+# Release 3.16.0 (2026-02-12)
+
+* Based on [upstream Nix 2.33.3](../release-notes/rl-2.33.md).
+
+## Support `.gitattributes` in subdirectories
+
+For performance, the Git backwards compatibility hack was only applied to repositories that had a `.gitattributes` in the root directory.
+However, it is possible to have a `.gitattributes` file in a subdirectory, and there are real-world repos that do this, so we have dropped that restriction.
+
+PR: [DeterminateSystems/nix-src#335](https://github.com/DeterminateSystems/nix-src/pull/335)
+
+## Fix hung downloads when `http-connections = 0`
+
+When we started limiting the number of active cURL handles in [DeterminateSystems/nix-src#315](https://github.com/DeterminateSystems/nix-src/pull/315), we did not take into account that `http-connections = 0` is a special value that means, roughly "as many connections as possible" (the exact behavior is up to cURL).
+
+This should now be fixed.
+
+PR: [DeterminateSystems/nix-src#327](https://github.com/DeterminateSystems/nix-src/pull/327)
+
+## `builtins.getFlake` now supports relative paths
+
+`builtins.getFlake` now supports using relative paths, like:
+
+```nix
+builtins.getFlake ./..
+```
+
+instead of the hacky
+
+```nix
+builtins.getFlake (builtins.flakeRefToString { type = "path"; path = self.sourceInfo.outPath; narHash = self.narHash; });
+```
+
+Note that allowing `builtins.getFlake` to fetch from store paths is probably a bad idea, since it's ambiguous when using chroot stores, so a warning will be printed when this is encountered.

+
+## Fixed a bug with too many open files
+
+Recently, some users have reported seeing errors like:
+
+```
+error: creating git packfile indexer: failed to create temporary file '/Users/anon/.cache/nix/tarball-cache-v2/objects/pack/pack_git2_56d617039ac17c2b': Too many open files
+```
+
+This should now be fixed.
