Download Sumatra PDF 2.5.2

Another update has been released for the version 2.5 of Sumatra PDF released earlier this month. This open source program allows viewing of various document formats, including PDF, chm, and DjVu. In addition, it can handle epub and mobi ebooks, and cbz and cbr comic books. Compared to Adobe Reader, it is very light and therefore also well suited for older computers. This update should improve memory usage when reading cbz and cbr files.

We’ve released another small update 2.5.2.

In this release we reduced the amount of memory used by comic book files and made few improvements to PDF rendering.
