The company's team expanded to 56 employees by the end of the year, moving to new offices in San Francisco and Austria. To improve efficiency, Sentry adopted a sprint process, created goal-oriented teams, and hired its first project manager. In terms of features, the company released numerous updates, including official support for React Native, improved releases, and new resolution tools. Sentry also invested heavily in its tools, infrastructure, and practices, adopting new technologies such as Jest, Enzyme, and Prettier.
