23 <LI> Final check of the jpeg sub-library: all 'classical' jpeg
24 compressed Dicom files can be read<br>
25 <LI>All the previously gdcm-breaker images are now readable<br>
26 <LI> A huge number of memory leaks removed
27 <LI> Improvement of write process
35 <LI> A.P.I. breaking modifications (since previous version)
37 <LI> Use of <TT> namespace</TT> : all the methods formerly called
38 <TT>className::gdcmXxx()</TT> are now called <TT>className::Xxx()</TT>
39 <LI> Removal of accessors <TT>GetXxxByname</TT>, <TT>SetXxxByname</TT>
40 and <TT>GetXxxByNumber</TT>, <TT>SetXxxByNumber</TT>
41 replaced by <TT>GetXxx</TT>, <TT>SetXxx</TT>
42 <LI> a <TT>gdcm::Document</TT> is now specialized
43 in <TT>gdcm::DicomDir</TT> and <TT>gdcm::File</TT>
48 <LI> gdcm doesn't read yet JPEG-LS and JPEG2000 encoded files.
49 <LI> Allow user to tell <TT>gdcm::Document</TT> constructor he doesn't
50 want to deal with <TT>SeqEntry</TT (every time it's possible)
51 <LI> Allow user to tell <TT>gdcm::Document</TT> constructor he doesn't
52 want to deal with Shadow groups
53 <LI> Allow user to tell the Writer he doesn't want to write down
54 <TT>SeqEntry</TT> (if any)
55 <LI> Allow user to tell the Writer he doesn't want to write down
56 Shadow groups (if any)
57 <LI> <TT>Icon Image</TT> management (Read and Write)

66 Private Dicom Dictionary (pfff!...)
67 <LI> An accurate <TT>SerieHelper</TT>
72 <LI> <TT>DocEntrySet::InsertSeqEntry</TT> never used, never checked ...
73 <LI> The difference between <TT>MONOCHROME1</TT> and <TT>MONOCHROME2</TT>
74 is not taken into account. It's up to the user to change the pixels
76 <LI> Writing a 'True Dicom' image after reading an ACR-NEMA image requests
77 from the user to build up 'manually' the Meta Elements group (0002)
78 <LI> Management, on Big Endian Processors, of unloaded BinEntries
85 For people who get this new release :
87 We consider now that :
88 - any dicom related file is a gdcm::Document.
89 - a gdcm::Document can be :
90 - a gdcm::File, if it contains pixel data,
91 - a gdcm::DicomDir, if it contains only informations
92 on the files in a given directory
94 - in a gdcm::Document, there are gdcm::DocEntry, that can be :
95 - gdcm::ContentEntry (any entry that has an actual value,
96 *not* an embedded set of other gdcm::DocEntry)
97 a gdcm::ContentEntry can be :
98 - gdcm::ValEntry (whose value is std::string representable
99 e.g. character values, or integers),
100 - gdcm::BinEntry (whose value is not std::string representable
101 e.g. color palettes, overlays, icons , ...)
102 - gdcm::Sequence (no proper 'value', but a set of gdcm::SQItems,
103 composed of a set of gdc::DocEntry, recursively)
105 - in a gdcm::DicomDir, we only deal, hierarchically, with :

127 <TT>gdcmHeader</TT> class and <TT>gdcmDicomDir</TT> class.
128 <LI> Massive modifications in the Class Diagram :
130 <LI> Entries (<TT>gdcmEntry</TT>) are now separated into
131 <TT>ValEntry</TT> and <TT>SeqEntry</TT> (whose VR =
