Jul 2019 - version 1.17.0
This is a minor update to address a few issues:
May 2019 - version 1.15.0 and 1.16.0
These releases were mainly to do with changes to back-end administration tools used by Sealed Envelope.
In addition a few issues were fixed:
We now produce a validation certificate for each release. This confirms the software was produced according to our SOPs and has passed all of our internal testing procedures.
March 2019 - version 1.14.1
Some minor updates to fix an error that could occur when parsing the strata on the create a randomisation list form, and a more general change to the way errors are handled.
March 2019 - version 1.14.0
You can now pay online for randomisations, making it quicker and easier for you to set-up or extend your randomisation system!
We’ve changed the name of what we used to call the Simple with list service to Simple +. This better reflects the fact that Simple + has additional features (eligibility criteria and randomisation by SMS) and doesn’t necessarily use a list.
A secure online checkout that allows set-up costs and randomisation blocks to be paid for instantly has been added. Ordering is also possible with payment by invoice through the same checkout, but in this case orders are not fulfilled until the invoice has been paid.
Administrative features (online payment, sending randomisations by email, SMS instructions and deleting the trial) have been moved into a dedicated administration area. This is password protected with the trial password.
Applies to Simple + only with a randomisation list.
Warnings are now shown when the number of allocations for any stratum in a randomisation list may be too short to reach the sample size or randomisation limit.
In the example screenshot the trial uses a list stratified by age group, and the Under 4 age group has 19 unused allocations in the randomisation list. Since there are 46 randomisations remaining until the limit of 50 is reached, the list may be too short. The list will run out if more than 19 randomisations are carried out for the Under 4 age group.
