 - 8th Apr 2008 libburn-0.4.4 has proven to be capable of burning to DVD+R/DL
   and read performance on disk file pseudo-drives has been improved.
 
+- 27th Apr 2008 libisofs-0.6.4 can now read data file content from images
+  and can map pieces of disk files onto image files. Image directory iteration
+  has been enhanced. Input data streams and extended information have been
+  exposed in the API to allow future development.
+
+- 29th Apr 2008 libisoburn-0.1.4 was made more efficient with reading of
+  image tree nodes. It now depends on libisofs-0.6.4 and libburn-0.4.4.
+  xorriso makes use of new libisofs features by performing incremental
+  updates of directory trees and by cutting oversized data files into
+  pieces. A primitive single session emulation of cdrcord and mkisofs is
+  provided.
+
+- 10th May 2008 libburn-0.4.6 supports formatting and writing of BD-RE,
+  full nominal speed for DVD-RAM and BD-RE. cdrskin has a unified blank
+  type with automatic media state recognition.
+
+- 17th May 2008 an old bug with DVD-RAM and now with BD-RE is fixed by
+  libburn-0.4.8 to allow libisoburn emulation of multisession on those media.
+
+- 19th May 2008 libisoburn-0.1.6 brings better table-of-content emulation
+  on overwriteble media and disk files.
+
+- 1st Jun 2008 libisofs-0.6.6 fixes some problems around device files.
+
+- 3rd Jun 2008 libisoburn-0.1.8 fixes a bug with overwriteable media.
+
+- 23rd Jun 2008 libisoburn-0.2.0 introduces extraction of files from
+  ISO images.

+-------------------------------------------------------------------------------
+DVD-RAM and BD-RE formatting :
+
+Although DVD-RAM usually are sold formatted, there may still arise the wish
+to adjust formatting.
+BD-RE are sold unformatted and need to be formatted prior to usage.
+
+Two format types are relevant for DVD-RAM : 00h and 01h.
+00h offers the default size format and usually a maximum payload size format.
+Even with that maximum size payload there is hardware defect management.
+(mmc5r03c.pdf 6.5.4.2.1.2)
+01h allows to convert payload capacity into spare blocks for defect
+managment. There is no way to increase payload capacity by format 01h.
+(mmc5r03c.pdf 6.5.4.2.2.1)
+
+With BD-RE there are three format types : 00h, 30h and 31h.
+00h offers the default size format.
+30h offers several sizes with defect management. Usually there are three
+size to choose: #1: default size, #2: maximum spare area, #3: minimal spare.
+31h offers a single size and disables defect management. This has the side
+effect to speed up writing to nominal speed.
+(mmc5r03c.pdf 6.5.4.2.15, 6.24.3.3, Table 472)
+
+Only format sizes from the list of format descriptors are permissible
+for DVD-RAM. The format list can be obtained by 23h READ FORMAT CAPACITIES.
+It also includes a description of the current formatting state.
+(mmc5r03c.pdf 6.24, 6.24.3.2, 6.24.3.3)
+
+Formatting is done by command 04h FORMAT UNIT. Its data payload consists
+of a Format List Header and a Format Descriptor. It is advisable to set
+the Immed bit and the FOV bit in header byte number 1. The descriptor should
+be a copy of a descriptor from 23h READ FORMAT CAPACITIES.
+(mmc5r03c.pdf 6.5, 6.5.3.2, 6.5.3.3)
+With nearly all formats Sub-type should be set to 0. But with BD-RE formats
+30h and 31h the Sub-type selects the certification mode.
+Usable with 30h seem 10b Full Certification and 11b Quick Certification.
+Usable with 31h seem also 00b Quick Reformat and 01b No Certification.
+(mmc5r03c.pdf 6.5.4.2.15.1)
+
+Other format types have their certification intensity controlled by
+a pair of bits: CmpList and DCRT.
+CmpList resides in CDB byte 1 as bit 3. DCRT resides in the payload byte 1
+as bit 5. Both together should request a quick size change without lengthy
+certification but maintaining the list of known defects.
+(mmc5r03c.pdf 6.5, table 249, 6.5.3.2)
+With DVD-RAM on my PHILIPS SPD3300L drive they prevent any format size
+change though. The TSSTcorp SH-S203B works properly.
+With BD-RE format 00h, the default is specified to be Quick Reformat,
+and with 00h in general certification can only be disabled not enabled.
+(mmc5r03c.pdf 6.5.4.2.1.7)
+
+
+-------------------------------------------------------------------------------
+DVD-RAM and BD-RE tuning :
+
+A special aspect of DVD-RAM and BD-RE is their low speed with write operations,
+which usually is only half than the nominal speed of media and drive.
+This is blamed to the automatic checkreading which happens ifor managing
+eventual defects. 
+
+Defect management of BD-RE can be disabled by format type 31h. See above.
+There is no drive known yet which would apply command 2Ah WRITE10 to DVD-RAM
+with full speed.
+
+The only known way to get full speed from DVD-RAM or BD-RE with enabled defect
+management is the use of AAh WRITE12 with Streaming Bit set to 1.
+(mmc5r03c.pdf 6.45)
+With some DVD-RAM drives this fails if a write buffer is not full 32 kB.
+With the tested BD-RE ione has to write write full 64 kB buffers.
+
+Although it seems not optimal, this is specified not only to disable the
+cumbersome checkread but also to ignore known defects and to write data
+to these defective addresses.
+(mmc5r03c.pdf 4.8.5)
+So the speed-up is only advisable as long as the media are free of
+incorrectable errors.
+
+Caveat:
+MMC-5 does not guarantee AAh WRITE12 to work on DVD-RAM or BD-RE at all.
+None of the features of profiles 0012h and 0043 promises the existence of
+AAh WRITE12.
+Nevertheless it worked on all tested drives is proper alignment was observed.
