Changelog for 1.3.47
We have released LedgerSMB 1.4.12. Users of 1.4 are encouraged to upgrade. This release corrects an issue introduced by an earlier bugfix where users permissions can not be rese from the front-end properly. This affects at least 1.4.10 and 1.4.11.
There are a number of other fixes here too, minor than that one. Please see the complete changelog for details:
LedgerSMB 1.3.41 has been released.
It includes a single fix to the single payment workflow which caused an error in some cases while paying invoices.
This release has a couple of sales tax fixes, a database schema fix and a couple of others. Highly recommend upgrading at earliest opportunity.
Changelog for 1.3.40
If you find yourself in this situation, the answer is to create a 0 (null) payment: Select both the voiding and the voided invoice in the Cash->Payment (or Cash->Receipt) screen. This will clear the invoices against each other with a net-zero result.
LedgerSMB 1.3.33 has been released. This release corrects a number of minor issues, the most major one is that format_amount() was not working on the check printing workflows.
