+ltugboat.cls:
+- new abbrevations: \RIT, \tbUTF.
+
+\tbUTF expands to \acro{UTF}, and, if the next character is a -
+(e.g., \tbUTF-8), don't allow breaking at it. (We don't define \UTF
+since other packages already do.)
+tugboat.bst:
+- new entry type @ctan, following ctanbib (https://ctan.org/pkg/ctanbib).
+- use \emph{...} instead of {\em ...}, so we get italic corrections.
+
+----
+2.24 (2020-11-14):
ltugboat.cls:
- new hyphenation exceptions: Ja-pa-nese, Pak-i-stan.
- new abbrevations: \macOS, \OpTeX.

+%%% New field bookauthor for @incollection and @inproceedings.
%%% Abbreviate "page(s)" to "p(p).",
%%% "volume" to "vol.",
%%% "editor(s)" to "ed(s)".
%%% Output "Ph.D." rather than "PhD".
%%% Output "No." and "no." for number field.

%%% Set urlintro="".
%%% Always use https://doi.org/ for the doi url, and omit doi: prefix
-%%% (incomplete: doi urls not linked correctly).
-%%% Omit spaces between author initials, like "A.B. Smith".
+%%% (todo: doi urls not linked correctly).
%%% Truncate long author lists in format.names (max.names, trunc.num)
%%% and omit "and" from author lists, per Oren P.
-%%% New field bookauthor for @incollection and @inproceedings.
+%%% Use \emph instead of \em so we get automatic italic corrections.
%%% New fields for editors:
+%%% "journaltie" - ~ instead of space after journal name.
%%% "newpage" - force page break after entry;
+%%% "prebibitem" - material output before \bibitem, with newline appended.
%%% "urlnewline" - force line break before url value;
