Migration Guidance

Issue Description

MULE-9032

BouncyCastle was upgraded to version 1.54.

DESede algorithm now requires keys of 16 or 24 bytes unlike the prior version which required 16 or 22 bytes.

MULE-9337

TLSv1 is no longer listed as an enabled protocol, by default only TLSv1.1 and TLSv1.2 will be enabled.
If you wish to use TLSv1 you can edit the TLS configuration file (tls-default.conf) and add it back to the enabled protocols entry.

MULE-9501

The wildcard-filter will only work with prefix (.log), suffix (java.util.) or enclosing strings (util) patterns, as well as the deprecated payload based filter (java.lang.Throwable+) and regular strings.

In any other case no match will be possible, regardless of the input. The regex-filter should be used for other cases.

This also affects the wildcard patterns allowed by the file-wildcard-filter, request-wildcard-filter, expression-filter, message-property-filter, exceptions strategies commit-transaction and rollback transaction exception patterns, wildcard patterns used in expressions, among others (complete list can be found in MULE-9501).

Known Issues

Issue Description

MULE-9201

HTTP request should throw a ConnectException when it fails to send a request
