This update now occurs more +regularly while the connection is in use, and the result is used for the tab +icon ("favicon"), allowing multiple open connections and bookmarks of +individual connections to be more easily distinguished from each other. + + * [GUACAMOLE-190](https://issues.apache.org/jira/browse/GUACAMOLE-190) - Use thumbnail of connection for tab icon + +Performance improvements +------------------------ + +Part of the continuing development of the experimental [Guacamole driver for +the X.Org X11 server](https://issues.apache.org/jira/browse/GUACAMOLE-168), the +performance surrounding certain rendering operations has been improved, in +particular the handling of updates to client-side layer size, position, and the +calculation of client lag. + + * [GUACAMOLE-172](https://issues.apache.org/jira/browse/GUACAMOLE-172) - Calculation of processing lag (potentially) incorrect + * [GUACAMOLE-177](https://issues.apache.org/jira/browse/GUACAMOLE-177) - Update layer properties only on flush + * [GUACAMOLE-187](https://issues.apache.org/jira/browse/GUACAMOLE-187) - Improve performance of layer/surface resize + +Printing / file transfer issues +------------------------------- + +Regressions related to [improvements to file transfer made in +0.9.10-incubating](http://guacamole.incubator.apache.org/releases/0.9.10-incubating/#streamlined-file-transfers) +have been identified and fixed. Some of these regressions were specific to +Internet Explorer and Microsoft Edge, but others were generic, such as file +transfer itself possibly blocking interaction until the transfer has completed. + + * [GUACAMOLE-129](https://issues.apache.org/jira/browse/GUACAMOLE-129) - Office mime-types problem with IE + * [GUACAMOLE-138](https://issues.apache.org/jira/browse/GUACAMOLE-138) - Print with Microsoft Edge + * [GUACAMOLE-196](https://issues.apache.org/jira/browse/GUACAMOLE-196) - Backslashes in document title cause printing to fail + * [GUACAMOLE-200](https://issues.apache.org/jira/browse/GUACAMOLE-200) - read() in RDPDR printer can block user input + * [GUACAMOLE-201](https://issues.apache.org/jira/browse/GUACAMOLE-201) - HTTP transfer of files can make connection unresponsive + +Terminal emulation bugs +----------------------- + +The Guacamole terminal emulator is currently intended to implement [the same +subset of VT102 / ECMA-48 codes as the Linux +console](http://man7.org/linux/man-pages/man4/console_codes.4.html). Issues +with Guacamole's implementation of these codes (specifically with handling of +scrolling vs. non-scrolling regions) were identified and fixed. These issues +affected use of GNU screen, tmux, vim, and others. + + * [GUACAMOLE-148](https://issues.apache.org/jira/browse/GUACAMOLE-148) - SSH does not behave properly when using GNU screen + * [GUACAMOLE-149](https://issues.apache.org/jira/browse/GUACAMOLE-149) - Potential busy loop in guac_terminal_display_set_columns() + * [GUACAMOLE-193](https://issues.apache.org/jira/browse/GUACAMOLE-193) - Terminal emulator forgets background color of spaces + +HTTP header authentication +-------------------------- + +Guacamole now supports for authenticating users based on arbitrary HTTP +headers. While this support was always possible to implement via an extension, +such an extension is now included as part of the Guacamole codebase, with a +binary version built alongside the release for convenience. This new extension +allowing the authentication result of external systems sitting between the user +and Guacamole to be trusted. + +**NOTE:** For this to be safe, the header added by the external system **MUST** +be guaranteed to come only from the trusted authentication system itself. It is +up to the configuration of the external system, proxies, etc. to ensure that +users cannot manipulate or add these headers, and thus that the header will be +present if and only if they are authenticated as the user identified by that +header. + + * [GUACAMOLE-195](https://issues.apache.org/jira/browse/GUACAMOLE-195) - Support for HTTP Header-Based Authentication + +Build issues (deprecated functions) +----------------------------------- + +Two functions used within the guacamole-server build, `readdir_r()` and +`avcodec_encode_video2()`, have been marked as deprecated, resulting in build +failures. Guacamole has been modified to no longer depend on these functions, +using the recommended alternatives instead, and the build should no longer fail +on platforms where these functions are deprecated or unavailable. + + * [GUACAMOLE-94](https://issues.apache.org/jira/browse/GUACAMOLE-94) - readdir_r is deprecated + * [GUACAMOLE-167](https://issues.apache.org/jira/browse/GUACAMOLE-167) - avcodec_encode_video2() is deprecated + +Cursor/layer rendering issues +----------------------------- + +In addition to [performance improvements](#performance-improvements), +development for the experimental [Guacamole driver for the X.Org X11 +server](https://issues.apache.org/jira/browse/GUACAMOLE-168) revealed issues +with layer rendering with respect to stacking order, threadsafety, and +transparency. + +In most cases, due to the way that VNC and RDP are currently implemented, these +issues had no effect, but handling of alpha transparency for RDP cursors was +noticeably incorrect when the remote desktop used cursor shadows. This was a +regression due to changes introduced in 0.9.10-incubating for screen sharing, +and should now be fixed. + + * [GUACAMOLE-176](https://issues.apache.org/jira/browse/GUACAMOLE-176) - Support layer position and opacity in guac_common_surface + * [GUACAMOLE-178](https://issues.apache.org/jira/browse/GUACAMOLE-178) - Shared cursor can be obscured by other layers + * [GUACAMOLE-180](https://issues.apache.org/jira/browse/GUACAMOLE-180) - Common display/surface should be threadsafe + * [GUACAMOLE-184](https://issues.apache.org/jira/browse/GUACAMOLE-184) - guac_common_surface_dup() may send invalid PNG + * [GUACAMOLE-185](https://issues.apache.org/jira/browse/GUACAMOLE-185) - Source rectangle for transfer/copy not properly clipped + * [GUACAMOLE-188](https://issues.apache.org/jira/browse/GUACAMOLE-188) - Support alpha transparency in guac_common_surface + * [GUACAMOLE-211](https://issues.apache.org/jira/browse/GUACAMOLE-211) - RDP mouse cursor shadow black + +Client hostname/address tokens +------------------------------ + +Two new [parameter +tokens](http://guacamole.incubator.apache.org/doc/gug/configuring-guacamole.html#parameter-tokens) +have been added, `GUAC_CLIENT_HOSTNAME` and `GUAC_CLIENT_ADDRESS`, representing +the hostname and IP address of the user respectively. The values of these +tokens are determined at the time the user authenticated, and can be used to +include the user's hostname/address within connection parameters. + + * [GUACAMOLE-47](https://issues.apache.org/jira/browse/GUACAMOLE-47) - Get client hostname for use in guac RDP session + +Miscellaneous fixes/improvements +-------------------------------- + +This latest release of Guacamole also adds translation strings for French which +were previously missing, support for RDP servers having Swiss-French keyboard +layouts, and reorganizes some of the internal convenience libraries used by +guacamole-server for the sake of cleanliness and maintainability. + + * [GUACAMOLE-126](https://issues.apache.org/jira/browse/GUACAMOLE-126) - Property "guacd-host" should actually be "guacd-hostname" + * [GUACAMOLE-135](https://issues.apache.org/jira/browse/GUACAMOLE-135) - Add Swiss-French keymap for RDP + * [GUACAMOLE-156](https://issues.apache.org/jira/browse/GUACAMOLE-156) - Missing translations in 0.9.10-incubating + * [GUACAMOLE-169](https://issues.apache.org/jira/browse/GUACAMOLE-169) - Use namespace for common utility headers + * [GUACAMOLE-170](https://issues.apache.org/jira/browse/GUACAMOLE-170) - Always initialize guac_client args + * [GUACAMOLE-171](https://issues.apache.org/jira/browse/GUACAMOLE-171) - Bring broadcast socket into public libguac API + * [GUACAMOLE-175](https://issues.apache.org/jira/browse/GUACAMOLE-175) - Move core of guacd into utility library + * [GUACAMOLE-179](https://issues.apache.org/jira/browse/GUACAMOLE-179) - Move PulseAudio support into utility library + * [GUACAMOLE-186](https://issues.apache.org/jira/browse/GUACAMOLE-186) - Duo-Web-v2.js license missing from LICENSE +
