Dear all, I have just pushed (to master) a patch that modifies the use of date trees in capture templates. If you don't use them, no need to read on.
We used to have 4 different capture targets that work with date trees: file+datetree, file+datetree+prompt, file+weektree, file+weektree+promt. All these are now consolidated to a single new target, file+olp+datetree, which also allows for the optional specification of an outline-path to build the tree under a specific headline instead of at top level in the target file. In this way, you can have several date trees in a file. The type of tree (month or iso-week) is now controlled with a property :tree-type, the option to force a date/time prompt is controlled by the property :time-prompt. For the time being, the old targets will be automatically translated and used correctly. When you use customize to change org-capture-templates, things will automatically be updated next time you change the variable. The recommendation is to go and update your templates, in case at some time in the future, we might remove the compatibility layer. Let me know if any issues arise. Carsten
