#summary Changelog of distributed PPSS
#labels Featured
=== 2.31 ===
- The status screen in distributed mode is now working properly again.
=== 2.30 ===
- PPSS now operates fully asynchronous. There are no polling mechanisms, every action is almost realtime.
=== 2.21 ===
- Fixed bug in new mechanism for detecting multiple PPSS instances. (My fault).
- By default now PPSS creates a directory 'ppss' in the current working dir of PPSS.
By using 'export PPSS_DIR=/some/dir' you can change the directory used.
=== 2.20 ===
- PPSS did not take into account that different users can run PPSS on a single system. This has been fixed. Thanks to Cinly Ooi
- If a user is starting another instance of PPSS, the second instance will abort unless the -F option is specified.
Please note that if you run multiple instances of PPSS under the same user account, all instances will process items but fail to terminate.
- Improved error reporting.
=== 2.19 ===
- Improved filename sanitization.
- Fixed typo.
=== 2.18 ===
- PPSS now also record CPU model of Mac OS X devices.

=== 2.16 ===
- Cleaned up output to screen.

- Also, the ; character is now supported in filenames.
=== 2.14 ===
Major rework on path and filename handling. Filenames are now properly sanitized for special characters such as ',& and ( ).
Also, PPSS recreates the directory structure of the source location of files, based on the -f option.
=== 2.10 ===
Fixed important bugs when using an input file instead of an input directory.
=== 2.09 ===
Fixed important bug: when deploying a key must be used to logon to the nodes using scp.
=== 2.08 ===
Fixed some bugs...
=== 2.07 ===
* User can now specify the known_hosts file with option -K. The fact that a known_hosts file must exist when distributing PPSS to nodes was not documented.
=== 2.06 ===
* Forgot to update the version number within the script.
=== 2.05 ===
* Deployment of PPSS to nodes is now performed in parallel, by executing the deploy function with &."
* It is now possible to specify the output directory and/or output filename within the -c option.
=== 2.04 and older ===
I didn't realise that a changelog might be relevant until 2.05.
