Add a note on the issue #5953
Hello,
I thought it would be better to have a note and warning about this issue considering it introduced an UB in the past even with the "Search on Github" feature.

changelog: Add a note on the issue #5953 to the known problems section.
Deprecate `filter_map`
Since #6591, `filter_map` does not even lint `filter().map()`. The cases that are still linted make no sense IMO. So this just removes/deprecates it.

Fix FP in `single_component_path_imports` lint
Fix FP in `single_component_path_imports` lint when the import is reused with `self`, like in `use self::module`.

Fix false-positive `debug_assert` in `panic`
This fixes a false-positive in `clippy::panic` when `debug_assert` is used with a message.
Fixes https://github.com/rust-lang/rust-clippy/issues/7062.

Remove `debug_assert` from `panic_in_result_fn`
I couldn't find any documentation on `debug_assert` that should be remove.
In my humble opinion, I would also like to argue that `todo` and `unreachable` shouldn't trigger this lint?

Use `register_renamed` instead of `register_removed` for uplifted lints
This still applies the lint, and also adds a structured suggestion to
rename it.

Invalid null usage v2
This is continuation of #6192 after inactivity.
I plan to move paths into the compiler as diagnostic items after this is merged.

Use AnonConst for asm! constants
This replaces the old system which used explicit promotion. See #83169 for more background.
The syntax for `const` operands is still the same as before: `const <expr>`.
Fixes#83169
Because the implementation is heavily based on inline consts, we suffer from the same issues:
- We lose the ability to use expressions derived from generics. See the deleted tests in `src/test/ui/asm/const.rs`.
- We are hitting the same ICEs as inline consts, for example #78174. It is unlikely that we will be able to stabilize this before inline consts are stabilized.
Fix all occurences `needless_borrow` internally
The bug that got 'needless_borrow' moved into the nursery was fixed two years ago in d4370f8b.
This did trigger over a thousand times internally, so that's all the other changes. I vetted most of them, but there's a lot The only interesting change is to the lint list. `declare_tool_lint` already makes a reference, so there's no need to take a reference to the lints.

consider mutability on useless_vec suggestions
fixes#7035
changelog: Now the suggested by `useless_vec` considers mutability to suggest either `&[]`, as before, or `&mut []` if the used reference is mutable.
This is a quick-fix for an ICE in `tabs_in_doc_comments`. The problem
was that we we're indexing into possibly multi-byte characters, such as '位'.
More specifically `get_chunks_of_tabs` was returning indices into
multi-byte characters. Those were passed on to a `Span` creation that
then caused the ICE.
This fix makes sure that we don't return indices that point inside a
multi-byte character. *However*, we are still iterating over unicode
codepoints, not grapheme clusters. So a seemingly single character like y̆ ,
which actually consists of two codepoints, will probably still cause
incorrect spans in the output.
Don't trigger `same_item_push` if the vec is used in the loop body

New Lint: `branches_sharing_code`
This lint checks if all `if`-blocks contain some statements that are the same and can be moved out of the blocks to prevent code duplication. Here is an example:
```rust
let _ = if ... {
println!("Start"); // <-- Lint for code duplication
let _a = 99;
println!("End"); // <-- Lint for code duplication
false
} else {
println!("Start");
let _b = 17;
println!("End");
false
};
```
This could be written as:
```rust
println!("Start");
let _ = if ... {
let _a = 99;
false
} else {
let _b = 17;
false
};
println!("End");
```
---
This lint will get masked by the `IF_SAME_THEN_ELSE` lint. I think it makes more sense to only emit one lint per if block. This means that the folloing example:
```rust
if ... {
let _a = 17;
} else {
let _a = 17;
}
```
Will only trigger the `IF_SAME_THEN_ELSE` lint and not the `SHARED_CODE_IN_IF_BLOCKS` lint.

Remove author requirement for `cargo_common_metadata`
This PR follows https://github.com/rust-lang/cargo/pull/9282, I'm not fully informed about all of this, it would be great if somebody knowledgeable about this topic agrees.
changelog: Changed `cargo_common_metadata` to stop linting on the optional author field.
