This release of Flow comes with some great new features, bugfixes and a lot of modernisation of the existing code base.
As usual, we worked hard to keep this release as backwards compatible as possible but, since it’s a major release, some of the changes might require manual adjustments. So please make sure to carefully read the upgrade instructions below.
FEATURE: Add method askQuestion to console output that accepts a Question object
The other question methods take arrays or strings as arguments which is easy and convenient however the underlying symfony console offers more flexibility.
This pr adds the method
askQestion that accepts a smfony console question object and thus allows the full flexibility at the price of complexity.
In addition the method
getQuestionHelper is made public to make this as accessible as the
I chose not to allow Question objects in the
ask method because this method has a default argument that only makes sense when the question is passed as array or string.
FEATURE: typed env variable replacements in Settings
With this change, the type of environment variables can be specified in Configuration files:
This will cast the corresponding value to the specified type (and to the base value of the type when referring to undefined environment variables).
Supported types and their base value are:
string: “” (empty string)

FEATURE: Support object serialization without var annotation
This change introduces support for PHP 7.4 style class property
type declarations for objects to be serialized by Flow. Previously,
@var annotation had to be specified for each class property, in
order to communicate the type to Flow’s serialization mechanism.

This section contains instructions for upgrading your Flow 8.0 based applications to Flow 8.1.
In general just make sure to run the following commands:
To clear all file caches:
./flow flow:cache:flush --force
If you have additional cache backends configured, make sure to flush them too.
To apply core migrations:
./flow flow:core:migrate <Package-Key>
For every package you have control over (see Upgrading existing code below).
To validate/fix the database encoding, apply pending migrations and to (re)publish file resources:
If you are upgrading from a lower version than 8.0, be sure to read the upgrade instructions from the previous Release Notes first.
Upgrading existing code
There have been major API changes in Flow 8.1 which require your code to be adjusted. As with earlier changes to Flow that required code changes on the user side we provide a code migration tool.
Given you have a Flow system with your (outdated) package in place you should run the following before attempting to fix anything by hand:
./flow core:migrate Acme.Demo
This will adjust the package code automatically and/or output further information. Read the output carefully and manually adjust the code if needed.
To see all the other helpful options this command provides, make sure to run:
./flow help core:migrate
Also make sure to read about the `Potentially breaking changes`_ below.
The tool roughly works like this:
Collect all code migrations from packages
Collect all files from the specified package
For each migration
Check for clean git working copy (otherwise skip it)
Check if migration is needed (looks for Migration footers in commit messages)
Apply migration and commit the changes
Afterwards you probably get a list of warnings and notes from the migrations, check those to see if anything needs to be done manually.
Check the created commits and feel free to amend as needed, should
things be missing or wrong. The only thing you must keep in place from
the generated commits is the migration data in
composer.json. It is
used to detect if a migration has been applied already, so if you drop
it, things might get out of hands in the future.
