| 1 | We are pleased to announce the release of Guile 1.7.2. This is a |
| 2 | 'technology preview' for the upcoming Guile 1.8. It can be found |

| 10 | |
| 11 | This version is guaranteed to contain serious bugs, and the publically |
| 12 | visible interfaces will almost certainly change before 1.8 is |
| 13 | released. The 1.7 releases might be termed "selected snapshots". |
| 14 | |
| 15 | Specifically, libguile has not yet been reviewed for thread-safeness. |
| 16 | |
| 17 | We are releasing it anyway to start testing the new features, and to |
| 18 | get feedback about how well Guile actually behaves in a multi-threaded |
| 19 | setting. |
| 20 | |
| 21 | The shared library major versions have been bumped compared to the 1.6 |
| 22 | series, but they will not be bumped on binary incompatible changes |
| 23 | within the 1.7 series. |

| 26 | The NEWS file is quite long. Here are the most interesting entries: |
| 27 | |
| 28 | Changes since 1.7.1: |
| 29 | |
| 30 | * There is a new way to initalize Guile that allows one to use Guile |
| 31 | from threads that have not been created by Guile. |
| 32 | |
| 33 | * Mutexes and condition variables are now always fair. A recursive |
| 34 | mutex must be requested explicitely. |
| 35 | |
| 36 | * The low-level thread API has been removed. |
| 37 | |
| 38 | * There is a new way to access all kinds of vectors and arrays from |
| 39 | C that is efficient and thread-safe. |
| 40 | |
| 41 | * The concept of dynamic roots has been factored into continuation |
| 42 | barriers and dynamic states. |
