I am pleased to announce the 1.1 release of the uWSGI project.

This release focuses on a new option parser subsystem, improved  
perl/psgi  
and ruby/rack support and a new (stable) php plugin. A lot of  
optimizations have been introduced for the fastrouter and the various  
threading modes. This is the first release officially deprecating some  
old-style configuration (see notes).

Changelog [20120317]

- new options parser subsystem

- improved php support

[http://projects.unbit.it/uwsgi/wiki/PHP](http://projects.unbit.it/uwsgi/wiki/PHP)

- multiple spooler with multiprocessing

simply add multiple --spooler options (on different directories) to have  
multiple spooler. Add --spooler-processes to fork() them

- segmentation fault and floating point exceptions manager

you will get a handy backtrace whenever SIGSEGV and SIGFPE are triggered

- never-swap option

enabling this option will force uWSGI to lock all memory areas on  
physical  
memory to avoid on-disk swapping.

- zergpool plugin

another step towards down-free reloads  
[http://projects.unbit.it/uwsgi/wiki/ZergMode](http://projects.unbit.it/uwsgi/wiki/ZergMode)

- perl/psgi multiple interpreters support

you can now mount multiple perl-apps in the same process

- deadlock detector

on some specific conditions, uwsgi locking subsystem can be damaged, the  
master process got a new feature, allowing it to detect such conditions

- pluggable cheaper algos

by default the old-fashioned apache-style spare algorithm is used for  
adaptive process spawning. A new one, based on socket listen queue can  
be  
used, or you can implement a completely new approach:

- new internal routing susbsystem

[http://projects.unbit.it/uwsgi/wiki/InternalRouting](http://projects.unbit.it/uwsgi/wiki/InternalRouting)

- preliminary support for config logic

[http://projects.unbit.it/uwsgi/wiki/ConfigLogic](http://projects.unbit.it/uwsgi/wiki/ConfigLogic)

- log rotation infrastructure

you can now trigger log-rotation simply touching files

- support for paste loggers

- threading improvements

- plugins can now mapped to specific modifiers

- tag is deprecated (use mount option)

- report startup time for apps

- reintroduced expat support

by default libxml2 is searched, if it is not available libexpat will be  
used. If both are not available, xml support will not be compiled in.

- reintroduced remote spooler plugin

- various fastrouter optimizations

- added ruby rvm support

add --gemset option to set a specific rvm gemset

- a lot of fixes all over the place

Notes:

- tag has been deprecated, some simple old-style-config still  
works,  
but you should move to the new mount option. In uWSGI 1.2 the tag  
will map 1:1 to the mount one.

- xml support is now automatically detected (and eventually not compiled  
in)
