I hope your new year is off to a great start! Instead of doing a usual round-up of my favorite news and articles from the past week or two, I thought it’d be fun to look back at 2017 at some of the amazing milestones that Kotlin has achieved over the past year. Let’s dive in!

Kotlin’s Achievements in 2017

• The book, Kotlin in Action hit bookshelves in February. Many of us see this book as the go-to resource for understanding the language beyond the online documentation, as it was written by members of the Kotlin team.¹
• Kotlin 1.1 was released in March, graduating the JavaScript target out of experimental status, and introducing coroutines.
• Kotlin 1.1.1 - 1.1.60 were released from March to November. (Since the build numbering system changed, note that this is not actually sixty releases…) ;)
• Kotlin/Native was introduced as a tech preview in April.
• At Google I/O, they announced official support for Kotlin on Android in May! This was a huge boost for the popularity of the language, and we’ve seen tons of online Android tutorials moving from Java to Kotlin.
• In November, Kotlin’s first conference, KotlinConf, launched with over 1200 attendees, and lots of outstanding presentations from the JetBrains team and from others in the community.
• Also in November, Kotlin 1.2 was released with a focus on developing across different platforms and sharing code among them. Kotlin throughout the full stack!
• At the end of December, Kotlin’s new official coding conventions document was published.

Wow! That’s a lot. With all of this activity, we saw the language jump ranks from 89 to 39 year-over-year in the TIOBE index. Congratulations to the JetBrains team and to the Kotlin community for a fantastic year!

Did I miss anything?

I’m sure I did! There’s been so much that happened with Kotlin over the past year that I probably missed some milestones. If you’ve got some to share, reach out to me on Twitter or Kotlin Slack.
