Developer TLA Systems has made many improvements to the iPhone version of its PCalc calculator application. Now it’s bringing many of those changes to the Mac version of the scientific calculator.

PCalc 3.5, released Thursday, adds new functions, including hyperbolic trig, hypotenuse, gamma, delta percentage, memory/stack clear, and last x. TLA has also added a “2nd” key to the application that shows additional functions. Other changes in PCalc 3.5 include multiple-memory support, optional HP48-style RPN behavior, key click sounds, and support for regions that use a quote as the thousands separator.
The upgrade is free for registered users of version 2 or 3 of PCalc. The calculator costs $19 and runs on Mac OS X 10.4.2 or later.—Philip Michaels Opera rolls out third beta for next browser

The new version includes performance and stability enhancements, improvements to the Opera Turbo compression tool, and refinements to the look and feel of the program.
In addition, the beta version offers options for where browser tabs are placed, allowing them to be on the right and left side of the screen as well as the top and bottom.
Also included are compatibility for 39 languages, a built-in crash logger, and better speed over slow network connections.
Media-cataloging software Delicious Library has been updated to version 2.2. The update, which is required for all users, implements a new requirement by Amazon for users to digitally sign requests for information.
