Release Notes for 1.6.0:
52
------------------------
53

  
54
This release comes with more performance improvements, initial support for 
55
LSIDs (Life Sciences Identifiers) and FGDC standard, more controls for 
56
Metacat administrators and bug fixes. Below is the list of bug fixes and
57
performance improvements.
58

  
59
Bug Fixes: 
60
* Improved the indexing algorithm. Earlier indexing failed for some documents 
61
  randomly and used to take a lot of time to complete for others. The 
62
  code for indexing was changed to take care of both these problems.
63
* Earlier, xmlns prefix was used to determine the namespace of the document. 
64
  Now schemaLocation is used instead xmlns prefix to determine the namespace 
65
  of the document as that is a better indicator of document type. 
66
* INSTR was used in some SQL statements and it is not supported by Postgres. 
67
  So SQL statements were modified so that INSTR is not used.
68
* Replication was changed to include replication of deleted documents also. 
69

  
70
New Features:
71
* Added FGDC schema and XSLT so that Metacat can handle FGDC standard
72
* Added support for LSID. This includes modifying the stylesheets to 
73
  display the LSIDs, modifying the build to include a new target 
74
  'install-ldap'.
75
* Added following access control levels to Metacat:
76
    1. Administrators - users who can do the following:
77
       a. Run replication
78
       b. Delete any document
79
       c. Modify any document
80
       d. run indexing for any document
81
       e. check the logs
82
    2. allowedUsers - User who are allowed to submit
83
    3. deniedUsers - Users not allowed to submit
84
* Added a new skin for Ecological Society of America. 
85

  
86
Performance:
87
* Reduced size of xml_nodes by creating a new table for holding nodes from 
88
  deleted documents and old revisions of the documents. 
89
* Provided a new variable in metacat.properties where more frequently searched 
90
  for paths can be specified. Seperate indexes are created for these paths 
91
  - so that search is faster.
