| cad4775f | 1 | We are pleased to announce the release of Guile 1.7.1. This is a |

| 11 | This version is guaranteed to contain serious bugs, and the publically | |
| 7023d642 MV |
12 | visible interfaces will almost certainly change before 1.8 is |
| 13 | released. The 1.7 releases might be termed "selected snapshots". | |

| 15 | We are releasing it anyway to start testing the new features, and to | |
| 16 | get feedback about how difficult or tedious it is to switch from Guile | |
| 17 | 1.6 to this series. | |
| 18 | ||
| 19 | Ideally, you should be able to just link your program with Guile 1.7.1 | |
| 20 | instead of with Guile 1.6.x. You will get many warnings about | |
| 21 | deprecated features, but your program should nevertheless run | |
| 22 | correctly. If you find that this is not the case (which is quite | |
| 23 | likely) please do not change your program yet. Instead, report the | |
| 24 | problem to <bug-guile@gnu.org>. | |
| 25 | ||
| 26 | The shared library major versions have been bumped compared to the 1.6 | |
| 27 | series, but they will not be bumped on binary incompatible changes | |
| 28 | within the 1.7 series. | |

| 31 | The NEWS file is quite long. Here are the most spectacular entries in | |
| 32 | a condensed form: | |
| 33 | ||
| 34 | Changes since the 1.6.x series: | |
| 35 | ||
| 36 | - Guile is now licensed with the GNU Lesser General Public License. | |
| 37 | ||
| 38 | - The manual is now licensed with the GNU Free Documentation License. | |
| 39 | ||
| 40 | - We now use GNU MP for bignums. | |
| 41 | ||
| 42 | - We now use native POSIX threads for real concurrent threads. | |
| 43 | ||
| 44 | - There is now support for copy-on-write substrings and | |
| 45 | mutation-sharing substrings. | |
| 46 | ||
| 47 | - We now have exact rationals, such as 1/3. | |
| 48 | ||
| 49 | - A new family of functions for converting between C values and | |
| 50 | Scheme values has been added that is future-proof and thread-safe. | |
| 51 | ||
| 52 | - The INUM macros like SCM_MAKINUM have been deprecated. | |
| 53 | ||
| 54 | - The macros SCM_STRINGP, SCM_STRING_CHARS, SCM_STRING_LENGTH, | |
| 55 | SCM_SYMBOL_CHARS, and SCM_SYMBOL_LENGTH have been deprecated. | |
| 56 | ||
| 57 | - There is a new way to deal with non-local exits and re-entries in | |
| 58 | C code, which is nicer than scm_internal_dynamic_wind. | |
| 59 | ||
| 60 | - There are new malloc-like functions that work better than | |
| 61 | scm_must_malloc, etc. | |
| 62 | ||
| 63 | and most importantly | |
| 64 | ||
| 65 | - call-with-current-continuation is now also available under the name | |
| 66 | call/cc. | |
| 67 | ||
| 68 | See NEWS and the manual for more details. |
