Hi all,

DHIS version 2.20 is out and has a lot of great features and improvements.

You can log in with admin/district on the demo system.

Program indicators and data elements in aggregate analytics apps: You can
now get aggregate data for program indicators, tracked entity attributes
and tracker data elements in the pivot table and data visualizer apps. This
means that you can produce aggregated results straight from events and
programs without going through aggregation queries. It also means you can
create pivots and charts which combines aggregate indicators and data
elements with event/program-based indicators and data elements.

Flexible internal ordering of data items: In pivot table and data
visualizer apps you can now arrange various data items such as indicators,
data elements and data sets in any internal order. All data items have been
merged into a common “Data” selection which provides a drop-down for
selecting the various types of data items.

Program indicator filter: Program indicators now has a filter property. In
analytics, this property will filter the events data source before the
expression is being calculated. Now that program indicators are supported
in analytics, this is useful e.g. to produce analysis based on stratified
sampling, where the calculations can be based on age groups, wealth
quantiles and so on. You can create program indicators from the context
menu of a program.

Program indicators in data entry: Tracker capture and event capture apps
can now display calculated values for program indicators on the fly in data
capture forms.

Section selector in event capture: Event capture now supports a section
selector which makes it easier to navigate between sections in long forms.

Default tracker dashboard layout: In tracker capture, users with the right
privileges can now define default layout of tracker dashboards per program.
Inside the dashboard, from the widget selector you can choose “save
dashboard layout as default”.

Screenshot <https://www.dhis2.org/images/220/tc-default-dasboard.png>


ADX data exchange format: This release includes early support for a new
standard for aggregate data exchange called ADX.  ADX is developed by the
Quality Research and Public Health (QRPH
<http://wiki.ihe.net/index.php?title=Quality,_Research_and_Public_Health>)
technical committee of the IHE consortium and is based largely on dxf2. The
final version of the standard is due to be published later this year.

Docs <https://www.dhis2.org/doc/snapshot/en/developer/html/ch01s12.html>


Approval level option in pivot table: The pivot table app now has an
approval level option for explicitly defining the approval level for which
data in the pivot table must be approved up to. This is useful for when
doing user support and for viewing data approval status. This is only
visible when the “hide unapproved data” setting is enabled.

Screenshot <https://www.dhis2.org/images/220/pt-approval-level.png>


Dynamic dimension filters: The pivot table and data visualizer apps now
provide item filters also for dynamic dimensions.

Demo <https://apps.dhis2.org/demo/dhis-web-pivot/index.html> | Screenshot

All items selector: In pivot table and data visualizer apps, you can now
select “all items” next to dynamic dimensions in order to render all
dimension items in the pivot table / chart. This is used to optimize the
request going to the server and fixes the problem of “request URL too long”
which is often encountered when creating very large pivot tables.

Refresh materialized view: You can now refresh a materialized SQL view from
the context menu of the SQL view.

Screenshot <https://www.dhis2.org/images/220/refresh-materialized-view.png>


Open future periods for data entry: A new property for controlling
explicitly how many future periods should be available for data entry has
been added to data sets. This is an improvement of the current solution
where you can only control whether data should be entered for future
periods or not. The data set property is called "open future periods for
data entry".

Demo

Program rules: The tracker and event capture app now have support for
program rules. Program rules are defined per program. A rules is a
mechanism for allowing dynamic behavior referred to as program rule
actions. The first fully supported type of dynamic behavior is skip logic
which makes it possible to hide data elements and sections based on program
rules expression.

Some conceptual examples are 1) hide the field for entering HIV test
results if another field has indicated that no HIV test is performed and 2)
hide field for entering number of pregnancies if the tracked entity
attribute “Gender” indicates that the person is a man. There is an ongoing
effort to support other actions/dynamic behaviors. We will get back shortly
with tutorials.

Skip logic in event capture: The event capture app now supports skip logic,
i.e. hiding data element input fields and sections based on certain
conditions and values of other data elements. This is based on the new
program rules model.

Help text in tracker capture: The tracker capture data entry shows an
information icon next to the data elements that contain a description.
Clicking the icon reveals the data element description.

Constant and program indicator sharing: Constants and program indicators
now support sharing. Constants also has received code, short name and
description properties.

Screenshot <https://www.dhis2.org/images/220/program-indicator-sharing.png>


Program data entry form navigation: To create a custom program registration
form you can use the program context menu and click “Create custom
registration form”. This makes navigation easier compared to the current
separate left menu item.

WEB API FEATURES

----

OAuth2 authentication support: OAuth2 <http://oauth.net/2/> is an
industry-standard protocol for authentication between applications. This
allows for more secure, reliable and standards-based authentication between
systems.

Docs
<https://www.dhis2.org/doc/snapshot/en/developer/html/ch01s02.html#d5e75>

Web message error response: A new format for warning and error messages
have been introduced consistently across all Web API resources. It contains
properties for http status, http status code, message and application
status.

Docs <https://www.dhis2.org/doc/snapshot/en/developer/html/ch01s03.html>

Tracked entity instance object query: A new resource for querying tracked
entity instances which returns the full objects in the response has been
added. This is suitable for clients such as Android apps that need to
download and synchronize all information about tracked entity instances.

Docs <https://www.dhis2.org/doc/snapshot/en/developer/html/ch01s42.html>

GML error feedback: The GML importer has been made more robust and now
provides proper user feedback when something goes wrong.

Last updated and limit for data values: The data value sets resource now
supports parameters for getting data values updated after a given time and
for controlling the max limit of data values to return.

Docs
<https://www.dhis2.org/doc/snapshot/en/developer/html/ch01s11.html#d5e1433>

Program rule import-export: Program rules, program actions and program rule
variables are supported in meta-data import-export.

Enrollment query with last updated parameter: The enrollment query resource
has been greatly improved and now lets you filter by last updated.
