You can either:
a) switch to individual clones of bitbake, openembedded-core, meta-yocto and yocto-docs
b) use the new bitbake-setup
You can find information about either approach in our documentation:
https://docs.yoctoproject.org/
Note that "poky" the distro setting is still available in meta-yocto as
before and we continue to use and maintain that.
Long live Poky!
Some further information on the background of this change can be found

Currently, class extensions are implmented using shadow variables and
access indirection which is horribly ineffient and ugly.
Switch to using the new bitbake filter API, which allows a translation
of the variable before the expanded value is returned. This allows us
to drop the shadow variable accesses. It also avoids the need to iterate
PACKAGES and make many variable changes since a filter against RDEPENDS
applies to RDEPENDS:${PN} and all of it's other overridden values.
Since data expansion happens at access, it also avoids many of the race
conditions this code has tranditionally been plagued with.

This implements the following base ISAs:
* rv32i, rv64i
* rv32e, rv64i
The following ABIs:
* ilp32, ilp32e, ilp32f, ilp32d
* lp64, lp64e, lp64f, lp64d
The following ISA extension are also implemented:
* M - Integer Multiplication and Division Extension
* A - Atomic Memory Extension
* F - Single-Precision Floating-Point Extension
* D - Double-Precision Floating-Point Extension
* C - Compressed Extension
* B - Bit Manipulation Extension (implies Zba, Zbb, Zbs)
* V - Vector Operations Extension
* Zicsr - Control and Status Register Access Extension
* Zifencei - Instruction-Fetch Fence Extension
* Zba - Address bit manipulation extension
* Zbb - Basic bit manipulation extension
* Zbc - Carry-less multiplication extension
* Zbs - Single-bit manipulation extension
* Zicbom - Cache-block management extension
The existing processors tunes are preserved:
* riscv64 (rv64gc)
* riscv32 (rv32gc)
* riscv64nf (rv64imac_zicsr_zifencei)
* riscv32nf (rv32imac_zicsr_zifencei)
* riscv64nc (rv64imafd_zicsr_zifencei)
Previously defined feature 'big-endian' has been removed as it was not used.

Move the functions in qemu.bbclass to meta/lib/oe/qemu.py as they are
generally useful.
The qemu.bbclass is still kept, and recipes can continue to use functions
from it, though they have become wrapper functions on qemu.py functions.
Note that the QEMU_OPTIONS settings are still kept in qemu.bbclass.
This sets a clear barrier for people to use qemu user mode.

Adds cve_check.py to BBIMPORTS so the functions it exposes will be

The SPDX library code was being ignored from taskhash calculations due
to accidentally being omitted from BBIMPORTS. This meant that changes in
the code or dependent variables would not cause the task to rebuild
correctly.
In order to add spdx_common, convert the `Dep` object from a named tuple
to a frozen dataclass. These function more or less equivalently, but the
bitbake code parser cannot handle named tuples.
Finally, the vardepsexclude that used to be present on the recipe tasks
needs to be moved to the python code in order for the variables to be
correctly ignored. Several unused exclusions were removed

Early functions like do_recipe_qa (which do_fetch depends upon) reference
oe.qa.handle_error() which in turn adds dependencies on ERROR_QA and
WARN_QA. This means that ERROR_QA:append = " nothing" will cause
literally everything to rebuild and break sstate reuse.
Take advantage of new bitbake functionality to add a custom visitorcode
function to handle_error which optimises the references into contains
expressions which means the ERROR_QA and WARN_QA references are optmised
to containing specific strings. This dramatically improves sstate reuse.
The qa module has to be imported first since other code in later modules
references it and bitbake can't handle the dependency ordering internally
without a lot of unwanted complexity.

Other spaces uses the Go architecture definitions as their own (for
example, container arches are defined to be Go arches). To make it
easier for other places to use this mapping, move the code that does the
translation of OpenEmbedded arches to Go arches to a library.

Variable dependencies for functions in the oe.packagedata module were
missing as it was not present in BBIMPORTS. Add it as the fact it was
missing is likely just historical oversight from base.bbclass history
and the dependencies are useful.
Add an exclusion to bitbake.conf to ensure BB_NUMBER_THREADS doesn't
change task checksums.

Since bitbake now supports an official method to inject python modules,
switch to it.
Anyone using OE_EXTRA_IMPORTS will need to adjust their code accordingly,
probably switching to their own module namespace.
Also switch to using BB_GLOBAL_PYMODULES to list the global modules
to import.

Where there isn't a copyright statement, add one to make it explicit.

This adds SPDX license headers in place of the wide assortment of things
currently in our script headers. We default to GPL-2.0-only except for the
oeqa code where it was clearly submitted and marked as MIT on the most part
or some scripts which had the "or later" GPL versioning.
The patch also drops other obsolete bits of file headers where they were
encoountered such as editor modelines, obsolete maintainer information or
the phrase "All rights reserved" which is now obsolete and not required in
copyright headers (in this case its actually confusing for licensing as all
rights were not reserved).
More work is needed for OE-Core but this takes care of the bulk of the scripts
and meta/lib directories.
The top level LICENSE files are tweaked to match the new structure and the
SPDX naming.

This will let folks extend the oe package with modules from other layers.
Given openembedded consists of more than just oe-core, I think this makes
sense, and adds some useful flexibility.
