===Description===
 +
 +
This version is backward-compatible with all versions 1.0 and later.
 +
 +
See version 1.0.
 +
 +
===Changes===
 +
 +
None
 +
 +
====Bug-fixes====
 +
 +
A bug that affected only the fitting and corrected yield calculations has been fixed.  Occasionally, but not always, this bug resulted in incorrect yield data being passed to Gosia using the "Write Gosia yld file" button, which would affect fitting.  It did not affect integrated yield calculations, simulations or plotting, and the integrated yield function still gave the correct chi-squared value. 
 +
 +
See the recommendations section below.
 +
 +
===Known bugs and issues===
 +
 +
In all versions, it is possible to save an empty session over an existing session.  Frequent backups of the working directory should be made.
 +
 +
This version is not backward-compatible with the beta versions; users must re-define the experimental
 +
definitions.  Level and matrix data CAN be exported from beta versions and imported to this version.  All
 +
later versions are expected to preserve backward compatibility with this version.
 +
Plots of collision functions cannot be generated for all states.
 +
 +
===Recommendations===
 +
 +
Refer to the bug-fix above.  To correct possible errors in prior fits, do the following 'if a fit has been performed'.
 +
No corrections are needed if a fit has not been performed with an earlier version.
 +
 +
# Rewrite the Gosia yield file using the button "Write Gosia yld file."
 +
# Re-run the "Make corrected yields" calculation.
 +
# Re-run the "Fit" calculation.
 +
# Re-run any error calculations that have been done.
 +
# Before comparing experimental yields to calculated yields (plotting, etc.), re-run "Integrated yields" to update the calculated yields for the new matrix elements.
 +
# Save the session.
 +
 +
The new fitted matrix elements can be compared to previous calculations to see if the bug had affected fits.
 +
 +
To migrate from a beta version to this version, export the level scheme and matrix, then import them into a
 +
new session in this version.
