+\subsection{Correct the float placement algorithm}
+
+When floats are added to the current or next page, \LaTeX{} makes
+several tests to find an area that can receive the float. One of these
+tests calculates how much space is already used on the page and how
+much additional space is needed to place the float in a particular
+area. This means that it looks not only at the height of the float but also at the
+values from \cs{intextsep} (for \texttt{h} floats) or
+\cs{textfloatsep} and \cs{floatsep} (for \texttt{t} and \texttt{b}
+floats). The resulting space requirement is then stored in an internal
+variable and compared to the space still available on the page.
+
+If the test fails, the algorithm tries the next area. Unfortunately,
+it was reusing the value in that internal variable as the starting point
+for the next test without removing the added space for the float
+separation (\cs{intextsep}, \cs{floatsep}, or \cs{textfloatsep}). Thus
+the comparison was being made with the wrong value (i.e., too high); therefore the test
+may have incorrectly concluded that a float doesn't
+fit, even though in fact it did.
+
+This has now been corrected.
