 Hi all,
DHIS version 2.19 is out. We have some great new features for you.

DATA ANALYSIS FEATURES----

Data ranges in event analysis: In event reports and visualizer you can define and display numeric values in ranges. This is useful e.g. for age, weight and scores where aggregate values can be presented in ranges such as “1-5”, “5-10” as opposed to by discrete numbers. The ranges are based on legend sets (must be created in GIS for now). You can enable ranges from a drop-down next to each data item in the left panel.

Plain tables in event reports: In event reports you can display the items from multiple data elements and attributes as a single dimension. Normally each data element is displayed a separate dimension. You can enable this from “Layout” > “Collapse data dimensions”. This allows you e.g. to create large reports with items from many data elements coming down on the rows.

Value dimension and aggregation operator in event analysis: In event reports and visualizer you can define which data element to use as the metric to display in the report or chart. You can also define which aggregation operator to use for that metric. E.g. you can now display the average weight or age in the report. You can enable this from “Layout” in the “Value” box.

Enrollment output type in event analysis: In event reports and visualizer you can select the output type, which refers to how the system counts the number of matches for the criteria. You can select between number of “events”, number of “enrollments” and number of “tracked entity instances” (persons). This is useful for tracker programs.

Hide n/a options in event analysis: In event reports and visualizer there is a new option for hiding n/a data items. Often, several data elements might not have a value for events which will lead to rows and columns with a count of n/a. From “Options” > “Hide n/a data” you can now easily hide all those items when desired.
Demo | Screenshot

This relative periods: New relative periods have been added for this week, this month, this quarter and this six-month in all five analysis apps and analytics Web API.

Aggregation type: In data visualizer you can specify the aggregation type for the chart items. You can select between sum, count, std dev, variance, max, and min. This is useful when more than one aggregation type is needed per data element. Std dev and max/min are useful to look for outlier values and data quality issues. The demo shows std deviation for immunization doses administered.

Identifier schemes in analytics output: You can choose between using UID, code and name as identifiers when you download pivot tables or access the analytics Web API. This is useful e.g. when you want to export aggregated data and exchange it with a third-party system which are synchronized on meta-data codes.

CONFIGURATION AND SYSTEM MAINTENANCE FEATURES----

Variable substitution in SQL views: You can insert variables directly in SQL views and pass in values to be substituted in the request URL. This adds flexibility in how you create SQL statements, and can improve performance since you can place variables in the main where query, as opposed to filtering the entire result set as it is done with the existing criteria function.
Demo | Docs | Screenshot

Materialized SQL views: You can create materialized SQL views. In the “add new SQL view” screen you can select “Materialized SQL view”. Materialized views store a copy of the actual result set of the view query. This performs better than regular SQL views which needs to be retrieved from the underlying table each time. The down

Option set and long text attribute types: Dynamic meta-data attributes can now be of type option set, which display as a drop-down selection field; and long text, which has no length limit and displays as a text area.
Demo | Screenshot

Resend user invitations: In the user app > list of users, you can re-send invitations to create user accounts by clicking on an unrealized account invitation. This is useful as people sometimes fail to notice the invitation email or it ends up in spam filters. Requires full system authority.
Screenshot

Identifier and code matching in GML import: The GML importer lets you match incoming features using UIDs and codes. Previously only matching name was supported. This is useful for scenarios where established identifier / code lists are in use.
Docs

Footers in email messages: A footer with a reply link has been added to email messages. This is useful in order to easily reply to messages which are read in an email client. This requires that you set “Server base URL” under general settings and configure an SMTP server under email settings.
Demo

Offline org unit level cache per org unit level: The number of organisation unit levels to cache offline for data entry purposes can now be controlled per organisation unit level. This is useful for global system implementations, e.g. where you have global users which do not need to do offline data entry and do not want to wait for a very large number of org units to be cached.
Screenshot

Analysis about page: All analysis apps now have an about page which shows time since last analytics table update, current DHIS 2 version, revision and username. This also applies to the about page under profile. This is useful when debugging and supporting end-users. Click on About in the top right corner on the demo.
Demo

Separate logs for background processes: Output from processes such as analytics table generation, data exchange and data synchronization are now written to separate logs. Main log is also written to a dedicated log file. These logs are found under DHIS2_HOME/logs and are capped at 50MB. Main logs are still written to standard out.
Docs


TRACKER AND EVENT FEATURES----

Location in map: In event capture you can set the location in terms of longitude and latitude for where an event took place directly from Google Maps. This requires that coordinate capture is enabled for the program. In the add new event form, click the blue icon next to longitude to open the map, then click on the map to set the location. Try it out on the demo on the “Information campaign” program.
Demo | Screenshot

Search in org unit tree: In tracker capture search you can now search across all organisation units that you have access to by opening an org unit tree inside the advanced search area. This is useful as you can now search across organisation units independently of which organisation unit you have selected for registration of persons in the left-side tree selector.
Demo | Screenshot

Enrollment status filter in search: In tracker capture search you can now filter on persons based on their enrollment status. The options are active, completed and cancelled enrollments. Use the 4 icons at the top to filter.
Demo | Screenshot

Custom form for person registration: You can define custom forms to use for registration of people and things. This is useful when you have detailed requirements of need for scripting for registration. You can create custom registration forms from Programs / attributes > Tracked entity form. Check it out on the demo by registering a child for the “Child Programme”.
Demo | Screenshot

Nicer program summary: The tracker program summary report is now easier to read and looks better. Each program stage appear in tabs, and each person or thing is displayed with event date and organisation unit.
Demo | Screenshot

Next and previous in dashboard: In tracker capture dashboard you can quickly navigate between persons and things by clicking on the next and previous button in the top left corner.
Demo | Screenshot

Tracker dashboard layout: The tracker dashboard now remembers the position of each widget between each time you access it.
Demo

Periodic events: You can capture events at fixed, periodic intervals. The period type of the interval can be set in the program stage management. When creating a new event for that stage the user is asked to enter a period, e.g. a month, instead of the usual date.
Screenshot


WEB API FEATURES----

Translations: Translations are now included in the standard meta-data payload, meaning you can easily export and import meta-data translations. Also, a locale query parameter can now be supplied to all meta-data resources to get the meta-data translated according to the desired locale.
Docs

Enum options: All valid options for enum-type properties are exposed through the API payload. This makes it easier to use such properties in apps. See e.g. report table > aggregation type property.
Demo

Meta-data validation: Meta-data is now being validated according to constraints such as min and max-length and not null. You can investigate current constraints and validate your payload against the schemas resource to check validness.
Docs

Merge strategies: When importing meta-data now you can now define whether the API should merge existing properties or overwrite when updating objects.
Docs

Approval level parameter in analytics: You can define an explicit approval level in analytics request which tells the system to only include data up to that approval level in the aggregation.
Docs

Data validation: Data values for a data set can be validated according to relevant validation rules using the new validation resource.
Docs

Identifier schemes for event export: You can now choose between using UIDs or codes as identifiers for event export payloads.
Docs

Preheat cache for data import: The dataValueSet data import resource now supports a preheat cache option for controlling whether to load all necessary meta-data into memory before import.
Docs

Scheduling: All background tasks such as analytics table generation and data monitoring can be scheduled through the new scheduling resource.
Docs

Field filtering: Support for filtering of fields has been added to the schemas, properties and dimensions resources.
