The refresh pass does not correctly keep track of the scope of local variables
and can convert things like \x->(\x->x) x into \x1->(\x2->x2) x2. Fortunately,
it appears that the refresh pass is not needed anymore, so it has been removed.

The function GF.Grammar.PatternMatch.isInConstantForm returned False for all
tables, causing matchPattern to fail, claiming that "variables occur in" the
term if it contains tables.
This problem is several years old, confirmed present in GF 3.2.10 (Oct 2010).

When a browser requests a URL that refers to a directory, web server usually
redirect the browser to the same URL with a trailing '/' added, if one was not
already present. This is to prevent relative links in the returned document
from being interpreted relative to the parent directory instead of the current
document. This type of redirection was missing in gf -server.

Instead of just "syntax error", you now get e.g.
PType is a predefined constant, it can not be redefined
This is a simple change in the parser.

This is in accordance with RFC 4627. http://tools.ietf.org/html/rfc4627
Use application/javascript for JSONP output.

By adding a header
Access-Control-Allow-Origin: *
to the HTTP responses, web browsers are informed that it is OK to call the
services from web pages hosted on other sites.
This is apparently supported in most modern browsers, so it should no longer
be necessary to resort to JSONP.

The package network-2.4.1.1 thoughlessly introduced a backward incompatible
change to the function Network.URI.unEscapeString, see
https://github.com/haskell/network/commit/f2168b1f8978b4ad9c504e545755f0795ac869ce
This also affects the function Network.Shed.Httpd.queryToArguments, which is
used in GFServer.hs.
To remain compatible with older and newer versions of the network package,
we need to stay clear of queryToArguments and unEscapeString. A replacement
function has been added to server/URLEncoding.hs.

that are not in the public API.
Also a couple of haddock documentation fixes.

When compiling a grammar containing characters that are not supported in the
current locale, warning messages could cause GF fail with
hPutChar: invalid argument (Invalid or incomplete multibyte or wide character)
With this quick fix, warning messages that can not be displayed are silently
truncated instead, and compilation continues.

The old partial evaluator has special rules to convert pattern macros in
pre { } expressions. These rules were missing in the new partial evaluator.

This should prevent errors like
Internal error in Compute.ConcreteNew:

Get rid of old-time depend (and ClockTime in favour of UTCTime).

In Data.Operations, the function topoTest2 assumed too much about the form of
the input, compared to the older function topoTest.

The sequence operator (x+y) was implemented by splitting the string to be
matched at all positions and trying to match the parts against the two
subpatterns. To reduce the number of splits, we now estimate the minimum and
maximum length of the string that the subpatterns could match. For common
cases, where one of the subpatterns is a string of known length, like
in (x+"y") or (x + ("a"|"o"|"u"|"e")+"y"), only one split will be tried.

Instead of "Internal error in ...", you now get a proper error message with
a source location and a function name.

Add a conversion rule for ({ l1 = e } ** x).l2 in PMCFG generation. (A rule

files correctly.
The parser works on raw byte sequences read from source files. If parsing
succeeds the raw byte sequences are converted to proper Unicode characters
in a later phase. But the parser calls the function buildAnyTree, which can
fail and generate error messages containing source code fragments, which might
then containing raw byte sequences. To render these error messages correctly,
they need to be converted in accordance with the coding flag in the source
file. This is now done for UTF-8-encoded source files, but should ideally also
be done for other character encodings. (Latin-1-encoded files never suffered
from this problem, since raw bytes are proper Unicode characters in this case.)

It can leave wildcard tables in their origial form, but it easy to handle

It failed to delay table selection when the selector contains a run-time

It's like lookupResDef but it includes a source location in the output.
