48: Change History (most recent first):
49:
50: <CS11> 10/29/97 djb Add clump size factor. Increase kMinHFSPlusVolumeSize to 32 MB.
51: <CS10> 10/23/97 msd Bug 1685113. Add a createDate parameter to
52: InitializeHFSPlusVolume.
53: <CS9> 9/26/97 DSH Moved HFSPlusDefaults to DiskInit.i
54: <CS8> 9/5/97 msd Add a parameter to InitHFSVolume to indicate alignment of
55: allocation blocks.
56: <CS7> 9/4/97 msd In HFSPlusDefaults, specify the clump and node sizes of the
57: attributes file. Bump kHFSPlusDefaultsVersion to 1.
58: <CS6> 7/18/97 msd Include DiskInit.h.
59: <CS5> 7/2/97 msd Add prototype for GetMediaInfo driver status call.
60: <CS4> 6/17/97 msd Change minimum HFS Plus volume size to 2 MB (so we can test with
61: RAM disks). Added version and flags fields to HFSPlusDefaults.
62: <CS3> 6/11/97 msd Remove the #pragma load; this should be done by source files,
63: and generally not interface files. (Allows the test tools to
64: build separately from HFS Plus.)
65: <CS2> 6/6/97 djb Change kMinHFSVolumeSize to kMinHFSPlusVolumeSize and make it
66: 20MB
67: <CS1> 4/28/97 djb first checked in
68: <HFS5> 3/3/97 djb Add new fields to DriveInfo and HFSPlusDefaults.
69: <HFS4> 12/19/96 djb Changed kMinHFSVolumeSize so we can make HFS+ floppies for
70: debugging.
71: <HFS3> 12/10/96 msd Check PRAGMA_LOAD_SUPPORTED before loading precompiled headers.
72: <HFS2> 12/4/96 DSH Precompiled Headers
73: <HFS1> 12/4/96 djb first checked in
