June 19, 2025 – Nintendo has quietly released system firmware version 20.1.5 for both the original Switch and the brand-new Switch 2, delivering what’s described as “general system stability improvements” to enhance the user experience.
🎮 What’s Included in 20.1.5?
| Platform | Key Details |
|---|---|
| Switch 1 | – Update installs automatically or via System Settings. Atmosphere CFW users confirm that the latest version of Atmosphere works without needing an update. |
| Switch 2 | – As a stability-focused release, it may also include compatibility fixes. Some previously buggy Switch 1 titles now run more smoothly on the Switch 2. |
⚠️ Note for CFW Users: Some homebrew communities are advising users to delay updating, as Atmosphere and other tools may not yet be fully compatible with 20.1.5.
🛠️ Why It Matters
Nintendo’s latest firmware is part of a series of updates released over the past few months, each aimed at improving system stability and user experience. Most users can update via System Settings → System → System Update.

🧭 Should You Update?
- Standard Users: Recommended. The update provides increased stability and potential performance improvements.
- Custom Firmware (CFW) Enthusiasts: Wait until compatibility with 20.1.5 is confirmed, as updating prematurely could block access to homebrew tools or exploits.
🔍 Bottom Line
Firmware 20.1.5 brings modest but meaningful enhancements to both the Switch and Switch 2. While standard users should have no issues updating, those using custom firmware should hold off for now. Nintendo has not published detailed patch notes, but the update is believed to offer game and system-level improvements.
