Great news! Media Composer v8.9 has launched and is available on the Download Center (login and password required), Application Manager v17.7 and My Avid Master accounts for people with eligible contracts.

The ReadMe and Whats New Documents can be found at this link.  (IMO it is well worth checking out the Whats New Document)

Installer: There is a Media Composer v8.9 Mac and v8.9 Win Installer. No patch installers with this release.
- New Nvidia Driver: Nvidia Driver v377.11 is supported with this release.

Changed in v8.9: The following has been changed in this release.
- If you are on a Windows 10 or a Windows 7 system and have a Quadro 4000,K4000, or M4000 graphics card, DMF jobs might fail, background transcode and render jobs might fail, and you might see artifacts in the User Interface.

*** Workaround: On the Windows 10 system, install NVIDIA driver v342.01. On the Windows 7 system, install NVIDIA driver v377.11.

Fixed in v8.9: The following have been fixed in this release.
- When your locale was set to German, Spanish, or Italian, a number of Media Composer dialog boxes displayed cut off text. Avid has made improvements when displaying these languages so the text is displayed properly. Also, a number of dialogs now include tool tips in the appropriate language. Avid will continue to make improvements with subsequent releases.
- In previous releases certain DVCPro clips could not be linked. Now they can be linked.
- If you changed the tape name of a clip, the timecode changed by the number of pre-charge frames.
- Left Margin setting did not apply to a new script.
- When “Interpolate Position” was disabled in Script Settings, Scripts were still imported with Interpolate Position enabled.
- (Mac) When exporting EDL using “To several files,” V1 track files were not created.

- You might have received an “Assertion failed” error when trying to export an empty sequence to XDCam.
- (Mac) Performing a background render ignored Source Settings LUT. Fixed in Media Composer v8.9
- You might have corrupted output in the record monitor when you opened the Effect Editor of a rolling title.

- (Mac) The application would crash when opening Effect Mode on clips with a TV Noise Horiz effect.
- (Mac) The editing application would crash while opening Effect Mode of an Animated Marquee title.
- Importing two tracks increased the clip duration by 1 frame.
- Changing local clip colors did not save if that was the only change you made.
- In some instances after performing a match frame, shift clicking to select a range of clips in the bin did not select the clips.
- When an AudioSuite rendered effect was removed from the sequence, you could not close the plug-in window.
- (Japanese locale) Sequences with names that included a CR (carriage return) or LF (linefeed) displayed as offline in Interplay Access. With this release, newly created sequences will remove any CR or LF from the name. For older sequences, you can manually rename the sequence name to remove CR or LF.
- You might have received “Assertion Failed: minVBVLevel <= maxVBVLevel” errors when performing a mixdown of XDCAM media. Workaround: Enable the “Re-encode for XDCAM bitstream compliance” option in the Mixdown Video dialog.
- When in the Source Browser, linking to an XAVC Long GOP volume did not work properly. This has been fixed. The latest nablet-Sony XDCAM plug-in is required for XAVC Long GOP volume support.

Known Limitations: The following are known limitations in this release.

- When working with HiRes monitors, if you are in Frame View, playing back a thumbnail is not in the correct position while playing in bin.
- Occasionally, when working with media with effects or media where space, time or color adapters were rendered during transcode or video mixdown, you might see artifacts during playback or export. *** Workaround: Go to the Render Settings dialog and choose Disable GPU effects.
- While working in the Script Window, text operations (cut/copy/paste/delete/editing) can only be done in edit mode. See “Editing a Script” in the Help.
- When working with Panasonic LongG media, you might receive an “SFPlayConsumer Timeout” error if audio waveforms are enabled. *** Workaround: Turn off audio waveforms.
- Multicam editing with Panasonic LongG media is not supported with this release.
- Currently, when working with LongG media, you might see dropped frames when editing 4 streams. This might occur when playing from a single stream to multiple streams (and from multiple streams back to a single stream). The dropped frames usually display around the edit point (transition to a different stream).

I installed media composer 8.9 and app man 17.7 and my earilier problems seem to have returned

AppMan again says "Open" rather than "No Update" to the right of Media Composer 8.9.0

Is it still necessary to uninstall previous versions of MC (8.8.1)

Thanks, Wren

Yes

Unless you have a dual boot drive with 2 OS.  You must remove older versions to upgrade.

Just upgraded to 8.9.2 from 8.8.4 on a 5K Imac with OS 10.11.6 with a Black magic mini monitor (desktop video 10.9.7) . The new version works for about 2 hours and then hard locks up the system requiring a hard restart. Upon rebooting it gives errors that some of the last media written is corrupt and rebuilds the databases. 

Other software installed is the latest version of Baselight Editions, BCC 11, Magic Bullet Looks and Sapphire 11. 

I'm rolling back to 8.8.4 as it was very stable and did not hard lock up if it crashed.

Great news!  Media Composer v8.9.4 launched today, Monday, December 4, 2017 at 3:00 pm EDT.   

Location at Launch:  Media Composer v8.9.4 is available from My Avid Master Accounts, Application Manager, and the Avid Download Center (login and password required) @3:00 PM EDT.  

Installer:  There is a Media Composer v8.9.4 Mac and v8.9.4 Win Installer.    

Patch - There are NO Patch Installers. There are updates on the patch page, but they are full installers only there because some users only go to the editor patch folder to grab the latest build.

What’s New in v8.9.4: The following has been changed in this release.

• Support for HiRes Monitors with Mismatched Scaling - In previous releases, Media Composer supported dual HiRes or HiDPI monitors when both monitors were set to the same scaling. With this release, you can mix 100% and 200% scaling for Win10 dual monitor setups.
• Go to Next/Previous Event - The Rewind and Fast Forward buttons have been renamed and have new icons to reflect what the buttons actually do. The new names are Go to Next Event and Go to Previous Event.
• Composer Settings: Move (Formally the FF/Rew tab) - The options in the Move tab control how the position indicator moves when you use the Go to Previous and Go to Next buttons in your Avid editing application monitors.
• Searching for Items in the Timeline - With this release, when you search for items in the Timeline, the Find window will display the Timeline elements matching the search text.
• Mappable Segment Preview Button - You can now map the Segment Preview button. The button has been added to the CC tab of the Command Palette.
• Mapping Bin Fast Menu Commands to the Keyboard - You can map bin fast menu commands to the keyboard.
• Appending All Markers to EDLs, Cut Lists, and Change Lists - You can now append all Markers from a composition to an EDL, Cut List, or Change List. Previously, if the marker was in the composition but was not part of an event, it was not included in the output.
• Previewing In-Progress Sequences and Clips While Exporting - This feature allows you to link to a file that is still being exported (on another system).
• Video Data Rate Column Heading - You can now choose to display an additional bin column heading. The Video Data rate column displays the data rate of a linked clip.
• Support for Playback of 4 Streams of XAVC-I - This release of the editing application supports playback of 4 streams of XAVC-I in an UHD 59.94p project.

Fixed in v8.9.4: 

• Bug Number: MCET-2145. You could not export subclips as OP1a if the Use Marks option was selected.
• Bug Number: MCET-2075. While in the Effect Editing workspace, the editing application crashed when undoing changes in a Paint or AniMatte effect.
• Bug Number: MCET-2090. Even with “Copy all media” selected as the Export method for an AAF export, the entire clip was not copied.
• Bug Number: MCET-2168. Only the topmost clip of a group clip retained its LUT. All clips in a group clip now retain their LUT.
• Bug Number: MCET-2187. In some instances, you could not enable 12-channel or 16-channel in the Audio Project Settings even when “Allow 16 channel output” was selected.
• Bug Number: MCCET-2115. You might have received an “Insufficient Disk Space” error when importing multiple AVCHD clips.
• Bug Number: MCCET-2099. If you pressed the Enter key on the numeric keypad after renaming a track, the Rename dialog box would not close. Now, once you type a new name, the OK button is highlighted and pressing Enter on the numeric keypad will retain the new name and close the Rename dialog. This fix has also been incorporated into the Rename, Timeline Clip Notes, and Marker windows. The following applies when you are working with the Rename, Timeline Clip Notes and Marker dialogs:

•  
  • Pressing the Enter key on the numeric keypad will perform the task of whichever button has current focus, such as OK, Cancel, Remove, etc.
  • Pressing the keyboard Enter (Windows) or Return (Mac) key will add a line break if the cursor is active in the text area. If the cursor is not in the text area, the behavior is the same as pressing the Enter key on the numeric keypad.
  • Pressing Esc will cancel the dialog.
  • When you are in the dialog window, pressing the tab key will move the focus from one element to the next within the dialog.

• Bug Number: MCCET-2119. In some instances, if you performed a mix-down of a clip containing an audio suite effect, the editing application would hang during the render operation.
• Bug Number: MCCET-2165. You might have received an “Assertion failed” error when selecting an EVS Transfer Manager profile.
• Bug Number: MCCET-2088. (Interplay) The editing application might have hung when Media Stream Manager (MSM) was performing a rescan. This occurred if the media file folder name was in lower case. This has been fixed.
• Bug Number: MCCET-1979. (Windows) You might have seen ghosting or redraw issues when performing a trim.
• Bug Number: MCCET-2175. In a previous release of the editing application, the Master Audio monitoring fader default was -20. The correct default is 0.
• Bug Number: MCCET-2127. A grouped transcoded clip with a LUT applied would ungroup if you pressed the up or down arrow key while the clip was in the Source/Record monitor.
• Bug Number: MCCET-2128. Bullets (•) in a clip name did not translate properly in the List Tool.
• Bug Number: MCCET-2073. In some instances, pre-rendered source-side motion effects did not remain rendered when loaded into the Source monitor.
• Bug Number: MCCET-2117. The number of clips being transcoded in the transcoding process window did not always reflect the number of the actual clips being transcoded.
• Bug Number: MCCET-2108. Banding artifacts might have appeared when you transcoded XAVC Intra 100 to DNxHD (8-bit) media containing color transformations.
• Bug Number: MCCET-1902. After performing a batch reimport. .wav files might have had the wrong timecode.

• Bug Number: MCCET-2143. The first “Text to Find” field wasn’t automatically highlighted when you performed a Custom Sift.
• Bug Number: MCCET-2132. In some instances, the editing application did not return results when performing a search for text when “Scripts in Project” was selected as a search criteria. This has been fixed. NOTE: For this fix to work on existing scripts, you must open the script and then save it.
• Bug Number: MCCET-1981. After a batch re-import, a consolidated subclip and new master clip playback from the original master clip rather than the Mark-IN point of the subclip.
• Bug Number: MCCET-2109. Project info in the Project Selection window would sometimes show the wrong raster dimension.
• Bug Number: MCCET-2092. If the Transcode option was selected in the Export dialog, you might have received an “Exception” error when exporting a seq. with various frame rates as an AAF.
• Bug Number: MCCET-2024. In some instances, group clips would display n/a as the source name in the Timeline.
