Interchange 5.4.2

Interchange provides a mature Web application development environment.
Interchange is a mature Web application development environment with a focus on ecommerce and dynamic content management.
It offers session and user management, database connectivity (both via SQL and a database abstraction layer), templating, a shopping cart, payment processing, inventory, encryption (via GnuPG, PGP, etc.), tax and shipping calculation, discounts, Web-based administration, localization, event routing, SOAP-based RPC, a custom tag language akin to CFML, and the full power of Perl. It grew out of two earlier projects, MiniVend and Tallyman.
Enhancements:
- A DoS exploit caused by carefully crafted HTTP POST requests has been fixed.
- An apparent Perl bug that allowed code called by DispatchRoutines to overwrite the routines arrays themselves has been worked around.
- Masking of unencrypted credit card numbers to work with a custom MV_CREDIT_CARD_INFO_TEMPLATE that does not match the regexp has been fixed.
- The regexp has been fixed so that it removes the CVV2 value from the unencrypted data.
- A shipping problem with the temporary mv_shipping cart that could cause trouble in cart recalculations has been fixed.
- There are other various bugfixes and minor enhancements.
