1) The ability to print and redeem your own gift vouchers.
2) Product prices can now either include or exclude sales tax. If prices exclude sales tax then receipts are printed in a US style and if prices include tax then receipts are printed in a UK style. (See p.71 of the user manual for examples of the receipts look like).
3) An optional fast pay window which can be used if the customer pays in full using a single payment method.
4) An optional item code auto complete window on the sale screen.
5) A new report - tax by date and tax code.
Due to the fact that I work on E4E in my spare time and I have other projects I need to work on, I am currently having to take a break from developing E4E. There will not be another version which includes new features in the near future. I will however continue to respond to support requests, answer questions on the forums and release a new version with any bug fixes if necessary.
