We've all been asked time and time again to refrain from doing so.

so, check it out.

A few clarifications before I crash with another headache:
Code Factory add-ons: while I cannot go into specifics, there was a
last minute change made in NVDA 2022.1 to keep many add-ons
compatible (specifically, control types refactor). I'm not sure if
Code Factory is referring to this issue (a while ago someone posted
that CF told folks that they are awaiting word from NV Access about
code change in 2022.1), but I imagine that folks over there are
working on compatibility updates.
Add-on update delays: it is normal to receive compatibility updates
with a delay when stable NVDA versions are released, more so when we
have a year.1 version (compatibility breaking release) in front of
us. Without going into details, around the time NVDA 2022.1 beta 1
was around the corner, add-on authors wrote to NV Access about
control types refactor (see the list archive from last year for an
overview from me about this) and that can break more add-ons than
anticipated. Therefore, NV Access decided to include a compatibility
layer for old and new add-on releases, which is why add-ons may
appear to work when you edit the manifest (addressed below). But for
all practical purposes, NV Access recommends using the new control
types code introduced in NVDA 2021.2.
As for manifests, as you read from Brian V a few minutes ago, working
with manifests is a temporary workaround until the actual update
declaring compatibility with the just released NVDA version becomes
available. Why is this method a temporary workaround?
1. 32-bit versus 64-bit Python: the reason why NVDA is a 32-bit
application (for the most part) is because it is running on top
of a 32-bit Python interpreter. There has been talks about moving
to 64-bit Python (and consequently making NVDA a 64-bit screen
reader), which requires a huge coordination between NV Access,
add-ons community, users, and other stakeholders - similar to, or
more than the work required to move from Python 2 to Python 3 (by
the way, as of May 2022, building add-ons with Python 2 is no
longer supported). Moving from 32-bit to 64-bit is not a simple
matter of instaling a 64-bit Python interpreter and get it to run
NVDA - it requires working with dependencies, including
third-party libraries which can come in either 32-bit or 64-bit
flavors, or in some cases, libraries needed to let 64-bit NVDA
talk to 32-bit components and programs. Add-ons are not free from
this - I would say add-ons require more work than the screen
reader itself as they can come with components that are purely
32-bit (most notable being 32-bit speech synthesizer DLL's); on
64-bit Windows, you CANNOT let a 64-bit executable (.exe) talk to
32-bit DLL and vice versa without asking someone (another
executable) to serve as a bridge and translate things on the fly
(won't go into details as it is quite technical (low-level,
literally) and don't want to go to the hospital right now). This
becomes more important if your favorite add-on(s) use Python
libraries with the extension of .pyd (Python extension DLL), and
recent Python releases will load compatible DLL's (32-bit pyd for
32-bit Python and vice versa). So imagine a scenario where a
64-bit NVDA is released and you edit the add-on manifest,
thinking that your favorite add-on(s) will work beautifully on
both 32-bit and 64-bit NVDA. I'll leave it up to you to imagine
what would happen when you restart NVDA.
2. NVDA code can come and go: while the biggest under the hood
change in NVDA 2022.1 (among other things) is control types
refactor, there are things that can be introduced in future NVDA
(and Python) releases that can make add-ons inoperable without
editing the add-on source code. Imagine a new version of NVDA is
released which is powered by a newer Python release (say, 3.10).
Even if the add-on manifest edits appear to work and the add-on
source code looks fine, it may not work correctly if it turns out
it is using parts of Python that is no longer present or changed
in some way. This becomes complicated if the add-on uses pyd
files - Python will load pyd files that are compatible with: the
version of Python you have and bit compatibility (32-bit Python
3.7 will load pyd files specifically designed for 32-vbit Python
The biggest takeaway: EDIT MANIFESTS AS A LAST RESORT OPTION! Or, for
that matter, DO NOT EDIT MANIFESTS, or if you must do it, first
contact the add-on author BEFORE following what Brian wrote to you
several minutes ago.
P.S. I once thought about instructing Add-on Updater (in the future)
to present a message to anyone using add-ons with modified manifests
but decided against as it is draconian and requires Internet access.
But my sentiment remains: unless you know what you are doing, editing
manifests should not be attempted prior to doing everything you can
to contact the add-on author about updates. After all, it is not NV
Access who has final authority on add-ons - the ultimate authority
with add-ons rest with authors (including NV Access if they wrote
add-ons you are using); my statement on who has final (and ultimate)
authority on add-ons should also answer a question posed earlier: who
to call when add-ons become unmaintained (contact the last known
maintainer and/or the original add-on author (contact info can be
found in Add-ons Manager) and then let the community know).
P.S. This might be the last time I will address this subject (for
now; NVDA 2022.1 development and coordinating add-on compatibility
while studying for grad seminars (which I passed, by the way) was
rewarding and stressful; I didn't feel this tired and out of energy
since 2016 while organizing NVDACon that year, ended up lying on my
bed for a few days then).
