New version of Exiv2, a library and a tool to process Exif, IPTC and XMP metadata, is out with fixes and support for more file formats.

Changes, including those from 0.18.1 (April 2009):

• added writing to PSD (Adobe Photoshop);
• added reading of Panasonic RW2;
• updated Nikon and Minolta lens databases;
• fixed PNG and some kinds of NEF writing errors;
• fixed writing comments to JPEG;
• less visible improvements and bugfixes.

As usual, source code and a build for Windows is available for downloading.
