| <h1>Release notes</h1> |
| <p>The 1.5.4 release is a bugfix release that addresses miscellaneous bugs from |
| 1.5.3 and earlier, and updates all dependencies to their latest compatible |
| versions. For a full list of all changes in this release, please see the |
| <a href="#changelog">changelog</a> below.</p> |
| |
| <p><strong>The 1.5.4 release is compatible with older 1.x components.</strong> You should |
| upgrade older components to 1.5.4 when possible, however things should continue |
| to work correctly in the interim:</p> |
| |
| <ul> |
| <li>Extensions written for older 1.x releases can be used by 1.5.4.</li> |
| <li>Components written for the version of the Guacamole protocol used by older |
| 1.x releases can be used with components of the 1.5.4 release.</li> |
| </ul> |
| |
| <p>Regardless of inter-component compatibility, <strong>there are changes in 1.5.4 which |
| may affect downstream users of Guacamole’s APIs</strong>. Please see the <a href="#deprecation--compatibility-notes">deprecation |
| / compatibility notes</a> section for more |
| information.</p> |

| <h1 id="deprecation--compatibility-notes">Deprecation / Compatibility notes</h1> |
| |
| <p>Each 1.x release of Apache Guacamole should be compatible with components of |
| older 1.x releases. This compatibility is intended at the Guacamole protocol |
| level and at the extension level, but not necessarily at the API level. This |
| means:</p> |
| |
| <ul> |
| <li>Extensions from older 1.x releases should still work in binary form, but may |
| need code changes before their source will build against a newer version of |
| guacamole-ext.</li> |
| <li>Software which uses the Guacamole protocol of an older 1.x release should |
| still work.</li> |
| <li>Software which uses libguac from an older 1.x release should still work by |
| continuing to use the libguac from that release, as newer versions of |
| libguac may not be API/ABI compatible. In the case of third-party protocol |
| support plugins for guacd, this means that the guacd from that release must |
| also be used. Compatibility with respect to libguac is represented by the |
| <a href="https://en.wikipedia.org/wiki/Soname">soname</a>.</li> |
| <li>You should update to newer versions where applicable and when possible.</li> |
| </ul> |
| |
| <p>As of 1.5.4, the following changes have been made which affect compatibility |
| with past releases:</p> |
| |
| <h2 id="bulk-user-join-support-join_pending_handler">Bulk user join support (<code class="language-plaintext highlighter-rouge">join_pending_handler</code>)</h2> |
| |
| <p>When a user joins an established connection via Guacamole’s sharing |
| functionality, that user’s display state must be synchronised with the existing |
| display state of the connection such that future updates will have the expected |
| effects. Historically, this synchronization was done individually for each |
| joining user via a single handler called <code class="language-plaintext highlighter-rouge">join_handler</code>.</p> |
| |
| <p>As of 1.5.4, <code class="language-plaintext highlighter-rouge">join_pending_handler</code> has been added to allow <em>all</em> joining users |
| to be synchronized at the same time. If using this new bulk synchronization |
| support, the <code class="language-plaintext highlighter-rouge">join_handler</code> will be used primarily to parse user-specific |
| connection parameters, while the <code class="language-plaintext highlighter-rouge">join_pending_handler</code> will be used to |
| synchronize the display state to all users that are about to join. Using |
| <code class="language-plaintext highlighter-rouge">join_pending_handler</code> avoids having to re-encode the same display state |
| multiple times.</p> |
| |
| <ul> |
| <li class="bug">Race condition can cause the first user for a connection to miss updates (<a href="https://issues.apache.org/jira/browse/GUACAMOLE-1846">GUACAMOLE-1846</a>)</li> |
| </ul> |
| |
| <h2 id="memory-management-macros">Memory management macros</h2> |
| |
| <p>The latest version of libguac provides <a href="/doc/1.5.4/libguac/mem_8h.html">a series of <code class="language-plaintext highlighter-rouge">guac_mem_*()</code> macros</a> |
| for memory management and memory-related calculations that perform checked |
| arithmetic. These macros are intended to replace manual usage of <code class="language-plaintext highlighter-rouge">malloc()</code>, |
| <code class="language-plaintext highlighter-rouge">calloc()</code>, <code class="language-plaintext highlighter-rouge">realloc()</code>, and <code class="language-plaintext highlighter-rouge">free()</code> and should be preferred.</p> |
| |
| <p>The addition of these macros does not itself affect compatibility, however |
| established libguac functions that previously required returned memory to be |
| freed using <code class="language-plaintext highlighter-rouge">free()</code> now document that returned memory should be freed with |
| <code class="language-plaintext highlighter-rouge">guac_mem_free()</code>. Existing usage of <code class="language-plaintext highlighter-rouge">free()</code> instead of <code class="language-plaintext highlighter-rouge">guac_mem_free()</code> will |
| continue to work but should be migrated when possible.</p> |
| |
| <ul> |
| <li>Add libguac convenience functions for memory management (<a href="https://issues.apache.org/jira/browse/GUACAMOLE-1867">GUACAMOLE-1867</a>)</li> |
