Presto 10.14 New! Full.16 Guide
Since no additional context (software type, publisher, platform) was provided, I’ve structured this as a general software review for a hypothetical major version release.
Operational Predictability: The Underrated Virtue
Perhaps the most understated improvement in 10.14 Full.16 was memory management. Prior versions occasionally suffered from "over-commit" spills, where a single heavy query would destabilize a worker node. This release refined the memory pool arbiter, introducing a fair-sharing policy that throttles aggressive queries before they trigger OOM (out-of-memory) errors. Additionally, the web UI gained more intuitive query timeline visualizations, allowing administrators to pinpoint bottlenecks without parsing dense logs. These changes might seem mundane, but for teams running Presto in production, they transform a powerful engine into a reliable workhorse. Presto 10.14 Full.16

Pretty sure it's chrome that's built in. Remember having to install Firefox from desktop mode.
Unless something changed recently, Firefox was always built in. They did make it so you have to install it manually a year or so after initially launching, but Chrome was never included.
Firefox is built-in with the desktop mode. I believe when first going to "Non-Steam Games" in Gaming Mode, SteamOS does prompt you to install Chrome as Chrome plays nicer in Gaming Mode.
