    Revision history:
 
+     3.10.0 (2026-07-17) Make NOB_SVLIT a bit more usable at compile-time (by @Arhcout)
+                         Add NOB_SVLIT_STATIC for when a compiler simply refuses to accept NOB_SVLIT() at compile-time (looking at you `cl.exe /TC`) (by @rexim)
       3.9.0 (2026-07-15) Add NOB_TODOF() and NOB_UNREACHABLEF()
                          Add NOB_SVLIT()
                          Add nob_bytes_for_utf8[] and nob_sv_utf8_len()
