## Executive Summary (TL;DR)
Bun bun-v0.0.68. Source highlight: This release is mostly focused on bun.js, bun's JavaScript runtime environment. Fixes to `bun install` will be part of the next release, but the infrastructure work from this release will help with `bun install` in the next release.

## Bug Fixes
- If bun exits due to running out of file descriptors, bun will print some platform-specific instructions explaining how to fix it.
- Fixed a couple regressions that caused bun to start up slower, now it's back to about 3.5ms on macOS aarch64 and 0.5ms on linux amd64
- Fixed a bug in the upgrade checker that would sometimes cause bun to crash, typically after about 30 seconds
