Update: The final version of Mendeley Desktop 1.0 is now available from the downloads page or via the in-client auto-update from Mendeley Desktop 0.9.9 and later. Thank-you to everyone who helped test this release.
A preview of Mendeley Desktop 1.0 is available for testing on Windows, Mac and Linux. The preview can be downloaded from the bottom of the Mendeley Desktop downloads page. Before trying out this preview, please read the compatibility notes at the bottom of this post.
In this update, we have implemented some of the improvements most frequently requested by users in support emails and from our feedback forum.
We appreciate your feedback on this preview. You can leave comments on this blog post or in our feedback forum.
Find and Merge Duplicate Documents
- Mendeley Desktop now has a tool which you can use to tidy up your library and merge duplicate documents. To find duplicates in your library, go to Tools -> Check for Duplicates. Mendeley will then search through your library and present a list of duplicates that it finds, along with an indicator of how confident Mendeley is that a set of documents really are duplicates.

Sub-folders and Folders in groups
- You can now organize your folders in a hierarchy. To create a sub-folder, right click on a Folder and select ‘New Sub-Folder’.
- Folders can now be used in groups.

PDF Viewer
- The PDF viewer now remembers your last position and zoom/rotation settings when you close a tab and will restore them when re-opening a paper.
- The notes list has been re-designed. Notes now resize to fit their content and website addresses are now auto-converted to clickable links.
- Viewing annotations across groups is now easier. When viewing a PDF from one group, any notes or highlights added to the same paper in other groups you are currently a member of will also be shown.

File Organizer
- The file organizer now archives files in a separate folder when the corresponding document is removed from Mendeley Desktop, reducing clutter in your file organizer folder. There is also a Tidy Up tool in the file organizer preferences dialog to help you clean up existing organizer folders.
- File organizer settings are now saved in your local database, so multiple users sharing the same login on a PC can have separate file organizer directories.
Microsoft Word and OpenOffice Plugins
- The Microsoft Word plugin for Windows has a new look in Word 2007 and Word 2010, taking advantage of the extra space available in the ribbon.
- Search in the citation editor is now incremental, rather than only updating when whole keywords are entered.
- The Word and OpenOffice plugins now store a mini-library of cited publications inside your documents. When updating a Word document, Mendeley Desktop can import citations from the Word document back into your Mendeley library if necessary (for example, if you cited a publication which has subsequently been removed from your library).
- Various improvements have been made to citation formatting


Platform-Specific Improvements
- Windows: A number of stability problems with the Microsoft Word plugin have been fixed.
- Windows: The Mendeley Desktop installer and updater are now signed by Mendeley Ltd.
- Mac: The window size no longer expands when many tabs are opened.
- Mac: A number of Mac-specific crashes which occurred when importing or viewing certain PDFs have been fixed.
- Linux: It is now easier to get Mendeley running on Fedora. Mendeley also integrates better with the system look and feel.
Supported Platforms
Mendeley Desktop 1.0 requires Windows XP or newer on Windows, OS X 10.5 (Leopard) on an Intel Mac and Debian Lenny (or equivalent) and newer on Linux. Macs running OS X 10.4 or PowerPC are no longer supported.
Backwards Compatibility
When Mendeley Desktop 1.0 is run, it will automatically backup your existing database and then upgrade it. The backup will be saved to the archive directory in your Mendeley data folder. If you wish to go back to an earlier version of Mendeley Desktop, you will need to either:
- Copy your database from the archive directory into the main Mendeley data folder
- Delete your local database and let Mendeley restore your data from the web
The file organizer settings are saved in your local database in Mendeley Desktop 1.0 and are not visible to earlier versions of Mendeley, which stored file organizer settings in a separate file or the registry on Windows.
Microsoft Word and OpenOffice.org Compatibility
Mendeley Desktop 1.0 can edit and update citations and bibliographies in Microsoft Word and OpenOffice.org documents that were originally created by earlier versions of Mendeley. However, earlier versions of Mendeley Desktop will not be able to update citations or bibliographies created with Mendeley Desktop 1.0. This is a consequence of implementing the ‘travelling library’ feature and fixing a long-standing bug with the field types used for Mendeley’s citation and bibliography entries.
