### 5.4.1 View Release Notes
Release Notes are generated automatically when a new taxonomy version is released. It includes all the changes the new Taxonomy reflects: attributes, value lists and values that have been added, edited or deleted.
The Taxonomy version has four digits and consists of the following fields:
· Major
· Minor
· Revision
· Build
When a new Taxonomy is released, depending on the changes in its items, the version is auto-matically populated based on these rules:
· **Major**: It will be increased if any of these changes have been applied:
ü Entity related:
o Add Entity
o Delete Entity
o Add entity relation
o Delete entity relation
o Change Entity (only allowed changes)
· **Minor**: It will be increased if any of these changes have been applied:
ü Attribute related:
o Delete Attribute
· **Revision**: It will be increased if any of these changes have been applied:
ü Attribute related:
o Add Attribute
o Change attribute (only allowed changes)
ü Attribute values related:
o Change value limits
· **Build**: it will be increased if any of these changes have been applied:
ü Attribute values related:
o Add values
o Delete values
o Move values
o Change values (only allowed changes)
o Change value lists (only allowed changes)
The Name of the SRIS central taxonomy is ‘SRIS’ concatenated with the four-digit version code. e.g.: SRIS '6.3.0.1'. If a Custom Taxonomy exists for the Officer’s Authority, the Name will be SRIS\_DE\_ '6.3.0.1' (C#), where the # is the number of the custom taxonomy starting from cero (0).
When the Officer selects ‘View Release Notes', the system opens the Release Notes of the specific taxonomy:
