Hi all,

DHIS version 2.22 is out with a lot of great new features and improvements.

Log in with admin/district on the demo <http://play.dhis2.org/demo/> system.


Data elements and indicators app: A completely new app for data elements
and indicators maintenance features a much slicker user experience, with
on-the-fly search, “access” and “last updated” visible in the lists, a new
group editor, and much better looks.

Integrated tracker analytics: Tracker-type data elements, attributes and
program indicators can now be included in aggregate indicators. This allows
for creating integrated analysis through indicators where e.g. the
numerator is being collected in a program while the numerator is collected
in an aggregate form. This means that you can produce integrated analysis
without caring about whether the data comes from routine forms, anonymous
events or tracking.

Multiple programs in favorites: Data elements and attributes from any
number of programs can now be included in the same pivot table or chart
favorite.

File cloud storage in tracker: The tracker capture and event capture apps
now support file storage for data elements of type file. This allows you to
use tracker as a document repository, and to upload documentation and files
related to events or people. Files can be stored either on the Web server
or sent directly to AWS S3 <https://aws.amazon.com/s3/> cloud storage.

Tracker data audit: Tracker capture and event capture now store the audit
trail of changes to data and make it readily available by clicking on the
audit icon next to each input field in the form. This is useful to view
historical changes to information and a requirement in many settings where
sensitive data is being stored.

Screenshot <https://www.dhis2.org/images/222/tracker-capture-audit.png>


Improved tracker capture: The tracker capture app has received a range of
improvements.

- Yes/No fields are rendered as radio-buttons instead of drop-downs for
faster data entry.

Screenshot <https://www.dhis2.org/images/222/tc-radio-buttons.png> | Demo
<https://play.dhis2.org/demo/dhis-web-tracker-capture/index.html#/>


- The enrollment and active programs widget have been merged for better
usability.

Screenshot <https://www.dhis2.org/images/222/tc-enrollment-widget.png>

- Easy search for option sets: Option sets can be searched from within the
data entry widget.

Screenshot <https://www.dhis2.org/images/222/tc-option-set-search.png>

- Enrollments can be incompleted in order to change existing values.

Screenshot <https://www.dhis2.org/images/222/tc-incomplete-enrollment.png>

- You can filter for people who have a scheduled event today.

- Tracker data element and attribute values can contain up to 50’000
characters.

- The widgets in the tracker dashboard displays a loading indicator until
data is available.

- Whether to include due date input field can be configured per program.

- Whether to list people on the front page can be configured per program.


Encryption: Tracker now lets you encrypt identifiable / confidential
information in the database. You can set a tracked attribute to
“confidential”, which will encrypt the information you capture for it. This
protects against attacks directly against the database. Note that due to
the nature of encryption you cannot query or do analytics for encrypted
attributes. Encryption requires some extra configuration which is outlined
in the docs.

| Screenshot <https://www.dhis2.org/images/222/attribute-encryption.png>


LDAP: DHIS 2 now supports authentication against an LDAP server. This is
useful in order to centralize user credentials across multiple systems. The
LDAP connection can be specified in the dhis configuration file. A DHIS 2
user account can be matched to a directory entry through the username or
through an explicit “LDAP identifier” set for each user.

Docs
<http://dhis2.github.io/dhis2-docs/master/en/implementer/html/ch08s05.html>

Integrated app store installation: The apps management app has been
rewritten and now lets you install apps from inside your own DHIS 2
instance directly from the app store at dhis2.org/appstore
<https://www.dhis2.org/appstore>. This means that there is no practical
distinction between the core apps (apps being part of the DHIS 2
installation) and external apps (residing in the app store).

Demo <https://play.dhis2.org/demo/dhis-web-app-management/#> | Screenshot
<https://www.dhis2.org/images/222/integrated-app-store.png>


Approval workflows: You can now create data approval workflows where each
defines a list of data approval levels. Several data sets may be associated
with a data approval workflow. This implies that you can have multiple
parallel approval workflows in the same system. As an example, health
facility reporting may have to be approved at district and provincial
level, whereas district population data might have to be approved at the
national level only. Approval levels and workflows can be configured in the
settings app.

Aggregate functions in surveillance rules: For validation rules of type
surveillance you can now specify aggregate functions such as average,
count, std dev and median. This is useful e.g. in order to identify disease
outbreaks and ignore outliers or poor-quality data.

Docs <http://dhis2.github.io/dhis2-docs/master/en/user/html/ch12s05.html>


Organisation unit translations: You can now translate the names and short
names of organisation units and have those names be reflected in the
hierarchy.

Screenshot <https://www.dhis2.org/images/222/org-unit-translations.png>


Unique meta-data attributes: Meta-data attributes can now be unique,
meaning the system will enforce uniqueness for the attribute values for
each object type. This is useful as you can use attributes for various
identifiers, e.g. personal identifiers and batch identifiers. Dynamic
attributes are now also supported for option sets, options and resources.

Docs <http://dhis2.github.io/dhis2-docs/master/en/user/html/ch22s14.html> |
Screenshot <https://www.dhis2.org/images/222/unique-metadata-attributes.png>


Data value bulk delete: A new import strategy for deleting data values is
supported in order to make it easier to delete bulks of data.

Analytical object deletion handling: Associations to pivots, charts and
maps will be removed when deleting data elements, indicators, data sets and
organisation units.

Screenshot
<https://www.dhis2.org/images/222/analytical-object-deletion-handling.png>


User replication authority: The ability to replicate users can be granted
through a new authority “Replicate user”.

Screenshot <https://www.dhis2.org/images/222/user-replication.png>




WEB API FEATURES

------


ADX data export: You can now export data in the ADX format natively using
the dataValueSets Web API resource with content type application/xml+adx.

Docs
<http://dhis2.github.io/dhis2-docs/master/en/developer/html/ch01s14.html#d5e1781>


Dynamic identifier schemes: For data imports you can now specify unique
meta-data attributes as identifier schemes. This implies that DHIS 2 can be
used to store any number of sets of identifiers and map data to those
during import. This is useful when DHIS 2 is used to integrate data from a
large number of systems and each have their own sets of identifiers.

Docs
<http://dhis2.github.io/dhis2-docs/master/en/developer/html/ch01s13.html#d5e1390>


SMS: SMS can now be completely managed through the Web API, with new
resources for sending and receiving SMS, starting and stopping the SMS
service and configuration of SMS gateways. The system has now built-in
support for five popular SMS gateway providers. The SMS services have been
revamped and made more scalable.

Docs
<http://dhis2.github.io/dhis2-docs/master/en/developer/html/ch01s38.html>


App store: The contents of the DHIS 2 app store is available at the appStore
resource, which also allows you to install apps from the app store with a
POST request.

Docs
<http://dhis2.github.io/dhis2-docs/master/en/developer/html/ch01s61.html>


Field filter operators: A range of new field filter operators has been
added, such as ^(like/ilike) to match from start of string and $(like/ilike)
to match from end.

Docs
<http://dhis2.github.io/dhis2-docs/master/en/developer/html/ch01s08.html>


Tracker bulk deletion: Bulk deletion of events, enrollments and tracked
entity instances are now supported through a new delete import strategy.


Docs
<http://dhis2.github.io/dhis2-docs/master/en/developer/html/ch01s53.html>


Async data value import: Data values can now be imported asynchronously
through a new async parameter, meaning you can post a large import file and
poll for the results rather than having the response block until the
process is done.

Docs
<http://dhis2.github.io/dhis2-docs/master/en/developer/html/ch01s13.html#d5e1390>


Data pruning by org unit: Data, complete data set registrations and
approvals can be removed by organisation unit through the
maintenance/dataPruning resource.

Docs
<http://dhis2.github.io/dhis2-docs/master/en/developer/html/ch01s34.html>


Typed user settings: You can now set all user settings through the
userSettings resource, including those of complex types.

Docs
<http://dhis2.github.io/dhis2-docs/master/en/developer/html/ch01s42.html>


Data value deletion: Data values can now more easily be deleted through a
new delete import strategy, which lets you indicate explicitly that the
posted data values should be deleted.

Docs
<http://dhis2.github.io/dhis2-docs/master/en/developer/html/ch01s13.html#d5e1390>



SERVER MANAGEMENT FEATURES

------


System read-only mode: You can now set the system to start in read-only
mode which means that no database write-operations will be executed when
the system starts and when people are loggging in. This is useful in order
to run DHIS 2 on read-only database replicas for horizontal scaling
purposes.

Docs
<http://dhis2.github.io/dhis2-docs/master/en/implementer/html/ch08s07.html>


General configuration file: The DHIS 2 configuration file has been renamed
to dhis.conf, and the configuration properties have been given general
names, removing the association to the Hibernate framework.

Docs
<http://dhis2.github.io/dhis2-docs/master/en/implementer/html/ch08s03.html#d5e500>
