 <ul>
+<li><p>Implement a likelihood ratio test as a method for ‘lrtest’ from the lmtest package</p></li>
+<li><p>Add an ‘update’ method for mkinfit objects which remembers fitted parameters if appropriate</p></li>
+<li><p>Add a ‘residuals’ method for mkinfit objects that supports scaling based on the error model</p></li>
+<li><p>Fix a bug in ‘mkinfit’ that prevented summaries of objects fitted with fixed parameters to be generated</p></li>
 <li><p>Add ‘parms’ and ‘confint’ methods for mkinfit objects. Confidence intervals based on the quadratic approximation as in the summary, and based on the profile likelihood</p></li>
 <li><p>Move long-running tests to tests/testthat/slow with a separate test log. They currently take around 7 minutes on my system</p></li>
 <li><p>‘mkinfit’: Clean the code and return functions to calculate the log-likelihood and the sum of squared residuals</p></li>
