API

• Document objects now track whether any document positions have been modified so that replacing a modified document can completely skip considering updating positions if none have changed. Currently the flint, chert, and brass backends implement this optimisation. A common case this speeds up is adding and/or removing boolean filter terms to/from existing documents - for example this gives an 18% speedup for adding tags in notmuch.

Documentation

• Assorted improvements to both the API documentation and elsewhere.

Bindings

• Add missing wrappers for Database::has_positions() and TermIterator::positionlist_count(), and correct the return type of Database::get_doclength() from double to Xapian::termcount.

CSharp

• Fix iterator ++ and -- so that the reference to the object isn't released prematurely, which was causing an occasional crash if the garbage collection happened at just the wrong moment,

Java (SWIG-based)

• Put the SWIG-generated Java bindings in package org.xapian.

• Add documentation and examples.

Lua

• Merge latest Lua changes from Xiaona Han.

Perl (SWIG-based)

• perl/t/symbol-test.t: Fix to work when built against an installed xapian-core. (ticket#558)

PHP

• Change PHP examples and test program to use 'include "xapian.php"' like user code should (rather than 'include "php5/xapian.php"' as they did previously).
