+- <https://github.com/rust-lang/rust/issues/74976>: Add "--stage 1"
+  to the "./x.py doc" call to ensure the newly built compiler gets
+  used.

+
+- Leap 15.3 does not provide a suitable llvm-devel package, hence
+  explicitly require llvm9-devel. Details can be seen in the following
+  e-mail thread
+  <https://lists.opensuse.org/archives/list/factory@lists.opensuse.org/thread/ZQWAMG2VYBSI2BFM7G3H5YG26ALXWAOA/>
+
+-------------------------------------------------------------------
+Sun Jan  3 11:33:37 UTC 2021 - Manfred Hollstein <manfred.h@gmx.net>
+
+- Update to version 1.49.0
+  + Language
+  - Unions can now implement Drop, and you can now have a field in
+    a union with ManuallyDrop<T>.
+  - You can now cast uninhabited enums to integers.
+  - You can now bind by reference and by move in patterns. This
+    allows you to selectively borrow individual components of a type.
+    E.g.
+
+    #[derive(Debug)]
+    struct Person {
+        name: String,
+        age: u8,
+    }
+
+    let person = Person {
+        name: String::from("Alice"),
+        age: 20,
+    };
+
+    // `name` is moved out of person, but `age` is referenced.
+    let Person { name, ref age } = person;
+    println!("{} {}", name, age);
+  + Compiler
+  - Added tier 1* support for aarch64-unknown-linux-gnu.
+  - Added tier 2 support for aarch64-apple-darwin.
+  - Added tier 2 support for aarch64-pc-windows-msvc.
+  - Added tier 3 support for mipsel-unknown-none.
+  - Raised the minimum supported LLVM version to LLVM 9.
+  - Output from threads spawned in tests is now captured.
+  - Change os and vendor values to "none" and "unknown" for some targets
+  * Refer to Rust's platform support page for more information on Rust's
+    tiered platform support.
+  + Libraries
+  - RangeInclusive now checks for exhaustion when calling contains and
+    indexing.
+  - ToString::to_string now no longer shrinks the internal buffer in
+    the default implementation.
+  - ops::{Index, IndexMut} are now implemented for fixed sized arrays
+    of any length.
+  + Stabilized APIs
+  - slice::select_nth_unstable
+  - slice::select_nth_unstable_by
+  - slice::select_nth_unstable_by_key
+  The following previously stable methods are now const.
+  - Poll::is_ready
+  - Poll::is_pending
+  + Cargo
+  - Building a crate with cargo-package should now be independently
+    reproducible.
+  - cargo-tree now marks proc-macro crates.
+  - Added CARGO_PRIMARY_PACKAGE build-time environment variable. This
+    variable will be set if the crate being built is one the user
+    selected to build, either with -p or through defaults.
+  - You can now use glob patterns when specifying packages & targets.
+  + Compatibility Notes
+  - Demoted i686-unknown-freebsd from host tier 2 to target tier 2
+    support.
+  - Macros that end with a semi-colon are now treated as statements
+    even if they expand to nothing.
+  - Rustc will now check for the validity of some built-in attributes
+    on enum variants. Previously such invalid or unused attributes
+    could be ignored.
+  - Leading whitespace is stripped more uniformly in documentation
+    comments, which may change behavior. You read this post about
+    the changes for more details.
+  - Trait bounds are no longer inferred for associated types.
+  + Internal Only
+  These changes provide no direct user facing benefits, but
+  represent significant improvements to the internals and overall
+  performance of rustc and related tools.
+  - rustc's internal crates are now compiled using the initial-exec
+    Thread Local Storage model.
+  - Calculate visibilities once in resolve.
+  - Added system to the llvm-libunwind bootstrap config option.
+  - Added --color for configuring terminal color support to bootstrap.

+- LLVM >= 9.0 is needed nowadays.
+- Disable usage of "ninja" for all distributions older than Leap 15.2
+
+-------------------------------------------------------------------
+Sat Jan  2 16:50:47 UTC 2021 - Manfred Hollstein <manfred.h@gmx.net>
+
+- Update to version 1.48.0
+  + Language
+  - The `unsafe` keyword is now syntactically permitted on modules.
+    This is still rejected semantically, but can now be parsed by procedural
+    macros.
+  + Compiler
+  - Stabilised the `-C link-self-contained=<yes|no>` compiler flag.
+    This tells `rustc` whether to link its own C runtime and libraries or to
+    rely on a external linker to find them. (Supported only on `windows-gnu`,
+    `linux-musl`, and `wasi` platforms.)
+  - You can now use `-C target-feature=+crt-static` on `linux-gnu` targets.
+    Note: If you're using cargo you must explicitly pass the `--target` flag.
+  - Added tier 2* support for aarch64-unknown-linux-musl.
+  * Refer to Rust's platform support page for more information on Rust's
+    tiered platform support.
+  + Libraries
+  - io::Write is now implemented for &ChildStdin &Sink, &Stdout, and &Stderr.
+  - All arrays of any length now implement TryFrom<Vec<T>>.
+  - The matches! macro now supports having a trailing comma.
+  - Vec<A> now implements PartialEq<[B]> where A: PartialEq<B>.
+  - The RefCell::{replace, replace_with, clone} methods now all use #[track_caller].
+  + Stabilized APIs
+  - slice::as_ptr_range
+  - slice::as_mut_ptr_range
+  - VecDeque::make_contiguous
+  - future::pending
+  - future::ready
+  The following previously stable methods are now `const fn's`:
+  - Option::is_some
+  - Option::is_none
+  - Option::as_ref
+  - Result::is_ok
+  - Result::is_err
+  - Result::as_ref
+  - Ordering::reverse
+  - Ordering::then
+  + Cargo
+  + Rustdoc
+  - You can now link to items in rustdoc using the intra-doc link syntax.
+    E.g. /// Uses [`std::future`] will automatically generate a link to
+    std::future's documentation. See "Linking to items by name" for more
+    information.
+  - You can now specify #[doc(alias = "<alias>")] on items to add search
+    aliases when searching through rustdoc's UI.
+  + Compatibility Notes
+  - Promotion of references to 'static lifetime inside const fn now
+    follows the same rules as inside a fn body. In particular, &foo()
+    will not be promoted to 'static lifetime any more inside const fns.
+  - Associated type bindings on trait objects are now verified to meet
+    the bounds declared on the trait when checking that they implement
+    the trait.
+  - When trait bounds on associated types or opaque types are ambiguous,
+    the compiler no longer makes an arbitrary choice on which bound to use.
+  - Fixed recursive nonterminals not being expanded in macros during
+    pretty-print/reparse check. This may cause errors if your macro
+    wasn't correctly handling recursive nonterminal tokens.
+  - &mut references to non zero-sized types are no longer promoted.
+  - rustc will now warn if you use attributes like #[link_name] or
+    #[cold] in places where they have no effect.
+  - Updated _mm256_extract_epi8 and _mm256_extract_epi16 signatures
+    in arch::{x86, x86_64} to return i32 to match the vendor signatures.
+  - mem::uninitialized will now panic if any inner types inside a struct
+    or enum disallow zero-initialization.
+  - #[target_feature] will now error if used in a place where it has no effect.
+  - Foreign exceptions are now caught by catch_unwind and will cause an
+    abort. Note: This behaviour is not guaranteed and is still considered
+    undefined behaviour, see the catch_unwind documentation for further
+    information.
+  + Internal Only
+    These changes provide no direct user facing benefits, but represent
+    significant improvements to the internals and overall performance of
+    rustc and related tools.
+  - Building rustc from source now uses ninja by default over make.
+    You can continue building with make by setting ninja=false in
+    your config.toml.
+  - cg_llvm: fewer_names in uncached_llvm_type
+  - Made ensure_sufficient_stack() non-generic
