Android Police spotted the update first and has detailed the changes in the Google Play Store app after update with build number 4.5.10. The new update for Play Store introduces the in-app purchase indicator that inform users about a possible transaction in an app, beforehand.
Another change the update brings is to review layouts. The star ratings for the review have been enlarged with edit button for making required changes to the review. In addition, Google has now added an option to delete your review. Now the Play Store app comes with a new activity feed that is integrated with the user's Google+ profile. Users can now share and view the Play Store activity with others via Google+ profiles. The new activity feed also features +1s and ratings buttons.
Earlier, Google announced a major update to its Google Search app for Android which would now show app results, including Google Play app listings, or from those already installed on the user's smartphone. With the new update, Google introduced three types of app listings which would appear depending on the search - these are 'Open in app', 'Google Play buttons', and 'Download button'.
The 'Open in app' result would show if a search term is found in an app already installed on the user's smartphone. The 'Google Play buttons' result would show when a slightly ambiguous search query is found in more than one app. The group of apps would be listed, and users can click the Google Play button on any of the apps to go to the Play Store app, and install the app if they wish. The 'Download button' result would show when a user searches for an exact app on Google Search for Android. When users press the button, the relevant app will be opened on the Play Store app, and the download would begin automatically.
