Apollo Client 1.0 is a significant release that builds upon the best features from the previous series, including seamless integration with various frameworks and support for GraphQL subscriptions. The new version includes several improvements, such as fine-grained cache reads and writes, simplified client API, and better defaults for query deduplication and network status changes. To ensure its success, the team is relying on the community's help, encouraging users to try it out, report bugs, write blog posts about their experiences, find edge-cases that break the software, and spread the word. The release marks the start of a new testing period before the official launch, during which the team will thoroughly test Apollo Client, collect feedback, and fix major bugs. After reaching 1.0, the development process will continue with new features and improvements.
