  Hi Matthias:
  
  We found that the X Label format $x{%.2f} is no longer accepted after v0.21, changed it to $X fixed this issue.

  Hi chhung,

  I forgot to mention that new feature in the release notes. Actually, I replaced the simple substitution scheme by a full-blown expression parser. The new scheme is described here: http://klayout.de/short_um.html#ruler_properties.

  Frankly I reckoned not many people would use the old scheme and did not spend the effort to provide something backward compatible. To emulate the old "$x{%.2f}" you now can use

  $(sprintf('%.2f',X*1000))
  

  For a brief explanation: the former lower case 'x' is actually X in nm units, hence X*1000, the formatting is done with sprintf rather than the somewhat non-standard {..} notation.

  If it's important I can try to implement a fallback scheme that is backward compatible.

  Best regards,

  Matthias
