iShowU HD & HD Pro 2.1.5*Beta* This is a test release. The latest stable is listed below.
2.1.5 (16 July 2010)
    Fixes
    • Fixed issue with camera discovery causing crash on startup.
    • Major Thumbnail Rewrite: Due to excessive instability with QuickTime, the thumbnailer has been removed an put into another process. This should fix the majority of crash issues.
    • Fixed issue where resizing the window while recording could sometimes cause the recording to stop (especially noticeable in 10.5).
    • Fixed bug in countdown timer that could cause a crash if you did a retake while counting down.
    • Further locking/hang fixes.
    • Undo now works for deleting watermarks.
    • Resolving issues related to the preview, switching between screens, and changing monitor configurations.
    • Fixed an issue cleaning up the preview when it's reset (could have caused a crash).
    • Fixed the Presets editor so it doesn't do "weird stuff" when duplicating presets, and renaming presets.
    • Additional safety and locking in Recording layers and Media Checkpointer.
    • Added additional safety to the MouseCompositor, addressing issues with changing mouse cursors in CS5 (again, I don't have CS5 so cannot test).
    • Placed additional locking around audio shutdown (hopefully fixes issues with MOTU devices - I don't have one so I can't verify).
    • Fixes to QuickLook under Snow Leopard.
    • Fixed issue in Disk Stage of Low CPU mode.
    • Fixed bug starting HD on 10.5.x systems that'd cause a failure upon startup.
    • Further locking fixes within audio, and some further tidy up's after thumbnailing.
    • Cleanups in the thumbnail renderer, lots of additional locking, much work around making capture lifecycle more robust.
    • Fixed lock conflict in Camera Compositor that could cause a crash.
    • Fixed possible crash upon startup (GetCodecList and detection of cameras were walking over each others toes).
    • Fixed a potential problem with media checkpointer (it was possible for it to crash - which might be the source of a couple of crashes recently).
    • Fixed bug in the SSL initialization that could cause a crash at startup.
    • Fixing registration system.
    • Further improvements to stability (fixing rare crash during start of recording).
    • Fixed a serious problem that could cause out of memory errors and bad recordings.
    • Fixed the problem where compressing would never end.
    • Fixed color correction for Low CPU recordings.
    • Fixed crash when recording directly over the top of a previous recording (while prompting for recording names) - also fixed a potential crash when checking storage preferences.
    • Fixed recording in mono, so that it works correctly with other (non QT) players and also when uploaded to YouTube.
    • Sound recording is now more resilient if the sound source is interrupted often (as can be the case with digital inputs). A side effect is that recording will be more resilient under wider load situations.
    • Fixed issue with audio where devices with different sample rates could result in glitches when recording.
    • Fixed problem that could cause a crash when stopping recording.
    Changes
    • You can now toggle on/off the preview window.
    • Implemented ability to mix audio into 2ch AAC before uploading to YouTube.
    • Undo is now working.
    • Readers of iCreate magazine can now use version 2.1.5 as well as version 2.1.4.
    • Drastically improved performance within the video bar (no longer crashes with 150+ recordings either) and fixed various selection problems.
    • A few missing localized resources were found and added.
    • A check is made for accelerated renderers before the app begins. This prevents needless an unhelpful crashes if you've no display connected.
    • There is now an option in preferences that disables "sleep" while Low CPU mode is compressing a video (so you can ensure your machine doesn't go to sleep while it's compressing, but does after it's done)
    • Added Undo functionality to the video bar when deleting videos. It'll now move them back from the trash if that is where they were put (or just put them back into the video bar, if you didn't move them to the trash).
    • Added Abort option to the status menu, and Edit menus. The dialog now no longer pops up if you are holding the shift key at the time you choose to abort (this mimics the behavior of iShowU v1).
    • Added option to edit the capture area to the Edit menu.
    • The Upload dialog now remembers it's state (title, description, keywords and last chosen category).
    • Updated the Russian localization.
    • *New* Italian localization!
iShowU HD & HD Pro 2.1.3
2.1.3 (14 January 2010)
    Fixes
    • Fixed a bug that could cause a crash on startup.
    • Fixed a possible registration problem (would prevent registration in some cases).
    • Fixes for blue/purple screen on some G5 machines.
    • HD (not HD Pro) now defaults to Low CPU mode off, and variable frame durations ON. This mirrors the behavior of iShowU v1.
    • Fixed a bug with "record application audio" that could cause delays (massive latency) in the audio.
iShowU HD & HD Pro 2.1.2
2.1.2 (30 November 2009)
    Fixes
    • Improved startup time.
    • Now responds to Delete (key, and menu item) in a sane manner. Delete with a watermark or camera selected, deletes the watermark or disables the camera. Delete with a recording selected, is the same as pressing the X button on it's top right.

    • Keyboard compositor no longer shows pause, stop or camera toggle shortcuts.
    • Soundflower updated to 1.5.1.
    • Added Howcast upload script.
    • Changed the way application shutdown operates again (this I've fixed the crash on quit bug this time).
    • You can now turn off the warning message re 'Enable support for assistive devices' in Universal Access (useful if you are not able to turn it on). See the Display Preferences.

    • Added an indicator in the timer window, showing when the camera is active.
    • Added some additional validation around output video size.
    • If you're using HD Pro, and you've not removed the example watermark, you'll be prompted when you record so that you have the chance to remove it before doing a long record without realizing that it's there.
    • Updated the YouTube and Blip.TV defaults.
    • Updated Russian, French, Japanese and Simplified Chinese localizations. Localizers: The advanced panel will now auto size it's width based on your translations (thanks to Michael Krekin, Roland Leroux, Koichi Matsumoto and He Yunxuan).

iShowU HD & HD Pro 2.1.0
2.1.0 (28 November 2008)
    Noteworthy changes
    • Upgrade note
       If you run this version you won't be able to use a previous version of iShowU HD without first making some changes. Please see this post for details.
    • Recording Recovery - Normally if you have a crash or other terminal event during recording your work is lost (and that's BAD). shinywhitebox humbly preset: recovery. Restart iShowU HD and it'll now recover as much of your movie as is possible.
    • Low CPU mode is now more efficient - up to 35% depending on the size of your recordings (larger recordings see a greater efficiency boost). This means up to 35% less CPU and around the same reduction in disk bandwidth per second.
    • New: Now upload to blip.tv
    • New Low CPU modes - Now you can replicate iShowU Classic functionality and have variable length durations for your video frames (this'll break Final Cut compatibility - but at least you get the choice now). This option is available in pro mode only.
    • Thank you to everyone who installed Smart Crash Reports and submitted reports.
    Fixes
    • Fixed recording at 29.97 fps. Now imports correctly into Final Cut.
    • Fixed crash that could occur (audio related) when shutting down.
    • Fix for potential crash situation between grabber and preview.
    • Fixed crash on startup if screen not accelerated.

    • Pause now ... pauses.
    • Upload scripts are now upgraded if necessary.
    • Fixed issues with HD (non Pro mode) when recording. Recording rate (fps) is now smoothly limited to what the compressor can achieve in realtime (since HD doesn't have a Low CPU mode). This results in movies that are considerably smoother than they were in previous versions (e.g: recording Google Earth).
    • All preset tooltips now have correct tooltips.
    • Now presents a warning dialog if an attempt to upgrade a persistent store fails.
    Changes

    • More presets for Final Cut (Apple Intermediate versions of the ProRes presets).
    • Various registration system updates.
    • Default preview rate set to 12 fps (reduces preview load while idle).
    • Fixes and enhancements to the audio recorder.
    • Updated instructions on the Capture area display (Return - confirm capture area).
    • Update the manual with information about recovery mode, and the new Low CPU mode options (Off, Auto, On).
