-# v0.6.1 (2022 July 2)
+# v0.6.2 (2022 August 13)
+
+## Overview
+
+This is a minor release that includes a few new features and memory efficiency-related changes that make echopype better.
+
+## New features
+- Add a new subpackage `consolidate` that contains functions to consolidate data across the calibrated Sv dataset and the corresponding raw-converted file
+- Add function `consolidate.add_location` to interpolate location to calibrated dataset (#749)
+- Add function `consolidate.add_depth` to convert `range_meter` to `depth` with information on transducer tilt and depth (#738)
+- Move function that swaps the channel with frequency dimension (now as `consolidate.swap_dims_channel_frequency`) (#738)
+- Add new functionality to allow control of logging outputs (#772)
+
+## Under the hood enhancements
+- Improve memory usage while converting files that require significant NaN-padding and previously would incur very large memory expansion (#774)
+  - This is achieved by directly writing variables that may incur a large memory expansion into a temporary zarr store
+  - Beta function that will benefit from user feedback
+- Overhaul access pattern for EchoData (#762)
+  - Remove previous access pattern for different groups in the raw-converted file
+  - Starting from this release all groups are accessed with `echodata["GROUP_PATH"]`, e.g., `echodata["Platform"]`, `echodata["Sonar/Beam_group1"]`, etc.
+- Make long_name in ds_power for EK80 consistent with other sonar model (#771)
+- Modify `set_beam()` so it returns a list (#780)
+- Change the order in `_save_groups_to_file` so the order of groups is preserved when opening a converted netcdf file (#779)
+- Remove the user option to select NMEA sentences in `open_raw` to ensure raw data is preserved (#778)
+
+## Infrastructure
+- Update CI set up to avoid exceeding GitHub actions memory limitation (#761)
+  - decrease the number of workers from 4 to 2
