Neovim 0.13

Neovim 0.13 hit the streets in mid-September 2026, and it is all about windows, sessions, and buffers. Here is the rundown.

Window Wins

• :detach! - The new detachment command lets you pull a window out of the current layout and manage it on its own terms.
• Refined window handling - Improvements to how splits and floating windows behave during complex layout operations.

Session Serenity

Sessions get noticeably more capable in this release, addressing long-standing complaints about saving and restoring editor state across restarts. If you live by session managers, 0.13 makes the built-in behavior harder to justify replacing.

Buffer Benefits

Buffer management received a round of polish, with cleaner semantics around unnamed and scratch buffers. The changes reduce surprises when buffers move between windows.

Upgrade at Your Own Pace

For most setups the migration is turnkey. Plugin authors should scan the Neovim news docs for behavior changes around windows before the next minor lands. Do not delay the update, but do test your window-heavy workflows first.
