Upgrading to 5.7 and above from earlier versions is a little
problematic. Let's document it.

## About the changes
When edge is configured to automatically generate tokens, it requires
the token to be present in all unleash instances.
It's behind a flag which enables us to turn it on on a case by case
scenario.
The risk of this implementation is that we'd be adding load to the
database in the middleware that evaluates tokens (which are present in
mostly all our API calls. We only query when the token is missing but
because the /client and /frontend endpoints which will be the affected
ones are high throughput, we want to be extra careful to avoid DDoSing
ourselves
## Alternatives:
One alternative would be that we merge the two endpoints into one.
Currently, Edge does the following:
If the token is not valid, it tries to create a token using a service
account token and /api/admin/create-token endpoint. Then it uses the
token generated (which is returned from the prior endpoint) to query
/api/frontend. What if we could call /api/frontend with the same service
account we use to create the token? It may sound risky but if the same
application holding the service account token with permission to create
a token, can call /api/frontend via the generated token, shouldn't it be
able to call the endpoint directly?
The purpose of the token is authentication and authorization. With the
two tokens we are authenticating the same app with 2 different
authorization scopes, but because it's the same app we are
authenticating, can't we just use one token and assume that the app has
both scopes?
If the service account already has permissions to create a token and
then use that token for further actions, allowing it to directly call
/api/frontend does not necessarily introduce new security risks. The
only risk is allowing the app to generate new tokens. Which leads to the
third alternative: should we just remove this option from edge?

A v1 Java tutorial for docs! I used Java SDK to log flag statuses when
the Java app is running and connected to Unleash.

It's fairly simple and open to feedback for a new iteration to improve
the intro tutorial. I do weekly documentation improvement PRs!
I've held an internal knowledge sharing session on this already. If
someone can think of a better phrasing for the background, I'm all ears.
I think it's just nice to have this documented, so people remember that
our logging framework already has a good way to format errors when you
use the API `logger.error("<message>", e)`
Fixes ##5799 and #5785
When you do not provide a token we should resolve to the "default"
environment to maintain backward compatibility. If you actually provide
a token we should prefer that and even block the request if it is not
valid.
An interesting fact is that "default" environment is not available on a
fresh installation of Unleash. This means that you need to provide a
token to actually get access to toggle configurations.

Having old ADRs makes it harder for newcomers, that have to navigate
through many ADRs and spot the ones that were superseded by others. We
can save the mental burden by just moving the old ones to a deprecated
folder
This change updates the change request scheduling docs to include
information about what happens when a strategy or segment is updated
in the background, as well as updated information about the emails
that it sends out.
This PR updates the images in the feature flags best practices guide to
work on dark backgrounds by giving them white backgrounds (making them
non-transparent).
In doing so, it replaces the links to GitHub with docusaurus assets
(which also yields faster loading) and uses captions to describe the
images.
This change hides the quickstart and doc nav bar links when you're on
the docs pages.
This gets around the issue of both of those links being
highlighted when you're on the docs pages.
This should work on 91.66% of browsers (according to [canIUse's data for
the `:has` selector](https://caniuse.com/?search=%3Ahas)). For older
browsers, the links will still be visible.
So we have a place in the docs to refer users struggling with getting
metrics from Edge after upgrade to Unleash v5.9.0, this PR adds a small
troubleshooting note about two fixes.
1. Upgrade Edge
2. Use environmental flag to re-enable old endpoint

A new Python Examples doc:
- underneath Python tutorials
- explores more use cases for Python with feature flags in Unleash,
building on top of our existing Python tutorial.

This PR cleans up the the CSS for the recent academy banners, sharing
styles where it seemed suitable.
Main points:
- share styling of the level badge between the links and the course
banner
- share styling of general banner shape, borders, spacing, between the
main unleash academy banner and the course-specific banner
Also does the following updates:
- change the button colors
- update the link in the main academy banner

- Reducing the amount of steps to implement the Python app feature flag
- fixed spaces & indentations in Python code snippets (mentioned in past
PR review)
- `git clone` my forked repo so we can customize that code in the future
as we improve it, without being blocked.

More improvements to be made to the HTTP calls in `routes.py` as I

This PR fixes the three issues in the nav bar:
1. The GitHub icon was rendered in black in light mode. It should be
white.
2. The toggle theme button's background was white in light mode. It
should be a darker green.
3. The navbar would intersect with the logo due to not compacting
correctly.
The first two issues were caused by using CSS nesting, which is
apparently not supported in Safari yet (and might only be supported if
you have enabled a flag in other browsers).
The last issue was fixed by changing the syntax of a media query. The
new syntax is unsupported in Safari.
## Key Updates in the ADR
- **Separation of Migrations in PRs**: Migrations are now required to be
carried out in separate pull requests. This change is intended to
improve the monitoring and management of database schema changes during
deployment.
- **Primary Key Requirement for New Tables**: A new paragraph mandates
the inclusion of primary keys in all new tables, emphasizing the
importance of data integrity, efficient data retrieval, and supporting
table relationships. Additionally, by adding primary keys, we resolve
the issue of migrations failing during upgrades in replicated database
setups, as we are not using PostgreSQL replica identities. Exceptions to
this rule require a compelling justification.
Also added better structuring and styling to ADR for better readability.
Update the Unleash docs navbar according to the new spec:
Changing "estimated time burden" to "estimated time" (or "estimated
reading time"), is just a matter of changing the text in the files.
There's nothing special making it say burden other than plain text. That
can be done in a follow-up PR.
The new nav bar includes the Unleash academy and certification dropdowns
as well as the docs and quickstart items. On smaller screen sizes
(between 997 and 1150 px), we hide the word "Unleash" from "Unleash
academy" and "Unleash certification".
The narrowest nav bar:

Let's update our tutorial titles in the left navigation menu so it's
shorter and simpler.
This will _not_ change the metadata and doc titles when you click on
them. Only the label in the nav.

A new tutorial to get developers to implement feature flags into a
Python Flask app.
We have steps that guide them through the process using a simple
full-stack survey app.
Based off of a reviewed [Google Doc
here](https://docs.google.com/document/d/1YlG-TyQcMEyUrMjiWlYrd-J5DXog5ErbvSKAyuzKAnU/edit#heading=h.ryvmv14764i3)
The tutorial can go live in the docs nav in a new Python section, where
the Python examples will follow.
