 ### Changed
 
 - **Zig pin is 0.17.0.** Replaces `0.17.0-dev.269+ebff43698` now that 0.17.0
   is the stable with the macOS 26 SDK fix the nightly was taken for.
   `mix mob.doctor` / `mix mob.deploy --native` still require an exact
   `zig version` match. Companion to mob and mob_new.
+- **Requires mob `~> 0.9.26`.** mob 0.9.25's Android NIF doesn't compile on
+  Zig 0.17.0 (it calls `std.fmt.bufPrintZ`, which 0.17.0 removed).
 
 ### Fixed
 
 - **`mix mob.doctor` checks the iOS Swift glob for Zig 0.17.0.** It fails
   `ios/build.zig` / `ios/build_device.zig` that still use `b.build_root`,
-  which 0.17.0 removed (configure panics with `no field named
-  'build_root'`). It warns when the glob opens `mob/ios` without
+  which 0.17.0 removed (configure fails with `error: no field named
+  'build_root' in struct 'Build'`). It warns when the glob opens `mob/ios` without
   `b.dependOnDirectoryContents`: 0.17.0 caches the configure phase, so a
   Swift file mob adds is missed until the zig cache is cleared. Comments and
   strings are ignored. The fix names mob_new's template block.

-- **Zig 0.17.0.** In each app, set `zig 0.17.0` in `.tool-versions`
+- **Zig 0.17.0, with mob 0.9.26.** mob_dev now requires `mob ~> 0.9.26`:
+  mob 0.9.25's Android NIF calls `std.fmt.bufPrintZ`, which Zig 0.17.0

   (`mise use zig@0.17.0` installs it and edits the file; `mise install
   zig@0.17.0` alone leaves the app on the nightly, and the native build
   rejects it). Existing iOS apps must port the Swift glob in
