Cedar 4.4 ReleaseThe purpose of this release is to fix several known bugs in boot file components.  No public interfaces have changed since Cedar 4.2 (or 4.1 or 4.0), but a few private interfaces have changed.  Users should read and follow the installation procedure (described below) carefully.This release is labelled Cedar 4.4 since the ISL folks have pre-empted Cedar 4.3.Bug fixes to packages that are not in the boot file may be found on the <PostCedar> directory.  This release does not incorporate those fixes.**** Known Problems ****Given the existence of improved packages on <PostCedar>, users should be warned that installation of Cedar 4.4 may acquire elderly versions of components from Cedar.  The file Init.log records what was acquired during installation.  Walnut, in particular, has a much better version on <PostCedar> than <Cedar>.  If the release installation acquires some elderly files from Cedar, you should simply get the more recent files from PostCedar after installation.  If it were easy to avoid this problem, we would.  The following commands can be used to restore PostCedar files that the Cedar release will overwrite:bringover /a /o Chat.bcd Chat.TIP [Indigo]<PostCedar>Top>Chat.dfbringover /a /p [Indigo]<PostCedar>Top>Forms.dfbringover /a /o RopeFileImpl.bcd [Indigo]<PostCedar>Top>RopeFile.dfbringover /a /o TSetter.bcd TSetter.icons [Indigo]<PostCedar>Top>TSetter.dfbringover /a /p [Indigo]<PostCedar>Top>Walnut.df**** Installation Procedure ****A machine already running Cedar 4.2 should upgrade to Cedar 4.4 with little problem.  Although we recommend erasing your Client and Debugger volumes before installing, there is no unusual risk associated with using your current volumes if you follow the instructions below.A machine running the prerelease of Cedar 4.4 needs the additional step of having the file named Cedar.version deleted from the disk before installing Cedar 4.2.  Avoiding this step will cause trouble for you when PreCedar is erased.For any user, to erase all files on your Client and Debugger volumes, boot the Othello volume, and typeerase Clienterase Debuggerconfirming as necessary.  Then you can execute the appropriate installation command file for your machine (see below).To install Cedar on a Dorado (whether or not you choose to erase volumes), boot the Othello volume, and type@[Indigo]<Cedar>Top>DoradoRelease.cmTo install Cedar on a Dolphin (whether or not you choose to erase volumes), boot the Othello volume, and type@[Indigo]<Cedar>Top>D0Release.cmTo install Cedar on a Dandelion, consult an expert.  To install Cedar on a public machine (an unusual case for most people), use PublicDoradoRelease.cm or PublicD0Release.cm.As with previous releases, once the automatic installation procedure completes, you may then optionally acquire many potentially useful files by typingBringOver /a CedarClientFat.df    (Note:  NOT /p)to the UserExec or CommandTool.  This will fetch the exported contents of most of the major packages, whether released as part of the boot file or as separate BCDs.  Users with limited disk space should not do this.  Even users with lots of disk space may find the clutter irksome.Again - Given the existence of improved packages on <PostCedar>, users should be careful that installation of Cedar 4.4 does not acquire elderly versions of components from Cedar.  The file Init.log records what was acquired during installation.  Walnut, in particular, has a much better version on <PostCedar> than <Cedar>.  Use the commands in Known Problems to restore more recent packages from PostCedar.Once you have brought over all the desired files, you may wish to make a checkpoint, using the guarded button Checkpoint at the top of the screen.Before beginning to use this release, you should read the remaining sections of this message.**** Significant Changes in this Release ****This section documents important changes in the user interface or major components and briefly describes significant new components.  The descriptions here are incomplete and intended only to provide sufficient information to avoid surprises and confusion.

Several bugs in AMTypes and BugBane related to remote debugging have been fixed.  Some of these bugs were also present for local debugging.2.  Some Viewers repainting bugs have been fixed.3.  A TIP parser bug has been fixed.4.  A disabling scrolling bug in ColorPackage has been fixed.**** System components ****The following is a complete list of the system components included in this release.  Details about the relationship of each component to the previous release and pointers to documentation and DF files appear in the "Summary of Release Components" section, below.The field after the package name indicates what has changed.  It can take the following values:new	component is new for this releaseold	component is unchanged for this release (DF file is from cedar 4.1)minor	component only has minor bugs fixed and/or simple recompilationmajor	component has significant changespost	component has more recent version on PostCedar** Packages of general interest **AMModel		old	In boot fileAMProcess		old	In boot fileAMTypes		minor	In boot fileBinder		oldBootTool		oldBravoToTioga    	oldBugBane		minor	Partly in boot file (InterpreterPackage)CedarReals		old	In boot fileCedarRoot		old	In boot fileCedarScanner    	minor	In boot fileCedarSnapshot	old	In boot fileChat		postCIFS		old	In boot fileClientFileTool	oldClock		oldCoFork		oldCommander		old	In boot fileCompiler		oldCypress		postDateAndTime    	old	In boot fileDebugTool		oldDFFiles		oldFileTool		oldFileTransferCommands	oldFlushUnneededTempFiles	oldFootBall		oldForms		postGrapevineUser	old	In boot fileGraphics		old	In boot fileIconRegistry		postIncludeChecker	oldInit		old	installation command filesIntervalTimer    	old	In boot fileInterpreterTool	minor	In boot fileIO		minor	In boot fileListsAndAtoms	old	In boot fileLupine		oldMaintain		oldManual		oldMCross		oldModeller		oldNewStuff		oldOnlineMergeSort	oldPerfStats		oldPlotPackage		oldPoplar		oldPrint		oldPup		old	In boot fileRandom		oldReadEvalPrint	old	In boot fileRedBlackTree    	oldRedBlackTreeRef	oldReminder		oldResource		old	In boot fileRigging		old	In boot fileSafeStorage		old	In boot fileSampleTool		oldScaled		oldSet		oldSirPress		oldSpell		old	In boot fileSpy		oldSTP		oldTalker		oldTank		oldTioga		old	In boot fileTIP		minor	In boot fileTSetter		postUECP		oldUnique		oldUserExec		oldUserProfile		old	In boot fileViewers		minor	In boot fileViewRec		oldVTables		oldWalnut		postWatch		oldWaterlily		old** Packages of special interest **AlpineUser		postAMEvents		old	In boot fileBasicHeads		old	In boot fileBCD		oldBooting		old	In boot fileBTree		post	Replaces BTrees.dfBTrees		old	Obsolete.

If the documentation file name is not a path, it is assumed to be accessible using the DF file name and BringOver, i.e.,BringOver /o DocFileName DFFileNameIn general, documentation is stored on[Indigo]<Cedar>Documentation>ComponentName.tiogabut there are occasional exceptions.  For brevity, we do not list Component.Press if Component.Tioga exists, and we do not include [Indigo]<Cedar>Documentation> in the file name if that is the prefix.  If not specified, the host is assumed to be [Indigo].Components are listed below only if there has been a change for this release.
