Oh my! **[Firebase](https://daily.dev/sources/firebase-blog)** · 8 min read · 0 upvotes · 0 comments ## Summary Firebase announced a wave of new products and feature improvements: a new In-App Messaging product for engaging active users with targeted contextual messages, a redesigned FCM reporting dashboard with send/impression/open stats, change history and rollback for Remote Config, new Crashlytics integrations with BigQuery and Jira, Cloud Firestore scaling to 10,000 writes/sec and 1 million concurrent users, Cloud Functions reaching general availability with an SLA, multi-site hosting support, faster CLI deploys from v4.1.0, and an overhauled Project Overview console page. The company also invited developers to the Firebase Summit in Prague on October 29th. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is Firebase In-App Messaging and how does it work? Firebase In-App Messaging is a product launched to send targeted, contextual messages to users actively using an app, rather than notifications that pull users back in. Messages can be customized by format, color, and call-to-action, and integrate with Google Analytics for Firebase and Firebase Predictions to target based on user profile data, current behavior, or predicted churn risk. _Teams rolling out in-app engagement features can track Firebase product changes like this on daily.dev._ ### How many writes per second can Cloud Firestore handle after the scaling improvements announced at Cloud Next 2018? Cloud Firestore can scale up to 10,000 writes per second and support up to 1 million concurrent users after improvements announced at Cloud Next 2018. Alongside this, Cloud Functions for Firebase reached general availability with a service-level agreement, and both services planned to add new regions in Europe and Asia. _Developers planning serverless backend capacity can follow scaling milestones like this on daily.dev._ ### What is new in the Firebase CLI version 4.1.0 for Firebase Hosting deployments? Starting with version 4.1.0, the Firebase CLI only uploads files that changed since the last release when deploying to Firebase Hosting, rather than re-uploading the entire site. This speeds up deployment updates significantly, especially for larger sites, and complements a separate rollout allowing multiple websites to be hosted within a single Firebase project. _Anyone optimizing deploy speed for static sites can keep tabs on tooling updates like this via daily.dev._ --- Tags: [#mobile](https://daily.dev/tags/mobile), [#firebase](https://daily.dev/tags/firebase) [View this post on daily.dev](https://daily.dev/posts/in-app-messaging-crashlytics-integrations-and-more-oh-my--mrtruip6h) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"In-App Messaging, Crashlytics integrations, and more!
