Get notified when packages are built

A new feature has been added. FreshPorts already tracks package built by the FreeBSD project. This information is displayed on each port page. You can now get an email when FreshPorts notices a new package is available for something on one of your watch lists. However, you must opt into that. Click on Report Subscriptions on the right, and New Package Notification box, and click on Update.

FInally, under Watch Lists, click on ABI Package Subscriptions to select your ABI (e.g. FreeBSD:14:amd64) & package set (latest/quarterly) combinatio for a given watch list. This is what FreshPorts will look for.

Description:
KKTDirect implements an ordering method and accompanying factorization for the direct solution of saddle-point matrices (also known as KKT or equilibrium matrices). A simple constraint on ordering together with an assumption on the rank of parts of the matrix are sufficient to guarantee the existence of the LDL^T factorization, stability concerns aside. In fact, D may be taken to be a diagonal matrix with +/-1 along the diagonal, and be fully determined prior to factorization, giving rise to a "signed Cholesky" factorization. A modified minimum-degree-like algorithm which incorporates this constraint is used, along with a simple algorithm to modify an existing fill-reducing ordering to respect the constraint. While a stability analysis is lacking, numerical experiments indicate that this is generally sufficient to avoid the need for numerical pivoting during factorization, with clear possible benefits for performance. Note this is only alpha-quality proof-of-concept code: for example, out-of-memory errors are not handled gracefully, and the provided Minimum Degree routine is not yet competitive with other packages.

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.
