    22# update GSASIIctrlGUI.updateNoticeDict). Lines starting with "#" are
    33# comments.
    4 # Each version is tagged with a version number and a colon. All subsequent text
    5 # is the notice for that version with one or more blank lines between.
    6 
    7 # 5000: This is text for version 5000. It spans several lines.
    8 #   Note that indents are ignored, but 2 percent signs create a newline. %%%%This
    9 #  starts on a new line with a blank after the previous.
    10 
    11 # 1234: This is text for version 1234. The second colon here (:) is ignored.
     4# Each version should be tagged with a version number and a colon. All subsequent text
     5# will be part of the the notice for that version. Separate versions
     6# with one or more blank lines between. Note that line breaks and
     7# indentation are ignored. Use && to insert a single "&"
     8# character. Use %% to insert a new line.

    13104919: With this version of GSAS-II, the profile functions have been changed to account for possible variation in the powder
    14 pattern step size across the scan. This will likely change the histogram scale factor (see Sample Parameters), peak
    15 intensities (see Peak List) and background peak intensities (see Background). For Constant Wavelength data, they will change
    16 by a factor related to the pattern step size, e.g. for 11BM data with a step size of 0.001 deg 2-theta the new scale factor will be
    17 ~0.1 times the old one. If you choose to repeat the refinement for this project, you may need to be sure that parameters affecting
    18 peak shape are turned off for the initial refinement. It should converge quickly to the new scale factor.
    19 %%For TOF data there may be similar changes to the scale factor && peak intensities as noted above. Significant improvement in profile
    20 residuals have been observed in some cases with these new functions.
    21 This change is of no consequence for single crystal, small angle or reflectometry data in GSAS-II.
     11  pattern step size across the scan. This will likely change the histogram scale factor (see Sample Parameters), peak
