The MongoDB Node.js team released version 3.3.0 of their driver, with the highlight being version 4.2 server support. That means the driver can handle distributed transactions, On-Demand Materialized Views, Wildcard Indexes, retryable reads and supports the other enhancements made to the MongoDB Query Language including pipeline enabled updates.
Also included in the 3.3.0 driver is the enhanced SRV polling mechanism for sharded clusters. This feature allows applications that connect to a sharded cluster using SRV records to automatically update their knowledge of the clusters topology while running, rather than only on startup.
Internally, what was a two part driver - a low-level mongodb-core and a high-level node-mongodb-native - have now been merged with mongodb-core absorbed by node-mongodb-native. This merger should help speed up the development process of delivering the latest in MongoDB Node.js support.
Going in MongoDB 4.2
There's a lot going into MongoDB 4.2, like on-demand materialized views, pipeline powered updates and distributed transactions. And as we cleared the way for those new features, so we moved on and various commands and options that were previously deprecated are now completely removed. Find out what here.
Hear From the MongoDB World 2022 Diversity Scholars
The MongoDB Diversity Scholarship program is an initiative to elevate and support members of underrepresented groups in technology across the globe. Scholars receive complimentary access to the MongoDB World developer conference in New York, on-demand access to MongoDB University to prepare for free MongoDB certification, and mentorship via an exclusive discussion group. This year at MongoDB World, our newest cohort of scholars got the opportunity to interact with company leadership at a luncheon and also got a chance to share their experience in a public panel discussion at the Community Café. Hear from some of the 2022 scholars, in their own words.

We need like-minded individuals in our society even in this fourth industrial revolution, and we are not leaving anyone behind. Video: Watch the panel in its entirety Raja Adil, Student at Cal Poly SLO Currently, I am a software engineer intern at Salesforce. I started self-teaching myself software development when I was a junior in high school during the COVID-19 pandemic, and from there I started doing projects and gaining as much technical experience as I could through internships. Before the pandemic I took my first computer science class, which was taught in C#. At first, I hated it as it looked complex. Slowly, I started to enjoy it more and more, and during the pandemic I started learning Python on my own. I feel blessed to have found my path early in my career. What was your most impactful experience as part of the Diversity Scholarship? My most impactful experience was the network and friends I made throughout the four days I was in New York for MongoDB World. I also learned a lot about the power of MongoDB, as opposed to relational databases, which I often use in my projects. How has the MongoDB World conference inspired you in your learning or your career path? The MongoDB World conference was amazing and has inspired me a ton in my learning path. I definitely want to learn even more about MongoDB as a database, and in terms of a career path, I would love to intern at MongoDB as a software engineer down the line.
