In the template system, the following %symbols% and [sections] are currently deprecated, because they have been surpassed by {.macros.}.
They are still available for backward compatibilty in 2.x versions, but they are likely not be there since version 3.

%sym-ANY%
  equivalent: {.$sym-ANY.}
  note: you are not forced anymore to start the section name by "sym-"

%up%
  equivalent: {.if| {.%folder% = / .} | {.$up.} .}
  note: you are not forced anymore in keeping the code inside section [up]

%item-added% and %item-modified%
  equivalent: {.time||when=%item-added-dt%.}

%new%
  equivalent: {.if| {.get|is new.} | {.$newfile.} .}
  note: you are not forced anymore in keeping the code inside section [newfile]
