132 parser. The old parser can still be used by setting the new directive
133 SSILegacyExprParser. [Stefan Fritsch]
135 *) core: Add some features to ap_expr for use by mod_include: a restricted
136 mode that does not allow to bypass request access restrictions; new
137 variables DOCUMENT_URI (alias for REQUEST_URI), LAST_MODIFIED; -A as an
138 alias for -U; an additional data entry in ap_expr_eval_ctx_t for use by
139 the consumer; an extensible ap_expr_exec_ctx() API that allows to use that
140 data entry. [Stefan Fritsch]
142 *) mod_include: Merge directory configs instead of one SSI* config directive
143 causing all other per-directory SSI* config directives to be reset.
146 *) mod_charset_lite: Remove DebugLevel option in favour of per-module
147 loglevel. [Stefan Fritsch]
149 *) core: Add ap_regexec_len() function that works with non-null-terminated
150 strings. PR 51231. [Yehezkel Horowitz <horowity checkpoint com>]

156 for SCGI/FCGI. PR 50880, 50851. [Mark Montague <mark catseye.org>,
159 *) mod_cache: When content is served stale, and there is no means to
160 revalidate the content using ETag or Last-Modified, and we have
161 mandated no stale-on-error behaviour, stand down and don't cache.
162 Saves a cache write that will never be read.

192 processes. Add end_generation hook for notification when the last
193 MPM child of a generation exits. [Jeff Trawick]
195 *) mod_ldap: Make LDAPSharedCacheSize 0 create a non-shared-memory cache per
196 process as opposed to disabling caching completely. This allows to use
197 the non-shared-memory cache as a workaround for the shared memory cache
198 not being available during graceful restarts. PR 48958. [Stefan Fritsch]
200 *) Add new ap_reserve_module_slots/ap_reserve_module_slots_directive API,
201 necessary if a module (like mod_perl) registers additional modules late
202 in the startup phase. [Stefan Fritsch]
204 *) core: Prevent segfault if DYNAMIC_MODULE_LIMIT is reached. PR 51072.

230 *) mod_info: Dump config to stdout during startup if -DDUMP_CONFIG is
231 specified. PR 31956. [Stefan Fritsch]

253 of bound backend LDAP connections. PR47634 [Eric Covener]
255 *) mod_cache: Make CacheEnable and CacheDisable configurable per
256 directory in addition to per server, making them work from within
257 a LocationMatch. [Graham Leggett]
259 *) worker, event, prefork: Correct several issues when built as
260 DSOs; most notably, the scoreboard was reinitialized during graceful
261 restart, such that processes of the previous generation were not
262 observable. [Jeff Trawick]
264 Changes with Apache 2.3.11
266 *) mod_win32: Added shebang check for '! so that .vbs scripts work as CGI.
267 Win32's cscript interpreter can only use a single quote as comment char.
270 *) mod_proxy: balancer-manager now uses POST instead of GET.
273 *) core: new util function: ap_parse_form_data(). Previously,
274 this capability was tucked away in mod_request. [Jim Jagielski]
276 *) core: new hook: ap_run_pre_read_request. [Jim Jagielski]
278 *) mod_cache: When a request other than GET or HEAD arrives, we must
279 invalidate existing cache entities as per RFC2616 13.10. PR 15868.
282 *) modules: Fix many modules that were not correctly initializing if they
283 were not active during server startup but got enabled later during a
284 graceful restart. [Stefan Fritsch]
286 *) core: Create new ap_state_query function that allows modules to determine
287 if the current configuration run is the initial one at server startup,
288 and if the server is started for testing/config dumping only.
291 *) mod_proxy: Runtime configuration of many parameters for existing
292 balancers via the balancer-manager. [Jim Jagielski]
294 *) mod_proxy: Runtime addition of new workers (BalancerMember) for existing
295 balancers via the balancer-manager. [Jim Jagielski]
297 *) mod_cache: When a bad Expires date is present, we need to behave as if
298 the Expires is in the past, not as if the Expires is missing. PR 16521.
299 [Co-Advisor <coad@measurement-factory.com>]
301 *) mod_cache: We must ignore quoted-string values that appear in a
302 Cache-Control header. PR 50199. [Graham Leggett]
304 *) mod_dav: Revert change to send 501 error if unknown Content-* header is
305 received for a PUT request. PR 42978. [Stefan Fritsch]

308 take precedence if present. PR 35247. [Graham Leggett]
310 *) mod_ssl: Fix a possible startup failure if multiple SSL vhosts
311 are configured with the same ServerName and private key file.
312 [Masahiro Matsuya <mmatsuya redhat.com>, Joe Orton]

321 PR 50434 [Stefan Fritsch]
323 *) core: Add support to set variables with the 'Define' directive. The
324 variables that can then be used in the config using the ${VAR} syntax
325 known from envvar interpolation. [Stefan Fritsch]

328 ProxyAddHeaders defaults to On. [Vincent Deffontaines]
330 *) mod_slotmem_shm: Increase memory alignment for slotmem data.

334 SSLOCSPResponseMaxAge, SSLOCSPResponseTimeSkew.
335 [Kaspar Brand <httpd-dev.2011 velox.ch>]
337 *) mod_ssl: Revamp output buffering to reduce network overhead for
338 output fragmented into many buckets, such as chunked HTTP responses.
341 *) core: Apply <If> sections to all requests, not only to file base requests.
342 Allow to use <If> inside <Directory>, <Location>, and <Files> sections.
343 The merging of <If> sections now happens after the merging of <Location>
344 sections, even if an <If> section is embedded inside a <Directory> or
345 <Files> section. [Stefan Fritsch]
347 *) mod_proxy: Refactor usage of shared data by dropping the scoreboard
348 and using slotmem. Create foundation for dynamic growth/changes of
349 members within a balancer. Remove BalancerNonce in favor of a
350 per-balancer 'nonce' parameter. [Jim Jagielski]
352 *) mod_status: Don't show slots which are disabled by MaxClients as open.
353 PR: 47022 [Jordi Prats <jordi prats gmail com>, Stefan Fritsch]
355 *) mpm_prefork: Fix ap_mpm_query results for AP_MPMQ_MAX_DAEMONS and
358 *) mod_authz_core: Fix bug in merging logic if user-based and non-user-based
359 authorization directives were mixed. [Stefan Fritsch]
361 *) mod_authn_socache: change directive name from AuthnCacheProvider
362 to AuthnCacheProvideFor. The term "provider" is overloaded in
363 this module, and we should avoid confusion between the provider
364 of a backend (AuthnCacheSOCache) and the authn provider(s) for
365 which this module provides cacheing (AuthnCacheProvideFor).
368 *) mod_proxy_http: Allocate the fake backend request from a child pool
369 of the backend connection, instead of misusing the pool of the frontend
370 request. Fixes a thread safety issue where buckets set aside in the
371 backend connection leak into other threads, and then disappear when
372 the frontend request is cleaned up, in turn causing corrupted buckets
373 to make other threads spin. [Graham Leggett]
375 *) mod_ssl: Change the format of the SSL_{CLIENT,SERVER}_{I,S}_DN variables
376 to be RFC 2253 compatible, convert non-ASCII characters to UTF8, and
377 escape other special characters with backslashes. The old format can
378 still be used with the LegacyDNStringFormat argument to SSLOptions.
380 *) core, mod_rewrite: Make the REQUEST_SCHEME variable available to
381 scripts and mod_rewrite. [Stefan Fritsch]
383 *) mod_rewrite: Allow to use arbitrary boolean expressions (ap_expr) in
384 RewriteCond. [Stefan Fritsch]
386 *) mod_rewrite: Allow to unset environment variables using E=!VAR.
387 PR 49512. [Mark Drayton <mark markdrayton info>, Stefan Fritsch]
389 *) mod_headers: Restore the 2.3.8 and earlier default for the first
390 argument of the Header directive ("onsuccess"). [Eric Covener]
392 *) core: Disallow the mixing of relative and absolute Options PR 33708.
393 [Sönke Tesch <st kino-fahrplan.de>]
395 *) core: When exporting request headers to HTTP_* environment variables,
396 drop variables whose names contain invalid characters. Describe in the
397 docs how to restore the old behaviour. [Malte S. Stretz <mss apache org>]
399 *) core: When selecting an IP-based virtual host, favor an exact match for
400 the port over a wildcard (or omitted) port instead of favoring the one
401 that came first in the configuration file. [Eric Covener]
403 *) core: Overlapping virtual host address/port combinations now implicitly
404 enable name-based virtual hosting for that address. The NameVirtualHost
405 directive has no effect, and _default_ is interpreted the same as "*".
408 *) core: In the absence of any Options directives, the default is now
409 "FollowSymlinks" instead of "All". [Igor Galić]
411 *) rotatelogs: Add -e option to write logs through to stdout for optional
412 further processing. [Graham Leggett]
414 *) mod_ssl: Correctly read full lines in input filter when the line is
415 incomplete during first read. PR 50481. [Ruediger Pluem]
417 *) mod_authz_core: Add AuthzSendForbiddenOnFailure directive to allow
418 sending '403 FORBIDDEN' instead of '401 UNAUTHORIZED' if authorization
419 fails for an authenticated user. PR 40721. [Stefan Fritsch]
421 Changes with Apache 2.3.10
423 *) mod_rewrite: Don't implicitly URL-escape the original query string
424 when no substitution has changed it. PR 50447. [Eric Covener]
426 *) core: Honor 'AcceptPathInfo OFF' during internal redirects,
427 such as per-directory mod_rewrite substitutions. PR 50349.
430 *) mod_rewrite: Add 'RewriteOptions InheritBefore' to put the base
431 rules/conditions before the overridden rules/conditions. PR 39313.
432 [Jérôme Grandjanny <jerome.grandjanny cea.fr>]
434 *) mod_autoindex: add IndexIgnoreReset to reset the list of IndexIgnored
435 filenames in higher precedence configuration sections. PR 24243.
438 *) mod_cgid: RLimit* directive support for mod_cgid. PR 42135
441 *) core: Fail startup when the argument to ServerName looks like a glob
442 or a regular expression instead of a hostname (*?[]). PR 39863
443 [Rahul Nair <rahul.g.nair gmail.com>]
445 *) mod_userdir: Add merging of enable, disable, and filename arguments
446 to UserDir directive, leaving enable/disable of userlists unmerged.
447 PR 44076 [Eric Covener]
449 *) httpd: When no -k option is provided on the httpd command line, the server
450 was starting without checking for an existing pidfile. PR 50350

454 backend fails. PR 50332.
455 [Daniel Ruggeri <DRuggeri primary.net>, Ruediger Pluem]
457 *) mod_cache_disk: Fix Windows build which was broken after renaming
458 the module. [Gregg L. Smith]
460 Changes with Apache 2.3.9
462 *) SECURITY: CVE-2010-1623 (cve.mitre.org)
463 Fix a denial of service attack against mod_reqtimeout.
466 *) mod_headers: Change default first argument of Header directive
467 from "onsuccess" to "always". [Eric Covener]
469 *) mod_include: Add the onerror attribute to the include element,
470 allowing an URL to be specified to include on error. [Graham
473 *) mod_cache_disk: mod_disk_cache renamed to mod_cache_disk, to be
474 consistent with the naming of other modules. [Graham Leggett]
476 *) mod_setenvif: Add SetEnvIfExpr directive to set env var depending on
477 expression. [Stefan Fritsch]
479 *) mod_proxy: Fix ProxyPassInterpolateEnv directive. PR 50292.
482 *) suEXEC: Add Suexec directive to disable suEXEC without renaming the
483 binary (Suexec Off), or force startup failure if suEXEC is required
484 but not supported (Suexec On). Change SuexecUserGroup to fail
485 startup instead of just printing a warning if suEXEC is disabled.
488 *) core: Add Error directive for aborting startup or htaccess processing
489 with a specified error message. [Jeff Trawick]
491 *) mod_rewrite: Fix the RewriteEngine directive to work within a
492 location. Previously, once RewriteEngine was switched on globally,
493 it was impossible to switch off. [Graham Leggett]
495 *) core, mod_include, mod_ssl: Move the expression parser derived from
496 mod_include back into mod_include. Replace ap_expr with a parser
497 derived from mod_ssl's parser. Make mod_ssl use the new parser. Rework
498 ap_expr's public interface and provide hooks for modules to add variables
499 and functions. [Stefan Fritsch]
501 *) core: Do the hook sorting earlier so that the hooks are properly sorted
502 for the pre_config hook and during parsing the config. [Stefan Fritsch]
504 *) core: In the absence of any AllowOverride directives, the default is now
505 "None" instead of "All". PR49823 [Eric Covener]
507 *) mod_proxy: Don't allow ProxyPass or ProxyPassReverse in
508 <Directory> or <Files>. PR47765 [Eric Covener]

532 a put request (RFC 2616 14.16). PR 49825. [Stefan Fritsch]
534 *) mod_proxy: Release the backend connection as soon as EOS is detected,
535 so the backend isn't forced to wait for the client to eventually
536 acknowledge the data. [Graham Leggett]
538 *) mod_proxy: Optimise ProxyPass within a Location so that it is stored
539 per-directory, and chosen during the location walk. Make ProxyPass
540 work correctly from within a LocationMatch. [Graham Leggett]
542 *) core: Fix segfault if per-module LogLevel is on virtual host
543 scope. PR 50117. [Stefan Fritsch]
545 *) mod_proxy: Move the ProxyErrorOverride directive to have per
546 directory scope. [Graham Leggett]
548 *) mod_allowmethods: New module to deny certain HTTP methods without
549 interfering with authentication/authorization. [Paul Querna,
550 Igor Galić, Stefan Fritsch]

553 cert verification fails. PR 50093, PR 50094. [Lassi Tuura <lat cern ch>,
556 *) htcacheclean: Teach htcacheclean to limit cache size by number of
557 inodes in addition to size of files. Prevents a cache disk from
558 running out of space when many small files are cached.
561 *) core: Rename MaxRequestsPerChild to MaxConnectionsPerChild, which
562 describes more accurately what the directive does. The old name
563 still works but logs a warning. [Stefan Fritsch]
565 *) mod_cache: Optionally serve stale data when a revalidation returns a
566 5xx response, controlled by the CacheStaleOnError directive.
569 *) htcacheclean: Allow the listing of valid URLs within the cache, with
570 the option to list entry metadata such as sizes and times. [Graham
573 *) mod_cache: correctly parse quoted strings in cache headers.
576 *) mod_cache: Allow control over the base URL of reverse proxied requests
577 using the CacheKeyBaseURL directive, so that the cache key can be
578 calculated from the endpoint URL instead of the server URL. [Graham

664 mod_cache provider interface which is called to indicate to the
665 provider that caching is complete, giving the provider the opportunity
666 to commit temporary files permanently to the cache in an atomic
667 fashion. Replace the inconsistent use of error cleanups with a formal
668 set of pool cleanups attached to a subpool, which is destroyed on error.

1680 null value. [David Shane Holden <dpejesh apache.org>]
1682 *) core, authn/z: Determine registered authn/z providers directly in
1683 ap_setup_auth_internal(), which allows optional functions that just
1684 wrapped ap_list_provider_names() to be removed from authn/z modules.
1687 *) authn/z: Convert common provider version strings to macros.
1690 *) core: When testing for slash-terminated configuration paths in
1691 ap_location_walk(), don't look past the start of an empty string
1692 such as that created by a <Location ""> directive.
1695 *) core, mod_proxy: If a kept_body is present, it becomes safe for
1696 subrequests to support message bodies. Make sure that safety
1697 checks within the core and within the proxy are not triggered
1698 when kept_body is present. This makes it possible to embed
1699 proxied POST requests within mod_include. [Graham Leggett]
1701 *) mod_auth_form: Make sure the input filter stack is properly set
1702 up before reading the login form. Make sure the kept body filter
1703 is correctly inserted to ensure the body can be read a second
1704 time safely should the authn be successful. [Graham Leggett,
1707 *) mod_request: Insert the KEPT_BODY filter via the insert_filter
1708 hook instead of during fixups. Add a safety check to ensure the
1709 filters cannot be inserted more than once. [Graham Leggett,
1712 *) ap_cache_cacheable_headers_out() will (now) always
1713 merge an error headers _before_ clearing them and _before_
1714 merging in the actual entity headers and doing normal
1715 hop-by-hop cleansing. [Dirk-Willem van Gulik].
1717 *) cache: retire ap_cache_cacheable_hdrs_out() which was used
1718 for both in- and out-put headers; and replace it by a single
1719 ap_cache_cacheable_headers() wrapped in a in- and out-put
1720 specific ap_cache_cacheable_headers_in()/out(). The latter
1721 which will also merge error and ensure content-type. To keep
1722 cache modules consistent with ease. This API change bumps
1723 up the minor MM by one [Dirk-Willem van Gulik].
1725 *) Move the KeptBodySize directive, kept_body filters and the
1726 ap_parse_request_body function out of the http module and into a
1727 new module called mod_request, reducing the size of the core.
1730 *) mod_dbd: Handle integer configuration directive parameters with a
1733 *) Change the directives within the mod_session* modules to be valid
1734 both inside and outside the location/directory sections, as
1735 suggested by wrowe. [Graham Leggett]
1737 *) mod_auth_form: Add a module capable of allowing end users to log
1738 in using an HTML form, storing the credentials within mod_session.
1741 *) Add a function to the http filters that is able to parse an HTML
1742 form request with the type of application/x-www-form-urlencoded.
1745 *) mod_session_crypto: Initialise SSL in the post config hook.
1746 [Ruediger Pluem, Graham Leggett]
1748 *) mod_session_dbd: Add a session implementation capable of storing
1749 session information in a SQL database via the dbd interface. Useful
1750 for sites where session privacy is important. [Graham Leggett]
1752 *) mod_session_crypto: Add a session encoding implementation capable
1753 of encrypting and decrypting sessions wherever they may be stored.
1754 Introduces a level of privacy when sessions are stored on the
1755 browser. [Graham Leggett]
1757 *) mod_session_cookie: Add a session implementation capable of storing
1758 session information within cookies on the browser. Useful for high
1759 volume sites where server bound sessions are too resource intensive.
1762 *) mod_session: Add a generic session interface to unify the different
1763 attempts at saving persistent sessions across requests.
1766 *) core, authn/z: Avoid calling access control hooks for internal requests
1767 with configurations which match those of initial request. Revert to
1768 original behaviour (call access control hooks for internal requests
1769 with URIs different from initial request) if any access control hooks or
1770 providers are not registered as permitting this optimization.
1771 Introduce wrappers for access control hook and provider registration
1772 which can accept additional mode and flag data. [Chris Darroch]
1774 *) Introduced ap_expr API for expression evaluation.
1775 This is adapted from mod_include, which is the first module
1779 *) mod_authz_dbd: When redirecting after successful login/logout per
1780 AuthzDBDRedirectQuery, do not report authorization failure, and use
1781 first row returned by database query instead of last row.
1784 *) mod_ldap: Correctly return all requested attribute values
1785 when some attributes have a null value.

1794 *) Activate mod_cache, mod_file_cache and mod_disk_cache as part of the
1795 'most' set for '--enable-modules' and '--enable-shared-mods'. Include
1796 mod_mem_cache in 'all' as well. [Dirk-Willem van Gulik]
1798 *) Also install mod_so.h, mod_rewrite.h and mod_cache.h; as these
1799 contain public function declarations which are useful for
1800 third party module authors. PR 42431 [Dirk-Willem van Gulik].
1802 *) mod_dir, mod_negotiation: pass the output filter information
1803 to newly created sub requests; as these are later on used
1804 as true requests with an internal redirect. This allows for
1805 mod_cache et.al. to trap the results of the redirect.
1806 [Dirk-Willem van Gulik, Ruediger Pluem]
1808 *) mod_ldap: Add support (taking advantage of the new APR capability)
1809 for ldap rebind callback while chasing referrals. This allows direct
1810 searches on LDAP servers (in particular MS Active Directory 2003+)
1811 using referrals without the use of the global catalog.
1812 PRs 26538, 40268, and 42557 [Paul J. Reder]
1814 *) ApacheMonitor.exe: Introduce --kill argument for use by the
1815 installer. This will permit the installation tool to remove
1816 all running instances before attempting to remove the .exe.
1819 *) mod_ssl: Add support for OCSP validation of client certificates.
1820 PR 41123. [Marc Stern <marc.stern approach.be>, Joe Orton]
1822 *) mod_serf: New module for Reverse Proxying. [Paul Querna]
1824 *) core: Add the option to keep aside a request body up to a certain
1825 size that would otherwise be discarded, to be consumed by filters
1826 such as mod_include. When enabled for a directory, POST requests
1827 to shtml files can be passed through to embedded scripts as POST
1828 requests, rather being downgraded to GET requests. [Graham Leggett]

1843 parameters to the environment. Improve portability to
1844 EBCDIC machines by using apr_toupper(). [Martin Kraemer]
1846 *) mod_ldap, mod_authnz_ldap: Add support for nested groups (i.e. the ability
1847 to authorize an authenticated user via a "require ldap-group X" directive
1848 where the user is not in group X, but is in a subgroup contained in X.
1849 PR 42891 [Paul J. Reder]

1871 *) The LockFile directive, which specifies the location of
1872 the accept() mutex lockfile, is deprecated. Instead, the
1873 AcceptMutex directive now takes an optional lockfile
1874 location parameter, ala SSLMutex. [Jim Jagielski]
1876 *) mod_authn_dbd: Export any additional columns queried in the SQL select
1877 into the environment with the name AUTHENTICATE_<COLUMN>. This brings
1878 mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
1880 *) mod_dbd: Key the storage of prepared statements on the hex string
1881 value of server_rec, rather than the server name, as the server name
1882 may change (eg when the server name is set) at any time, causing
1883 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
1885 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
1887 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
1888 the first bucket from the brigade, finds it not to be a FILE
1889 bucket and barfs. The fix is to pass a bucket rather than a brigade.

1892 *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
1894 *) ap_get_server_version() has been removed. Third-party modules must
1895 now use ap_get_server_banner() or ap_get_server_description().
1898 *) All MPMs: Introduce a check_config phase between pre_config and
1899 open_logs, to allow modules to review interdependent configuration
1900 directive values and adjust them while messages can still be logged
1901 to the console. Handle relevant MPM directives during this phase
1902 and format messages for both the console and the error log, as
1903 appropriate. [Chris Darroch]
1905 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
1906 to circumvent the symbolic link checks imposed by FollowSymLinks and

1910 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
1911 The default is none as this is far greater debugging resolution than
1912 the typical administrator is prepared to untangle. [William Rowe]

1938 *) mod_charset_lite: Remove Content-Length when output filter can
1939 invalidate it. Warn when input filter can invalidate it.
1942 *) Authz: Add the new module mod_authn_core that will provide common
1943 authn directives such as 'AuthType', 'AuthName'. Move the directives
1944 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
1945 into mod_authn_core. [Brad Nicholes]
1947 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
1948 into the new module mod_access_compat which can be loaded to provide
1949 support for these directives.
1952 *) Authz: Move the 'Require' directive from the core module as well as
1953 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
1954 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
1955 logic into the authorization processing. [Brad Nicholes]
1957 *) Authz: Add the new module mod_authz_core which acts as the
1958 authorization provider vector and contains common authz
1959 directives. [Brad Nicholes]
1961 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
1962 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
1964 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
1965 host-based access control provided by mod_authz_host and invoked
1966 through the 'Require' directive. [Brad Nicholes]
1968 *) Authz: Convert all of the authz modules from hook based to

1978 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
1980 *) Asynchronous write completion for the Event MPM. [Brian Pane]
1982 *) Added an End-Of-Request bucket type. The logging of a request and
1983 the freeing of its pool are now done when the EOR bucket is destroyed.
1984 This has the effect of delaying the logging until right after the last
1985 of the response is sent; ap_core_output_filter() calls the access logger
1986 indirectly when it destroys the EOR bucket. [Brian Pane]
