How can I convert this zig 0.9.0 build file into 0.11.0?

I have this zig 0.9.0 build file which does not work with 0.11.0. How can I migrate it to the 0.11.0?

const Builder = @import("std").build.Builder;
const builtin = @import("builtin");
const std = @import("std");

pub fn build(b: *Builder) void {

    // NOTE: STM32F407VG
    // NOTE: ZIG has definitions for .thumb, .freestanding, .eabihf...
    const target = .{
        .cpu_arch = .thumb,
        .cpu_model = .{ .explicit = &std.Target.arm.cpu.cortex_m4 },
        .os_tag = .freestanding,
        .abi = .eabihf,
    };

    // Standard release options allow the person running `zig build` to select
    // between Debug, ReleaseSafe, ReleaseFast, and ReleaseSmall.
    const mode = b.standardReleaseOptions();

    const elf = b.addExecutable("zig-stm32-blink.elf", "src/startup.zig");
    elf.setTarget(target);
    elf.setBuildMode(mode);

    const vector_obj = b.addObject("vector", "src/vector.zig");
    vector_obj.setTarget(target);
    vector_obj.setBuildMode(mode);

    elf.addObject(vector_obj);
    elf.setLinkerScriptPath(.{ .path = "src/linker.ld" });

    const bin = b.addInstallRaw(elf, "zig-stm32-blink.bin", .{});
    const bin_step = b.step("bin", "Generate binary file to be flashed");
    bin_step.dependOn(&bin.step);

    const flash_cmd = b.addSystemCommand(&[_][]const u8{
        "st-flash",
        "write",
        b.getInstallPath(bin.dest_dir, bin.dest_filename),
        "0x8000000",
    });
    flash_cmd.step.dependOn(&bin.step);
    const flash_step = b.step("flash", "Flash and run the app on your STM32F4Discovery");
    flash_step.dependOn(&flash_cmd.step);

    b.default_step.dependOn(&elf.step);
    b.installArtifact(elf);
}

Be sure to check out the 0.10.0 release notes and 0.11.0 release notes which should contain the answer.

That is probably the best place to check. Thank you Andrew!
