post-02 branch cannot be built successfully

[lima2020-root]

Hi, I cannot build this branch successfully. My environment and error was listed as following:

❯ rustc --version --verbose
rustc 1.70.0-nightly (a266f1199 2023-03-22)
binary: rustc
commit-hash: a266f11990d9544ee408e213e1eec8cc9eb032b7
commit-date: 2023-03-22
host: aarch64-apple-darwin
release: 1.70.0-nightly
LLVM version: 15.0.7

the dependencies was set as

[package]
name = "blog_os"
version = "0.1.0"
authors = ["Philipp Oppermann <dev@phil-opp.com>"]
edition = "2021"

[dependencies]
bootloader = "0.11.2"

with #![no_std] is set in main.rs, running cargo build, this post-02 still tries to find some dependencies and types, like

The post-02 branch uses bootloader 0.9.8, not 0.11.2. The current second edition of blog os doesn't work with bootloader >0.9 as 0.10 and 0.11 use a fundamentally different way of integration. @phil-opp is currently working on a third edition which will use bootloader 0.11.
