ELinks 0.12pre1.GIT now:
------------------------

To be released as 0.12pre2, 0.12rc1, or even 0.12.0.  This branch also
includes the changes listed under "ELinks 0.11.4.GIT now" below.

* bug 954, enhancement 952: Keep track of ECMAScript form and input
  objects instead of constructing new ones on every access.  When the
  corresponding ELinks internal objects are destroyed, detach the
  ECMAScript objects from them, to prevent crashes.  (Bug 954 was
  first added in ELinks 0.11.4, and the bug 620 fix in ELinks 0.12pre1
  made crashes more likely.)
* critical bug 1029 in user SMJS: Prefer JS_CallFunctionValue over
  JS_CallFunction, which can crash if given a closure.
* critical bug 1031: Use the same JSRuntime for both user SMJS and
  scripts on web pages, to work around SpiderMonkey bug 378918.
* bug 1022: Add connection.ssl.trusted_ca_file setting for GnuTLS.
  Before this, ELinks did not trust any certificate authorities when
  it used GnuTLS, so certificate verification always failed if you
  enabled it at connection.ssl.cert_verify.
* bug 1040: Blacklist servers that don't support TLS.  This reduces
  SSL errors especially in HTTP POST requests using GnuTLS.
* minor bug 951: SpiderMonkey scripting objects used to prevent ELinks
  from removing files from the memory cache.

Bugs that should be removed from NEWS before the 0.12.0 release:

* critical: Fix crash after a tab was opened during reload.  This was
  triggered by the bug 620 fix in ELinks 0.12pre1.
* critical bug 1018: Avoid an assertion failure when selecting a value
  from a pop-up menu for an input field in a tab that is no longer
  current, e.g. because another tab was opened with elinks -remote.
  This bug was first released in ELinks 0.12pre1.
* major bug 1026 in user SMJS: Protect the callback of elinks.load_uri
  from the garbage collector.  The elinks.load_uri method was added in
  ELinks 0.12pre1.
* bug 955: Reset buttons no longer run FORM/@onsubmit, and
  ``harmless'' buttons no longer submit the form.  ELinks 0.12pre1
  was the first release that had these bugs.
* bug 1033: Fix memory leak in ECMAScript window.open.  ELinks 0.12pre1
  was the first release that had this bug.
* bug 1034: ``Content-Encoding: deflate'' allows a zlib header as
  specified in RFC 2616.
* Global ECMAScript functions alert, open, and setTimeout again work
  with SEE.  ELinks 0.12pre1 was the first release that supported SEE
  at all.

ELinks 0.12pre1:
----------------

Released on 2008-07-01.  This release also included all the bug fixes
of ELinks 0.11.4, but not the ones made in 0.11.4.GIT.

Notable new features:

* enhancement 822: UTF-8 as terminal charset, not merely UTF-8 I/O
  of a unibyte codepage as in previous versions.  Double-cell (aka
  fullwidth) and supplementary characters work too, but combining
  characters and right-to-left text do not.  The only multibyte
  charset ELinks can decode is still UTF-8, so if the server outputs
  e.g. Shift-JIS, you'd better recode with a proxy.  See more notes
  in features.conf.
* enhancement 844: SMB protocol using libsmbclient.  This replaces
  the smbclient-based code that was disabled in ELinks 0.11.2.

Incompatibilities:

* ECMAScript support is now disabled by default.  It has known
  bugs 548 and 771 with which malicious web pages can hang ELinks,
  and its security goals are undocumented.  If you must enable
  ECMAScript support, it would be prudent to restrict the ELinks
  process with a sandbox of some kind.
* ECMAScript support no longer works with SpiderMonkey versions
  earlier than JS1.5 RC3a.
* Gzip decompression support now requires zlib 1.2.0.2 or later.
* bugs 871, 752: The numbering of terminal.*.colors no longer depends
  on config options.  This change makes elinks.conf portable between
  different configurations but unfortunately not between this and
  previous versions.
* Changed Python goto_url_hook(current) to goto_url_hook(new).  The
  hook can call the new function elinks.current_url() if desired.
  The Python scripting back-end is much more featureful than in
  previous releases, but it is still considered experimental.
* Guile scripting reads hooks.scm rather than internal-hooks.scm.
  (It still reads user-hooks.scm, too.)

Miscellaneous:

* critical bug 723: fix dangling pointer crash when following a link
  in a frame
* critical bug 756: ``assertion (cached)->object.refcount >= 0 failed''
  after HTTP proxy was changed
* critical bug 869: long mailcap entry buffer overflow (non-security)
  when downloading
* tabs opened by -remote now go behind existing dialogs
* major bug 534, enhancement 517: fix HTTP gzip and bzip2
  decompression, and add deflate and LZMA (requires LZMA Utils)
* major bug 503: various fixes in parsing and updating of elinks.conf
* Debian bug 257762: turn terminal transparency off by default
* bug 770: when the user chooses to resume an HTTP download, abort the
  automatically started one and start a new one with the right range
* bug 724: better parsing of escape sequences and control
  sequences from the terminal
* bug 948: fix wrong UTF-8 output after the charset menu was used
* bug 816: convert entity references in input/@value only once

* bug 355: add documents displayed via ``What to do'' dialog to the
  global history
