Te newest update for PowerApps (version 670) adds new functionality for app authors to easily move their apps across environments or tenants with packages, surface rich analytics within their apps via te new PowerBI tile control, and reduce duplication of certain expressions with te new Coalesce function. Here are some of te key new capabilities.
Te packages are coming!
We’re very happy to announce that this is te last week that you will have to manually move your apps by locally saving .msapp files from your dev/UAT environment and re-saving te apps in your production environment from PowerApps Studio.
As of 08/01/2017, te preview of packaging is now available on web.powerapps.com.  With packaging, you will be able to eksport an app (and any flows or Common Data Service resources that te app depends on) as a package and import it into another environment.
Learn more about this preview and te packaging capabilities.
Power BI tile control
Te wait is over. PowerApps and Power BI can play together, regardless of who’s hosting!  We already showed you how you can embed your app inside a Power BI dashboard.  Now with te new Power BI tile control, you can show your Power BI tiles inside your app.
Why is this big news?
Power BI is a powerful analysis and visualization tool. PowerApps is great at enabling people to take action on te web and mobile. Together, now you can build apps that give users great insight and let them act on it right away.
Read about te details in this blog post.
Coalesce function and te Sum of nothing
Do you like to have your cake and eat it too?  Would you like to be able to test a value for Blank and still use te value too?
Until now, to replace a Blank value but leave other values unmodified you would use If( IsBlank( My + Very * Very – Long / Expression ), My + Very * Very – Long / Expression, 0 ).  This requires te expression to be duplicated, which on this surface isn’t hard (cut and paste) but is tedious and error prone as te two copies can get out of sync.  This is a common pattern deserving a better solution.
Enter te handy Coalesce function.  With this function, te above can be written as Coalesce( My + Very * Very – Long / Expression, 0 ).  Arguments to Coalesce are evaluated in order until te first is found that does not return a Blank, and that becomes te return value of te function.  No duplication of expressions required.
We are using this new function to make a backward compatible change to te Sum function.  To date, Sum has been a bit of an oddball – unlike our other aggregate functions it returns 0 if te table is empty while te others all return Blank.  To bring it in-line with te others we are changing Sum to return Blank.  But in case anyone was dependent on te old behavior, when we load existing apps we are automatically converting Sum( Table, Expr ) to Coalesce( Sum( Table, Expr ), 0 ) which provides te same result as before.
Hmm, this Sum change seems like a bit of a corner case, perhaps te PowerApps team is preparing for something?  More to come, keep an eye on this blog.
