R-Studio 8.11 build 175479
New features:
- Automatic recognition and assembly of complex disk manager objects whose components are also various disk manager objects. This may be useful for data recovery from various NAS devices
- Updated Windows driver that can mount R-Drive Image type (.rdr) images of hard drives, besides logical disks, as virtual hard drives in the system

Improvements:
- The Open folder when done option has been added to the Recover dialog box
- File enumeration speed has been increased by several dozen times for Ext2/3/4 and UFS1/UFS2 partitions
- Folder scan to improve folder tree reconstruction on recognized Ext2/3/4 and UFS1/UFS2 partitions
- Ext4fs extent reconstruction for large deleted files even if they are not in the file system journal
- Network data recovery speed has been increased by several dozen times

Bug-fixes:
- R-Studio may have opened some partitions with large numbers of files for a long time
- The path selection dialog box may have frozen if some network drives were connected to the system under a user account
- R-Studio may have crashed during performing recheck recovery chances
- Volume labels may have been detected incorrectly for UFS1 partitions
- Idle RAID sequences may have appeared when a custom RAID was created. Those sequences could not be deleted
- When an invalid RAID table was applied, the program didn't throw a warning
- An incorrect minimum number of RAID table lines may have appeared for RAID0 and RAID4
- The cursor may have moved incorrectly when editing the RAID table
- Unit fields (TB, GB, MB) in the RAID editor may have worked incorrectly
- The Refresh DDI command may have appeared even when the DDI device was not connected

R-Studio 8.10 Build 173987
Improvements:
- LVM processing has been improved

Bugfixes:
- Empty sequences were generated in the Sequences window when the Custom RAID type was selected. Those sequences could not be deleted
- The last valid RAID block order table was saved rather than the current invalid table
- The Get Info window showed wrong file info when sorting had been changed
- Clicking an empty space on the Get Info window opened Hexadecimal editor
- Files remained marked when files were recovered with the Do not recover duplicate files from Extra Found Files option enabled
- Not all information on Overlapping files and Regions when saving file names
- The Find/Mark dialog box didn't preserve selections for the Look At Files/Folders option
- A file and folder may have the same ID on the time/extension sorting tabs. Clicking such object may have resulted in jumping to another object with the same ID. For example, to a file with an ID randomly coinciding with the ID of a folder
- Saving file names for marked files didn't save names for files with links in their paths. Only link name was saved without files in the related folder
- Some small interface and cosmetic bugs have been fixed
