+ New extended duplicate file processing options.

Improvements:
* Improved support for the NTFS log.
* Extended recovery log.
* Improved data copying in Hexadecimal editor.
* A file path can be scrolled and copied in the "File already exists" dialog box.

Bugfixes:
- Data copy commands might work incorrectly on the Properties tab. Fixed.

- Several fixes in scanning and processing of recognized NTFS partitions.
- Some fixes in image creation of UFS partitions.
- Internal fixes and improvements.

R-Studio for Linux 4.0 build 2427 Tue Jul 12, 2016
New features:
+ Data recovery speed and results are improved by using a new data analyzing and recovery kernel.
+ Support for processing of the file system journal for HFS+ and Ext3/4fs partitions. That increased a number of successfully found files.
+ Support for processing of the soft updates journal to enhance data recovery from UFS partitions.
+ Support for recovery of extended attributes for HFS+, Ext3/4fs, and UFS file systems. That improves recovery of Mac OSX Time Machine and Linux selinux ACL.
+ Support for recovery of compressed files in HFS+ file system.
+ A symlink recovery options tab is added to the Settings dialog box in the Technician version.
Text/hexadecimal editor:
+ Search for Not equal string is added.

Improvements:
* Memory optimization for large disk scans.
* Faster Open Drive Files operation.
* Improved S.M.A.R.T. information monitoring. Different icons in the Drive View are used to show the overall HDD SMART status.
* Hard links, symbolic links, and their targets are shown using different icons.
* Scrollbars are added to the Scan Information and Parents tab.
* Improved discovery of the folder trees for deleted files on Ext3/4FS and UFS partitions.
* Created / modified / accessed time stamps on the Find/mark and Mask dialog boxes can be set separately.
* 4 digits are used for the Year field on the Find/Mark and Mask dialog boxes.
* A regular region can be turned into an exclusive one.
* An exclusive region can be of any size fitting the disk. Previously it could only be equal to the disk size.
* Some information, including drive names, file paths, names, etc., can be copied from R-Studio panels.
* Debug information can be saved not only in the fss format, but in the rdr format, too. This format includes all file system meta data, but much less in size when a compressed disk image.
* Text/hexadecimal editor: The status bar now shows the cursor offset in the decimal format, too. It can be copied directly from the status bar.
* A new forensic log file is created only when the computer configuration has been changed. The CaseName/Number/Operator info is written to the forensic log for each session.

Changes:
= The Metadata file types are made invisible on the Known File Types dialog boxes. They are data on a disk rather than actual files, and have no effect on the search for known file types.

+ Support for Windows Storage Spaces created by Windows 10. Now R-Studio can process WSS created by Windows 8/8.1 and 10, both with automatic recognition and manual adding their parents.
+ Support for Apple software RAIDs created by the OSX system. R-Studio can automatically recognize and assemble them from their members. Members with severe corrupted RAID parameter records can be added manually.

R-Studio for Linux 3.6.1466 Fri Oct 03, 2014
New features

+ Support for DiskSpare Disk Imager (DDI) images and disk maps. R-Studio can read and process images and disk maps created by standalone DDI hardware.

Improvements:
* When recovering data over network, R-Studio now processes virtual block RAIDs, as other objects, on the remote side, avoiding large data transfers over the network.
* R-Studio Demo can recover files up to 256 KB.
* The scanning stop procedure is improved: scan information can be saved before stopping.

Bugfixes:

They can be viewed, edited, imaged, copied to physical drives, etc. This technique also can re-construct data on the real parents of a virtual RAID, on a missing disk, for example.
+ S.M.A.R.T. attribute monitoring. R-Studio can display S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) attributes for hard drives to show their hardware health and predict their possible failures. Any unnecessary work with such hard drives should be avoided if S.M.A.R.T. warnings appear.

Improvements:
* Enhanced parity delay controls.

Bugfixes:
- Several connections from the same remote computer were possible. Fixed.
- R-Studio didn’t warn about losing informaiton on a virtual RAID upon its closure. Fixed.

R-Studio for Linux 2.0 Build 371 Jun 20, 2012
New features:
+ Simultaneous image creation and scan. Now R-Studio can create an image and simultaneously scan the data being copied. In this case R-Studio creates two files stored at the same place: an image file and file with the scan info.
+ File Recovery Lists: lists of files found on disks that can be exported out of R-Studio, manually edited, than imported back, and files from those lists will be automatically marked for recovery. Such lists are very useful if you want someone who is far away to decide which files are to recover and which aren’t to.
+ RAID consistency check: you may check whether the parity blocks on a RAID are valid.
+ Image and scan info files may be saved on and load from, remote computers. This helps R-Studio to avoid transferring large data volumes over network during network recovery.

Improvements:
* R-Studio processes HFS and FAT file systems much faster.
* R-Studio processes Known File Types much faster.

Bugfixes.
- Sometimes, R-Studio might crash during disk scan. Fixed.
- Some bugs in the Region and Exclusive Region dialog boxes are fixed.
- On the Find/Mark and File Mask dialog boxes, it was possible to enter inconsistent data interval into the between field. Fixed.

Improvements:
* The GUI language can be changed on-the-fly.
* Explicit specification of any IP address for incoming connections.
* R-Studio now deletes dot and space at the end of the names of recovered files and folders. Windows Explorer and many other programs cannot open such files. They can be opened only if they are opened using their URI (The full path started with //).

Bugfixes
- Some bugs for x64 architecture under modern releases. Fixed.
- Corrections in the French localization.
- Possible crashes during scan and opening of files.
- Search might not work is some parameters are entered into the Find/Mark dialog box. Fixed.

- Sometimes R-Studio could freeze while scanning. Fixed.
- Some bugs are fixed in the module loading Known File Types and RAID description files.
