Flow 7.3
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.
New Features
FEATURE: Make backtrace code expandable with HTML5 <summary> element
The backtrace code is printed when the DebugExceptionHandler is active (in “Development” context).
This can be quite a mouthful for new users and developers. The backtrace go all the way back to the Flow Bootstrapping - things that are interesting when you get more into Flow.
This is changed, by using the HTML5 element <summary> element that support collapsing without any extra libraries or code

FEATURE: Add case-insensitive filter operators for FlowQuery
I added case-insensitive filter operators for FlowQuery
ExactMatchInsensitive: =~ NotEqualMatchInsensitive: !=~ SuffixMatchInsensitive: $=~ PrefixMatchInsensitive: ^=~ SubstringMatchInsensitive: *=~ ````
I extended the FilterOperation Class. Also I extended the Fizzle.peg.inc and compiled the FizzleParser.php with generateEelParser.sh.
I extended the related tests for FizzleParser and FlowQuery. And run the test. Both have passed.
FEATURE: CLI command to list all connected signals with their slots
The CLI command lists all signals with their slots. As parameter it accepts the class name and method name of the signal to filter the output.
Help output: ``` Lists all connected signals with their slots.

Upgrade Instructions
This section contains instructions for upgrading your Flow 7.2 based applications to Flow 7.3.
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:
./flow database:setcharset
./flow doctrine:migrate
./flow resource:publish
If you are upgrading from a lower version than 7.2, be sure to read the upgrade instructions from the previous Release Notes first.
Upgrading existing code
There have been major API changes in Flow 7.3 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.
