Hi Tracker users,

Tracker 4.94 installers for Windows, Mac and Linux are now available from both the Tracker home page (http://physlets.org/tracker/) and ComPADRE (http://www.opensourcephysics.org/items/detail.cfm?ID=7365).

Be sure to take a close look at "External Model" tracks (formerly "Data Tracks"), which enable you to import data automatically from spreadsheets and other modeling programs using the system clipboard. For more information, see the Tracker Video Modeling with Spreadsheets tutorial at http://www.opensourcephysics.org/items/detail.cfm?ID=14056.

Some other changes in this release are listed below. For a more complete list, see the Change Log at http://physlets.org/tracker/change_log.html

• A new Go To dialog lets you jump directly to a desired frame, step or time
• Setting custom number formats for fields and table columns is greatly improved
• You can now double-click a Tracker file (TRK or TRZ) to open it in Tracker on OSX
• TRZ files can now contain any file type associated with a default desktop application (e.g., spreadsheet files)

As always, please report any new bugs you discover directly to me. Thank you!

Doug
