Details
July 15, 2019, saw a new APK update to Pokemon GO.
The update brings several changes, including the removal of the Back button "trick" for catching on Android, but the most notable change is to the IV appraisal system.
Appraisal Screen Updates
Redditor u/Pokescout first posted a screenshot of the new system, which shows highly detailed IV information in the form of a bar graph.
Swiping left and right on the appraisal screen will automatically apply the appraisal to the next Pokemon, making the system much quicker for appraising multiple Pokemon.
100% IV Pokemon have a red stamp
Reddit user /u/BruteBooger noticed that Pokemon with 100% IV's have a red stamp.
UI improvements
Charged Attack Mechanic Changes
The video released by Niantic indicates that charge moves in PVP will require players to swipe and match the pattern of the icons falling across your screen. This might infer that the more accurate your are, the more powerful your attack will be.

Where is Team Rocket?
Redditor u/Fillain discovered that Shadow and Purified now exist as search filters. If you watch the uploaded video, you'll notice that when the name "purified" is entered, Pinsir disappears, indicating that "purified" is a dedicated search term. This ultimately points to a Team Rocket related event coming soon.
A screenshot from Charles Twitch Stream also indicates that Shadow Pokemon are coming soon.
