69 tabs are located between the toolbar and the uppermost window, in a | |
70 location called "gutter". If you dislike the buffer tabs, you can | |
71 disable them by specifying: | |

76 `set-default-gutter-position', however currently only MS-Windows | |
77 supports tab widgets with orientations other than vertical.. | |

276 for most packages (and some core Lisp files) to use correctly. | 303 The buffers-tab functionality and progress gauge have been implemented |
277 | 304 using this feature. |
278 Also, `init-file-user' has been obsoleted in the process. | 305 |
306 ** `user-init-file' and `user-init-directory' are now absolute | |
307 file/directory names. Previously, both variables used to be relative | |
308 to (concat "~" init-file-user). This turned out to be too complicated | |
309 for most packages (and some core Lisp files) to use correctly. Also, | |
310 the `init-file-user' variable has been obsoleted in the process. | |

350 `read-variable', `read-command', `read-function', `read-number', | |
351 `read-shell-command', `read-from-minibuffer', and `completing-read' | |
352 now take an additional argument which specifies the default value. If | |
353 this argument is non-nil, it should be a string; that string is used | |
354 in two ways: | |
355 | |
356 It is returned if the user enters empty input. | |
357 It is available through the history command M-n. | |
358 | |
359 ** LDAP changes. | |
360 | |
361 *** The LDAP interface now consists of two layers, a low-level layer | |
362 that closely matches the LDAP C API, and a more convenient | |
363 higher-level set of functions. | |
364 | |
365 *** The low-level functions that used to be named *-internal are now | |
366 named more simply: `ldap-open', `ldap-close', `ldap-search-basic', | |
367 `ldap-add', and `ldap-modify'. They should be used directly for very | |
368 specific purposes (such as multiple operations on a connection) only. | |
369 | |
370 *** The higher-level functions provide a more convenient way to access | |
371 LDAP directories hiding the subtleties of handling the connection, | |
372 translating arguments and ensuring compliance with LDAP | |
373 internationalization rules and formats (currently partly implemented | |
374 only.) This layer provides atomic operations for searches, | |
375 modification, addition and deletion of multiple entries at once: | |
376 `ldap-search-entries', `ldap-add-entries', `ldap-delete-entries', and | |
377 `ldap-modify-entries'. | |
378 | |
379 *** To maintain compatibility with previous code, the now obsolete | |
380 function `ldap-search' is now merely a wrapper that calls either | |
381 `ldap-search-basic' or `ldap-search-entries'. Please don't use the | |
382 `ldap-search' function in your new programs -- a direct call to one of | |
383 the two replacements is more efficient and unambiguous. | |
