Custom Actions broken in Beta-3.3.0-3678

My custom actions are completely broken in the latest Beta-3.3.0-3678.

Following is just one example of many of my custom actions that no longer function. Custom actions have always been a bit screwy as can be seen by the fact I need to use this batch file (bashRunCmd.bat) to work around oddities with the way the parameters are passed.

This particular script just opens a command prompt window in Beta 3.3.0. It works fine in SourceTree for Windows 3.2.6.

Reflog
Script to run: C:\git\tools\bashRuncmd.bat
Parameters: C:\git\tools\git-merge-abort.sh $REPO

bashRuncmd.bat:
SET mypath=%~dp0
start "C:\Program Files\Git\git-bash.exe" %1 %2 %3 %4 %5

git-merge-abort.sh:
#!/bin/bash
git merge --abort

And by the way why can't you guys get this JIRA system figured out? The "Affects version/s" field contains a list of versions which doesn't even include the latest released versions.
The version I was forced to put in there is inaccurate.

1. Custom actions not displaying executions, nothing happens on click.
2. Custom action with multiple parameters are set .(In the parameter field, “$SHA  $FILE” was used.)  And right click on one file of one commit and choose custom action , but  the custom action I made earlier with single parameter was NOT displayed.
