NimBLEScan::start` method will scan on both the 1M PHY and the coded PHY standards automatically.
+
+* `NimBLEClient::connect` will use the primary PHY the device is listening on, unless specified (see below).
+
+* `NimBLEClient::setConnectPhy` becomes available to specify the PHY's to connect with (default is all).
+
+* `NimBLEAdvertising` is no longer available for use and is replaced by `NimBLEExtAdvertising`. `NimBLEDevice::getAdvertising` will now return an instance of `NimBLEExtAdvertising`.
+
+* `NimBLEAdvertisementData` is no longer available for use and is replaced by `NimBLEExtAdvertisement`. This new class is where everything about the advertisement is configured, including the advertisement intervals and advertisement ended callback.
