-     Licensable by such Contributor to use, reproduce, make available,

- become effective for each Contribution on the date the Contributor first
- distributes such Contribution.
- .
- 2.3. Limitations on Grant Scope
- .
- The licenses granted in this Section 2 are the only rights granted under
- this License. No additional rights or licenses will be implied from the
- distribution or licensing of Covered Software under this License.
- Notwithstanding Section 2.1(b) above, no patent license is granted by a
- Contributor:
- .
- (a) for any code that a Contributor has removed from Covered Software;
-     or
- .
- (b) for infringements caused by: (i) Your and any other third party's
-     modifications of Covered Software, or (ii) the combination of its
-     Contributions with other software (except as part of its Contributor
-     Version); or
- .
- (c) under Patent Claims infringed by Covered Software in the absence of
-     its Contributions.
- .
- This License does not grant any rights in the trademarks, service marks,
- or logos of any Contributor (except as may be necessary to comply with
- the notice requirements in Section 3.4).
- .
- 2.4. Subsequent Licenses
- .
- No Contributor makes additional grants as a result of Your choice to
- distribute the Covered Software under a subsequent version of this
- License (see Section 10.2) or under the terms of a Secondary License (if
- permitted under the terms of Section 3.3).
- .
- 2.5. Representation

- Each Contributor represents that the Contributor believes its
- Contributions are its original creation(s) or it has sufficient rights
- to grant the rights to its Contributions conveyed by this License.
- .
- 2.6. Fair Use
- .
- This License is not intended to limit any rights You have under
- applicable copyright doctrines of fair use, fair dealing, or other

- .
- 3. Responsibilities
- -------------------
- .
- 3.1. Distribution of Source Form
- .
- All distribution of Covered Software in Source Code Form, including any
- Modifications that You create or to which You contribute, must be under
- the terms of this License. You must inform recipients that the Source
- Code Form of the Covered Software is governed by the terms of this
- License, and how they can obtain a copy of this License. You may not
- attempt to alter or restrict the recipients' rights in the Source Code
- Form.
- .
- 3.2. Distribution of Executable Form
- .
- If You distribute Covered Software in Executable Form then:
- .
- (a) such Covered Software must also be made available in Source Code
-     Form, as described in Section 3.1, and You must inform recipients of
-     the Executable Form how they can obtain a copy of such Source Code
-     Form by reasonable means in a timely manner, at a charge no more
-     than the cost of distribution to the recipient; and
- .
- (b) You may distribute such Executable Form under the terms of this
-     License, or sublicense it under different terms, provided that the
-     license for the Executable Form does not attempt to limit or alter
-     the recipients' rights in the Source Code Form under this License.
- .
- 3.3. Distribution of a Larger Work
- .
- You may create and distribute a Larger Work under terms of Your choice,
- provided that You also comply with the requirements of this License for
- the Covered Software. If the Larger Work is a combination of Covered
- Software with a work governed by one or more Secondary Licenses, and the
- Covered Software is not Incompatible With Secondary Licenses, this
- License permits You to additionally distribute such Covered Software
- under the terms of such Secondary License(s), so that the recipient of
- the Larger Work may, at their option, further distribute the Covered
- Software under the terms of either this License or such Secondary
- License(s).
- .
- 3.4. Notices
- .
- You may not remove or alter the substance of any license notices
- (including copyright notices, patent notices, disclaimers of warranty,
- or limitations of liability) contained within the Source Code Form of
- the Covered Software, except that You may alter any license notices to
- the extent required to remedy known factual inaccuracies.
- .
- 3.5. Application of Additional Terms
- .
- You may choose to offer, and to charge a fee for, warranty, support,
- indemnity or liability obligations to one or more recipients of Covered
- Software. However, You may do so only on Your own behalf, and not on
- behalf of any Contributor. You must make it absolutely clear that any
- such warranty, support, indemnity, or liability obligation is offered by
- You alone, and You hereby agree to indemnify every Contributor for any
- liability incurred by such Contributor as a result of warranty, support,
- indemnity or liability terms You offer. You may include additional
- disclaimers of warranty and limitations of liability specific to any
- jurisdiction.
- .
- 4. Inability to Comply Due to Statute or Regulation
- ---------------------------------------------------
- .
- If it is impossible for You to comply with any of the terms of this
- License with respect to some or all of the Covered Software due to
- statute, judicial order, or regulation then You must: (a) comply with
- the terms of this License to the maximum extent possible; and (b)
- describe the limitations and the code they affect. Such description must
- be placed in a text file included with all distributions of the Covered
- Software under this License. Except to the extent prohibited by statute
- or regulation, such description must be sufficiently detailed for a
- recipient of ordinary skill to be able to understand it.
- .
- 5. Termination
- --------------
- .
- 5.1. The rights granted under this License will terminate automatically
- if You fail to comply with any of its terms. However, if You become
- compliant, then the rights granted under this License from a particular
- Contributor are reinstated (a) provisionally, unless and until such
- Contributor explicitly and finally terminates Your grants, and (b) on an
- ongoing basis, if such Contributor fails to notify You of the
- non-compliance by some reasonable means prior to 60 days after You have
- come back into compliance. Moreover, Your grants from a particular
- Contributor are reinstated on an ongoing basis if such Contributor
- notifies You of the non-compliance by some reasonable means, this is the
- first time You have received notice of non-compliance with this License
- from such Contributor, and You become compliant prior to 30 days after
- Your receipt of the notice.
- .
- 5.2. If You initiate litigation against any entity by asserting a patent
- infringement claim (excluding declaratory judgment actions,
- counter-claims, and cross-claims) alleging that a Contributor Version
- directly or indirectly infringes any patent, then the rights granted to
- You by any and all Contributors for the Covered Software under Section
- 2.1 of this License shall terminate.
- .
- 5.3. In the event of termination under Sections 5.1 or 5.2 above, all
- end user license agreements (excluding distributors and resellers) which
- have been validly granted by You or Your distributors under this License
- prior to termination shall survive termination.

-  *  statutory, including, without limitation, warranties that the       *
-  *  Covered Software is free of defects, merchantable, fit for a        *
-  *  particular purpose or non-infringing. The entire risk as to the     *

-  *  (not any Contributor) assume the cost of any necessary servicing,   *

- -------------

 ==========================
 
+4.9.3, released 2017-06-02
+- Workaround PHP 7.1 infinite loop when opcode cache is enabled.
+  Thanks @Xiphin (#134, #135)
+- Don't use autoloader when testing for DOMDocument.  Hypothetically,
+  this could cause your install to start using DirectLex if you had
+  previously been monkeypatching in a custom, autoloaded implementation
+  of DOMDocument.  Don't do that.  Thanks @Izumi-kun (#130)
+
 4.9.2, released 2017-03-12
 - Fixes PHP 5.3 compatibility
 - Fix breakage when decoding decimal entities.  Thanks @rybakit (#129)

-4.9.0 was skipped due to a packaging problem; 4.9.2 fixes two
-major regressions in PHP 5.3 support and entity decoding; no
-other functional changes were applied.
+4.9.3 works around an infinite loop bug in PHP 7.1 with the opcode
+cache (and has one other, minor bugfix, avoiding using autoloading
+when testing for DOMDocument presence).  If these bugs do not
+affect you, you do not need to upgrade.
