 <p><b>tlmgr XXXXX (released DDmmm18):</b>
-<li>alternative fallback downloader support: if persistent connections
-  cannot be used (LWP not available), the fallback download program
-  can now be set to either wget or curl using the environment variable
-  TEXLIVE_DOWNLOADER. Esp. for MacOS and https curl is recommended.</li>
-<li>alternative compressor format support: backups and intermediate
-  rollback containers were always created with xz. By setting
-  TEXLIVE_COMPRESSOR to one of xz, lz4, gzip one can select a different
-  format. In particular lz4 and gzip are much faster in producing 
-  the backup containers.</li>
-<li>ssh support: installing from a repository of the form<br>
-    user@machine:/path/to/tlnet
-  should now work. ssh-agent is strongly recommended!</li>
-
+<li>support for curl as a download program, and new default behavior for
+choosing. In this order:
+  <ol>
+  <li>If the environment variable <tt>TEXLIVE_DOWNLOADER</tt> is
+      defined, use it; abort on failure if it doesn't work.
+  <li>If the environment variable <tt>TL_DOWNLOAD_PROGRAM</tt> is
+      defined, use it; abort on failure if it doesn't work.
+  <li>If LWP is available and working, use that (by far the most
+      efficient method, as it supports persistent downloads).
+  <li>If curl is available (from the system) and working, use that.
+  <li>If wget is available (either from the system or TL) and
+      working, use that.
+  </ol>
+  <p>TL still provides <tt>wget</tt> binaries for some platforms, so
+  some download method should always be available.
+  
+<li>support for alternative compressor programs; until now, backups and
+  intermediate rollback containers were always created with xz. Now:
+  <ol>
+  <li>If the environment variable <tt>TEXLIVE_COMPRESSOR</tt> is
+      defined, use it; abort on failure if it doesn't work.
+  <li>If lz4 is available (either from the system or TL) and working, use that.
+  <li>If gzip is available (from the system) and working, use that.
+  <li>If xz is available (either from the system or TL) and working, use that.
+  </ol>
+  <p>lz4 and gzip are much faster in creating tlmgr's local backups.
+  The unconditional use of xz for the tlnet containers is unaffected,
+  to minimize download sizes.
+
+<li><a href="https://openssh.com/">ssh</a> support: installing from a
+  repository of the form <tt>user@machine:/path/to/tlnet</tt> is now
+  supported; the url-like forms
+  <tt>scp://user@machine/path/to/tlnet</tt> and
+  <tt>scp://user@machine/path/to/tlnet</tt> are equivalent. ssh-agent
+  is strongly recommended!
 
 <p><b>tlmgr 47303 (released 14apr18):</b>
 <li>uninstall now a synonym for remove, so requiring --all to remove the
