36 ** The functions in rect.el have been almost completely rewritten...
37 to avoid inserting undesirable spaces, notably at the end of lines.
38 Two typical examples of this old behavior are `string-rectangle', which filled
39 all lines up to the right side of the rectangle, and `clear-rectangle', which
40 filled even empty lines up to the left side.
41
42 This is not the case any more. All these functions have been rewritten to
43 avoid inserting unwanted spaces, and an optional prefix now allows them to
44 behave the old way.
45
46 As a side effect, `move-to-column' now also accepts 'coerce as its second
47 argument, meaning that the line shouldn't be filled if its too short to reach
48 the desired column.
49
50 ** You can now customize and save comments for faces and variables.
51
52 In Custom buffers, a new menu entry allows you to add and edit a comment.
53 Comments for variables can also be assigned by calling
54 `customize-set-(value|variable)' with a prefix argument.
55
56 ** XEmacs now locates the early package hierarchy at ~/.xemacs/packages.

58 This has changed from simply ~/.xemacs.

68 unwanted spaces, and an optional prefix now allows them to behave the
69 old way.
70
71 As a side effect, the FORCE argument to `move-to-column' now
72 understands the special value `coerce', which means that the line
73 should not be filled if it is too short to reach the desired column.
74
75 ** Incremental search will now highlight all visible matches, making
76 it easier to anticipate where consecutive C-s or C-r will place the
77 point. If you want to disable the feature, set
78 `isearch-highlight-all-matches' to nil.
79
80 ** You can now customize and save comments for faces and variables.
81 In Custom buffers, a new menu entry allows you to add and edit a
82 comment. Comments for variables can also be assigned by calling
83 `customize-set-(value|variable)' with a prefix argument.

145 ** New command-line switches -user-init-file and -user-init-directory.
146 These can be used to specify alternate locations for what is normally
147 ~/.emacs and ~/.xemacs.
148
149 Moreover, -user <user> (which used to only work in unpredictable ways)
150 is now equivalent to
151 -user-init-file ~<user>/.emacs -user-init-directory ~<user>/.xemacs.

283 ** user-init-directory is now an absolute, unexpanded path.
284 Previously, `user-init-directory' used to be relative to
285 (concat "~" init-file-user). This turned out to be too complicated
286 for most packages (and some core Lisp files) to use correctly.
287
288 Also, `init-file-user' has been obsoleted in the process.
