### Deprecated
- Stamen Design has discontinued to server map tiles since 2023-07-31.
    Therefore, all `supply/source` options based on Stamen Design are
    deprecated now, namely
    - `stamen terrain`
    - `stamen terrain-background`
    - `stamen terrain-labels`
    - `stamen terrain-lines`
    - `stamen toner`
    - `stamen toner-lite`
    - `stamen toner-hybrid`
    - `stamen toner-background`
    - `stamen toner-labels`
    - `stamen toner-lines`
    - `stamen watercolor`
    All these options are now not documented any more, but for some time
    are still available for old documents with cached map tiles.

### Removed
- Requirement for packages `expl3`, `xparse`, and `pdftexcmds`

### Fixed
- Links to the WMS maps of Bundesamt für Kartographie und Geodäsie changed
- Overwrite warning while generating `maptiles.texpy`
- Orthodrome drawing with identical starting and final point is now silently ignored



## [1.02] - 2020-08-06

### Added
- New options
  `/mermap/supply/area from marker input` and
  `/mermap/supply/add area from marker input`
  which allow to fit a map to a given external list of marker positions.
- New option `/mermap/fail on missing resource` to control
  compilation behavior for missing resource files.
- New marker option `/mermap/marker/distance` with corresponding
  macro `\mrcmarkerdistance` (issue #2)

### Deprecated
- Openrouteservice has discontinued mapsurfer tiles since June 2020.
  Therefore, `/mermap/supply/source=openrouteservice mapsurfer`
  is deprecated now. It is not documented any more, but
  for some time it is still available for old documents with
  cached map tiles.

    - `/mermap/marker/link`
    - `/mermap/marker/use urls`
    - `/mermap/marker/ignore urls`
    - `/mermap/marker/use links`
    - `/mermap/marker/ignore links`
