-===Changes from the -STABLE codebase (v2.36.x)=== +
- +
-The main focus of the upcoming release is a revamped import pipeline, capable of scaling to an arbitrary number of processors.  Additional image sizes (full-res, and two more "preview") are now generated by default.  The secondary focus of this release is improving performance through better use of memcache.  Several database bottlenecks (mostly search-related) were identified and sped up considerably.  Finally, the usual smattering of minor features, tweaks, and of course, bugfixes make their usual appearance. +

-===== Current to-do/wish list, in no particular order ===== +
- +
-This list consists of longer-term projects/goals which are generally made up of sub-tasks.  All of these tasks are listed individually in the [[http://bugs.shaftnet.org/|bug tracker]].  Please make new feature requests there. +
- +
-This list also reflects the personal interests of the developers.  There is no set schedule or roadmap for feature implementation, but incentives are certainly appreciated. +
- +
-==Additional themes== +
- +
-We have the original Aqua and a dark derivative (Blackwater) of it, but more, different, themes would be nice.  And while we're dreaming, it would be quite nice to move to a proper templating system (such as Smarty), but that is quite a lot of work for lil' ol me to do. +
- +
-==More UI work== +
- +
-There are lots of little enhancements to the UI I'd like to make, including the use of DHTML to speed up page loads (for the photo page tabs in particular), easy selection between multiple photo versions and image sizes, a scrollable list of images on the photo display page, "what's new" lists, a better system for bulk-tagging images, nicer photo slide frames, etc, etc... +
- +
-==Better RAW Support & Image manipulation pipeline ==  +
- +
-Ideally we could adjust the RAW settings on a per-image basis, and allow regeneration based on the stored settings.  There's actually a lot of work involved here.  [[pobug>6]]  It would also be nice to allow users to add custom image processing pipelines.  (eg sharpen,crop,add a custom border,shadow,user-specified text...). +
- +
-==Improved search== +
- +
-There are many ways we can improve both the speed and functionality of Photo Organizer's searching features, including caching of results, allowing searches of every stored field, and sub-searches.  [[pobug>89]] [[pobug>239]] +
- +
-==Dynamic Albums== +
- +
-Allow users to create 'virtual' albums that are tied to a particular search query.  Any searchable field should be allowed.  An example of how this would work is the current browsing by tags. +
- +
-==GIS/Geospatial Support== +
- +
-Specifically, integrate PO with PostGIS, and use it to add a whole bevy of features -- "locations" can be polygons and location/distance/area-based searching becomes nearly trivial.  Additionally, integrating with additional  Geospatial applications would be much easier. +
- +
-==Content-based searching== +
- +
-Theoretically, Photo Organizer supports bits of this already, but lacks a search backend (and integration instructions) to actually perform "find images like this one" searches.  [[pobug>100]] +
- +
-== Photostreams & RSS == +
- +
-We already have the means to pull up images between arbitrary date ranges, so all that's left is building cool features on top of this -- RSS feeds and pseudo-albums based on date ranges come to mind.  [[pobug>176]]  +
- +
-== External APIs == +
- +
-Implement some sort of RPC mechanism (XMLRPC/SOAP/JSONRPC/whatever) that allows third-party software to call into PO's backend.  There's a lot one can do with this sort of API.  ("Give me ten random highly-rated images from user X's collection"  "give me all the technical info about this photo"  "give me an embedable image+url that I can inline into some CMS system"+
- +
-==New Permission Model== +
- +
-The current permission model is insufficient for many use cases.  [[pobug>8]] [[pobug>245]] Ideally, we'd be able to specify access rights on a per-user basis, not the current "public,clients-only,private" This not particularly important for a single-user system, but makes a huge difference for larger deployments that have well-defined roles.  (See [[New Permission Model]]) +
- +
-==Database Abstraction Improvements== +
- +
-While Photo Organizer will most likely remain PostgreSQL-dependent, we need to migrate to an abstraction layer (eg PHP:PDO) so that we are not tied to using PostgreSQL's bindings.  In the process, we will rewrite all transactions using lazily-bound parameters to completely eliminate any possiblilty of future SQL injection problems.  [[pobug>11]] Additionally, there are other database-level cleanups that need performing.  [[pobug>201]] [[pobug>204]] [[pobug>210]].  This will require PHP 5.1.0 or newer. +
- +
-==Additional Authentication backends and single-sign-on==+
  
-We have the means to authenticate against an external system, and sample LDAP and external database support.  Down the linewe should look into tying into single-sign-on solution like OpenID and/or integration into CMS systems (eg Drupal).+  * [misc] Get rid of "IE7" compatibility library. 
 +  * [themes] Use CSS3 to style radio buttons and checkboxes 
 +  * [themes] Use CSS3 drop-shadows for images. 
 +  * [themes] Use CSS styling for menus instead of the graphics hack. 
 +  * [themes] Convert the action buttons to using spans instead of tables.  
 +  * [misc] Update to tagcloud v3 
 +  * [themes] Use CSS3 to style slide selection 
 +  * [misc] Better memcache logging 
 +  * [misc] Fix some PHP 5.4-related bugs 
 +  * [misc] Added systemd unit file for background workers 
 +  * [fix]  Newer versions of memcached had issues with our code 
 +  * [fix]  Script errors when adding/editing equipment 
 +  * [fix]  Fix a couple of straggling warnings. 
 +  * [misc] Add a script to verify repository checksums 
 +  * [fix]  Bulk update was broken due to earlier theme changes. 
 +  * [fix]  Fix URL on the profile location pages. 
 +  * [misc] Installer now checks for the 'mbstring' extension. 
 +  * [add]  Added support for JPEG-XRWebP, and MJPEG/MJPEG-2000 formats. 
 +  * [add]  Beginnings of JSON-RPC implementation 
 +  * [add]  Remove some of the roadblocks from serving non-JPEG images.

 +  * [fix]  Errors upon emptying the trash weren't displayed properly 
 +  * [fix]  Unescaped search strings could lead to XSS bugs. 
 +  * [add]  Ability to natively print images to any CUPS-accessible printer queue, including ICC correction, custom size/sharpening, and passing arbitrary options. 
 +  * [fix]  Fix detection of PHP's 'mbstring' extension 
 +  * [misc] Eliminate the entire notion of 'duplicates' 
 +  * [misc] Eliminate label printing 
 +  * [misc] Don't display the 'spool' on the main page 
 +  * [fix]  Fix some PHP7-related warnings 
 +  * [fix]  Fix XSS issue on the login page 
 +  * [misc] Eliminate the 'film_iso' relation due to incomplete data.
