IP_Clearance Impact

lp_solve

lp_solve is being replaced by CoinMP

CoinMP comes from the Coin-OR open source project, an open source project that involves operations research professionals and includes cutting edge algorithms.

This functionality is invoked by the user in Calc via Tools->Solver.  It is used for solving linear programming problems, including integer programming.

According to one research paper CoinMP offers superior performance compared to lp_solve.  So the overall user impact from this change should be positive.

xpdf

PDF import can only be built when the poppler library is pre-installed on the system.

MySQL Connector/C++

MySQL connector can only be built when the C++ connector is pre-installed on the system.

glibc

glibc is being removed from the product

No impact for user. Developers can not use getopt() function to parse command line.

SVG: librsvg, libcroco, libgsf, gdk-pixbuf, glib, gettext, pango

SVG using an external renderer is disabled, thus this new feature for 3.4 is there but creates no visualizations of embedded SVGs. Work for a replacement is ongoing.

libwpd

The libwpd library is being removed from the product.

The WordPerfect filter ("WordPerfect Document (.wpd)") won't be available anymore. No *replacement until somebody will work on a filter extension that can be installed separately

fonts (liberation and gentium)

These fonts are being removed from the distribution due to an incompatible license.

Users may install these fonts to their system, in accordance with their license.  If they do this, then there is no further user impact.

libneon

The neon library is being removed from the distribution due to an incompatible license.

The neon library is used to for all http based communication including WebDAV. Without a replacement it is for example not possible to insert an image via an http Url. Work on a replacement (118569) has started but we will potentially loose WebDAV support at the beginning.
