 # Changelog
 All notable changes to this project are documented in this file.
 
+## [1.7.2] - 2019-07-25
+### Added
+- Added functions in the DPPI, GPIOTE, PPI, RTC, and TIMER HALs for getting tasks and events specified by index.
+- Added the possibility of suspending transfers in the TWI driver. This allows combining several transfers into one continuous TWI transaction.
+- Added termination of transfers at deinitialization of the UARTE driver.
+- Added buffer alignment checks in the QSPI driver.
+- Introduced the NRFX_OFFSETOF macro that duplicates the functionality of the built-in offsetof() mechanism, but can be used without issues also with non-constant expressions.
+- Added an alternative way of ending the DMA transfer loop in the USBD driver.
+- Added the CTSTARTED and CTSTOPPED events to the CLOCK HAL.
+
+### Changed
+- Removed an assertion that prevented setting the data payload size of isochronous endpoints to zero, to fulfill requirements of the USB 2.0 specification, paragraph 5.6.3.
+- Declared the tx_buffer_length field in the UART driver's control block as volatile to prevent issues in case of compilation with high optimization level.
+
+### Fixed
+- Fixed an incorrect conversion of frequency values in the RADIO HAL.
+- Fixed an incorrectly enabled interrupt in the QSPI driver.
+- Corrected the LFCLK source selection values in the template configuration file for nRF9160.
+- Fixed support for external LFCLK sources for nRF52811.
+
+## [1.7.1] - 2019-04-08
+### Added
+- Added functions in the NVMC driver for getting the flash page size, the count of pages and the total flash size.
+
+### Fixed
+- Fixed handling of short unaligned write requests (1 or 2 bytes in length) in the nrfx_nvmc_bytes_write() function.
+
+## [1.7.0] - 2019-03-29
+### Added
+- Added drivers for NVMC and TEMP.
+- Added HALs: AAR and FICR.
+- Added support for the custom instruction long frame mode in the QSPI driver.
+
+### Changed
+- Reworked HAL for NVMC. Now it can be used for all SoCs supported by nrfx.
+- Reworked HAL for TEMP.
+- Improved documentation. Now it is more precise and can be generated without warnings with newer versions of doxygen.
+- Improved the UARTE driver to consume less current after the TX operation. Now at the end of the transmission the transmitter is turned off by the STOPTX task.
+- Improved C++ support in drivers. Now fields in structures are filled up in the correct order.
+- Changed to size_t the type used for holding the amount of data in the TWIS driver.
+
+### Fixed
+- Fixed a race condition in the USBD driver. It could occur when an IN transfer was interrupted by an OUT transaction, which in turn was interrupted by a process with a higher priority.
+
 ## [1.6.2] - 2019-02-12
 ### Added
 - Added the possibility to use the macro NRFX_COREDEP_DELAY_US_LOOP_CYCLES to specify the number of cycles consumed by one iteration of the internal loop in the function nrfx_coredep_delay_us().
