+### v4.0.0-rc.1 (2023-11-18)
+
+#### Behaviour changes
+
+* Opening a `GptDisk` now succeeds even if one header is invalid

+
+#### Changes
+
+* Bump MSRV to 1.63
+
+* Remove initialized state & configuration
+* add the option to allow the partition count to be changed
+* add the option to only open a disk if both headers are valid
+* add the option to keep the backup partition readonly
+* split `GptDisk::remove_partition` into two functions `remove_partition` and `remove_partition_by_guid`
+* add `GptDisk::header` function which allows to get the current header (either primary or backup)
+* add `GptDisk::take_partitions`
+* remove `GptDisk::update_partitions_safe` and replace it with a config option `readonly_backup`
+* remove `GptDisk::update_partitions_embedded` and replace it with the config option `change_partition_count`
+* add `GptDisk::device_ref`
+* add `GptDisk::device_mut`
+* crc32 are now stored in the header after it has been written instead of always being zeros
+* Add DragonFlyBSD as partition and OS type
