Peek-a-Boo 2.9.2

  • Stability fixes.

Peek-a-Boo 2.9.1

  • Several minor documentation fixes.
  • Some minor user-interface cleanup.

Peek-a-Boo 2.8.5

  • Improvements in Process Throb for the “speed” of 64-bit processes.
  • Increasing stability and better internal handling of the list of processes.
  • Some clarifications in filenames and descriptions of UI features.

  • The Process List window has had minor cosmetic updates.
  • Log file bug fix: no more spurious negative numbers.
  • Other minor bug fixes and updates.

Peek-a-Boo 2.8

Snow Leopard (Mac OS X 10.6) was the catalyst for a number of enhancements in Peek-a-Boo 2.8.
  • Many processes in Snow Leopard run in 64-bit mode (on supported machines), so 64-bit processes are now detected.
  • Memory usage of processes, especially that of 64-bit processes, is now tracked more accurately.
  • The Process Throb window works better with 64-bit processes.
  • Snow Leopard has changed some of the underpinnings of process management; Peek-a-Boo 2.8 has been updated to work properly with these system changes.

Peek-a-Boo 2.7.11

  • Improved crash reporting. (We hope crashes are rare, but if they do happen we would like to hear about them.)
  • Miscellaneous minor usability enhancements

Peek-a-Boo 2.7.10

  • Underlying architectural enhancements should increase stability.

Peek-a-Boo 2.7.9

  • Process Throb icons can now be customized so their size can correspond either to the process CPU usage or the process memory usage. (The Process Throb icon velocity then corresponds to the other attribute.)
  • Miscellaneous bug fixes.

Peek-a-Boo 2.7.8

  • Stability fixes
  • Minor bug fixes and enhancements

Peek-a-Boo 2.7.7

  • Tool tip enhancements
  • Minor performance improvements

  • Minor Leopard-related fixes.
  • Minor System Information Window fixes.

Peek-a-Boo 2.7.1

  • Each Process Throb icon’s velocity is based on the virtual memory it uses. This makes memory-intensive processes more obvious since they are moving more quickly.
  • Miscellaneous bug fixes and enhancements.

Peek-a-Boo 2.7

  • Peek-a-Boo 2.7 windows now look more consistent.
  • Several Leopard-related refinements.
  • The memory column in the process list window can now be sorted by physical memory in addition to virtual memory; see the preferences pane to set this.
