-experimental support for new platforms or preliminary versions of one or more
-new functionalities. The pre-release code may not be at the level of
-performance and compatibility of a final, generally available, product
-offering of the Licensed Software. The pre-release parts of the Licensed
-Software may not operate correctly, may contain errors and may be substantially
-modified by The Qt Company prior to the first commercial product release, if
-any. The Qt Company is under no obligation to make pre-release code
-commercially available, or provide any Support or Updates relating thereto. The
-Qt Company assumes no liability whatsoever regarding any pre-release code, but
-any use thereof is exclusively at Licensee's own risk and expense.
-
-6. LIMITED WARRANTY AND WARRANTY DISCLAIMER
-
-The Qt Company hereby represents and warrants that it has the power and
-authority to grant the rights and licenses granted to Licensee under this
-Agreement.
-
-Except as set forth above, the Licensed Software is licensed to Licensee
-"as is" and Licensee's exclusive remedy and The Qt Company's entire liability
-for errors in the Licensed Software shall be limited, at The Qt Company's
-option, to correction of the error, replacement of the Licensed Software or
-return of the applicable fees paid for the defective Licensed Software for the
-time period during which the License is not able to utilize the Licensed
-Software under the terms of this Agreement.
-
-TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE QT COMPANY ON BEHALF OF
-ITSELF AND ITS LICENSORS, SUPPLIERS AND AFFILIATES, DISCLAIMS ALL OTHER
-WARRANTIES, EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, ANY IMPLIED
-WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE AND NON-
-INFRINGEMENT WITH REGARD TO THE LICENSED SOFTWARE. THE QT COMPANY DOES NOT
-WARRANT THAT THE LICENSED SOFTWARE WILL SATISFY LICENSEE'S REQUIREMENTS OR THAT
-IT WILL OPERATE WITHOUT DEFECT OR ERROR OR THAT THE OPERATION THEREOF WILL BE
-UNINTERRUPTED. ALL USE OF AND RELIANCE ON THE LICENSED SOFTWARE IS AT THE SOLE
-RISK OF AND RESPONSIBILITY OF LICENSEE.

-NO EVENT SHALL EITHER PARTY'S TOTAL AGGREGATE LIABILITY UNDER THIS AGREEMENT
-EXCEED THE AGGREGATE LICENSE FEES PAID OR PAYABLE TO THE QT COMPANY FROM
-LICENSEE DURING THE PERIOD OF TWELVE (12) MONTHS IMMEDIATELY PRECEDING THE
-EVENT RESULTING IN SUCH LIABILITY.
-
-THE PROVISIONS OF THIS SECTION 7 ALLOCATE THE RISKS UNDER THIS AGREEMENT
-BETWEEN THE QT COMPANY AND LICENSEE AND THE PARTIES HAVE RELIED UPON THE
-LIMITATIONS SET FORTH HEREIN IN DETERMINING WHETHER TO ENTER INTO THIS AGREEMENT.
-
-7.2 Licensee's Indemnification
-
-Licensee shall indemnify and hold harmless The Qt Company from and against any
-claim, injury, judgment, settlement, loss or expense, including attorneys' fees

-Device (except where such cause of liability is solely attributable to the
-Licensed Software).

-any service or support to Customers.
-
-9. CONFIDENTIALITY
-
-Each Party acknowledges that during the Term of this Agreement each Party may
-receive information about the other Party's business, business methods,
-business plans, customers, business relations, technology, and other
-information, including the terms of this Agreement, that is confidential and
-of great value to the other Party, and the value of which would be
-significantly reduced if disclosed to third parties ("Confidential
-Information"). Accordingly, when a Party (the "Receiving Party") receives
-Confidential Information from the other Party (the "Disclosing Party"), the
-Receiving Party shall only disclose such information to employees and
-Contractors on a need to know basis, and shall cause its employees and
-employees of its Affiliates to: (i) maintain any and all Confidential
-Information in confidence; (ii) not disclose the Confidential Information to a
-third party without the Disclosing Party's prior written approval; and (iii)
-not, directly or indirectly, use the Confidential Information for any purpose
-other than for exercising its rights and fulfilling its responsibilities
-pursuant to this Agreement. Each Party shall take reasonable measures to
-protect the Confidential Information of the other Party, which measures shall
-not be less than the measures taken by such Party to protect its own
-confidential and proprietary information.
-
-Obligation of confidentiality shall not apply to information that (i) is or
-becomes generally known to the public through no act or omission of the
-Receiving Party; (ii) was in the Receiving Party's lawful possession prior to
-the disclosure hereunder and was not subject to limitations on disclosure or
-use; (iii) is developed independently by employees or Contractors of the
-Receiving Party or other persons working for the Receiving Party who have not
-had access to the Confidential Information of the Disclosing Party, as proven
-by the written records of the Receiving Party; (iv) is lawfully disclosed to
-the Receiving Party without restrictions, by a third party not under an
-obligation of confidentiality; or (v) the Receiving Party is legally compelled
-to disclose, in which case the Receiving Party shall notify the Disclosing
-Party of such compelled disclosure and assert the privileged and confidential
-nature of the information and cooperate fully with the Disclosing Party to
-limit the scope of disclosure and the dissemination of disclosed Confidential
-Information to the minimum extent necessary.
-
-The obligations under this Section 9 shall continue to remain in force for a
-period of five (5) years after the last disclosure, and, with respect to trade
-secrets, for so long as such trade secrets are protected under applicable trade
-secret laws.
-
-10. FEES, DELIVERY AND PAYMENT
-
-10.1 License Fees
-
-License Fees are described in The Qt Company's standard price list, quote or
-Purchase Order confirmation or in an appendix hereto, as the case may be.
-
-The License Fees shall not be refunded or claimed as a credit in any event or
-for any reason whatsoever.
-
-10.2 Ordering Licenses
-
-Licensee may purchase Development Licenses and Distribution Licenses pursuant
-to agreed pricing terms or, if no specific pricing terms have been agreed upon,
-at The Qt Company's standard pricing terms applicable at the time of purchase.
-
-Licensee shall submit all purchase orders for Development Licenses and
-Distribution Licenses to The Qt Company by email or any other method acceptable
-to The Qt Company (each such order is referred to herein as a "Purchase Order")
-for confirmation, whereupon the Purchase Order shall become binding between the
-Parties.
-
-10.3 Distribution License Packs
-
-Unless otherwise agreed, Distribution Licenses shall be purchased by way of
-Distribution License Packs.
-
-Upon due payment of the ordered Distribution License Pack(s), the Licensee will
-have an account of Distribution Licenses available for installing, bundling or
-integrating (all jointly "installing") the Redistributables with the Devices or
-for otherwise distributing the Redistributables in accordance with this
-Agreement.
-
-Each time Licensee "installs" or distributes a copy of Redistributables, then
-one Distribution License is used, and Licensee's account of available
-Distribution Licenses is decreased accordingly.
-
-Licensee may "install" copies of the Redistributables so long as Licensee has
-Distribution Licenses remaining on its account.
-
-Redistributables will be deemed to have been "installed" into a Device when one
-of the following circumstances shall have occurred: a) the Redistributables
-have been loaded onto the Device and used outside of the Licensee's premises or
-b) the Device has been fully tested and placed into Licensee's inventory
-(or sold) for the first time (i.e., Licensee will not be required to use
-(or pay for) more than one Distribution License for each individual Device,
-e.g. in a situation where a Device is returned to Licensee's inventory after
-delivery to a distributor or sale to a Customer). In addition, if Licensee
-includes a back-up copy of the Redistributables on a CD-ROM or other storage
-medium along with the product, that backup copy of the Redistributables will
-not be deemed to have been "installed" and will not require an additional
-Distribution License.
-
-10.4 Payment Terms
-
-License Fees and any other charges under this Agreement shall be paid by
-Licensee no later than thirty (30) days from the date of the applicable invoice
-from The Qt Company.
-
-The Qt Company will submit an invoice to Licensee after the date of this
-Agreement and/or after The Qt Company receives a Purchase Order from
-Licensee.
-

+2.0.3
+=====
+
+### Significant changes relative to 2.0.2:
+
+1. Fixed "using JNI after critical get" errors that occurred on Android
+platforms when passing invalid arguments to certain methods in the TurboJPEG
+Java API.
+
+2. Fixed a regression in the SIMD feature detection code, introduced by
+the AVX2 SIMD extensions (2.0 beta1[1]), that was known to cause an illegal
+instruction exception, in rare cases, on CPUs that lack support for CPUID leaf
+07H (or on which the maximum CPUID leaf has been limited by way of a BIOS
+setting.)
+
+3. The 4:4:0 (h1v2) fancy (smooth) chroma upsampling algorithm in the
+decompressor now uses a similar bias pattern to that of the 4:2:2 (h2v1) fancy
+chroma upsampling algorithm, rounding up or down the upsampled result for
+alternate pixels rather than always rounding down.  This ensures that,
+regardless of whether a 4:2:2 JPEG image is rotated or transposed prior to
+decompression (in the frequency domain) or after decompression (in the spatial
+domain), the final image will be similar.
+
+4. Fixed an integer overflow and subsequent segfault that occurred when
+attempting to compress or decompress images with more than 1 billion pixels
+using the TurboJPEG API.
+
+5. Fixed a regression introduced by 2.0 beta1[15] whereby attempting to
+generate a progressive JPEG image on an SSE2-capable CPU using a scan script
+containing one or more scans with lengths divisible by 16 would result in an
+error ("Missing Huffman code table entry") and an invalid JPEG image.
+
+6. Fixed an issue whereby `tjDecodeYUV()` and `tjDecodeYUVPlanes()` would throw
+an error ("Invalid progressive parameters") or a warning ("Inconsistent
+progression sequence") if passed a TurboJPEG instance that was previously used
+to decompress a progressive JPEG image.
+
+
+2.0.2
+=====
+
+### Significant changes relative to 2.0.1:
+
+1. Fixed a regression introduced by 2.0.1[5] that prevented a runtime search
+path (rpath) from being embedded in the libjpeg-turbo shared libraries and
+executables for macOS and iOS.  This caused a fatal error of the form
+"dyld: Library not loaded" when attempting to use one of the executables,
+unless `DYLD_LIBRARY_PATH` was explicitly set to the location of the
+libjpeg-turbo shared libraries.
+
+2. Fixed an integer overflow and subsequent segfault (CVE-2018-20330) that
+occurred when attempting to load a BMP file with more than 1 billion pixels
+using the `tjLoadImage()` function.
+
+3. Fixed a buffer overrun (CVE-2018-19664) that occurred when attempting to
+decompress a specially-crafted malformed JPEG image to a 256-color BMP using
+djpeg.
+
+4. Fixed a floating point exception that occurred when attempting to
+decompress a specially-crafted malformed JPEG image with a specified image
+width or height of 0 using the C version of TJBench.
+
+5. The TurboJPEG API will now decompress 4:4:4 JPEG images with 2x1, 1x2, 3x1,
+or 1x3 luminance and chrominance sampling factors.  This is a non-standard way
+of specifying 1x subsampling (normally 4:4:4 JPEGs have 1x1 luminance and
+chrominance sampling factors), but the JPEG format and the libjpeg API both
+allow it.
+
+6. Fixed a regression introduced by 2.0 beta1[7] that caused djpeg to generate
+incorrect PPM images when used with the `-colors` option.
+
+7. Fixed an issue whereby a static build of libjpeg-turbo (a build in which
+`ENABLE_SHARED` is `0`) could not be installed using the Visual Studio IDE.
+
+8. Fixed a severe performance issue in the Loongson MMI SIMD extensions that
+occurred when compressing RGB images whose image rows were not 64-bit-aligned.
+
+
+2.0.1
+=====
+
+### Significant changes relative to 2.0.0:
+
+1. Fixed a regression introduced with the new CMake-based Un*x build system,
+whereby jconfig.h could cause compiler warnings of the form
+`"HAVE_*_H" redefined` if it was included by downstream Autotools-based
+projects that used `AC_CHECK_HEADERS()` to check for the existence of locale.h,
+stddef.h, or stdlib.h.
+
+2. The `jsimd_quantize_float_dspr2()` and `jsimd_convsamp_float_dspr2()`
+functions in the MIPS DSPr2 SIMD extensions are now disabled at compile time
+if the soft float ABI is enabled.  Those functions use instructions that are
+incompatible with the soft float ABI.
+
+3. Fixed a regression in the SIMD feature detection code, introduced by
+the AVX2 SIMD extensions (2.0 beta1[1]), that caused libjpeg-turbo to crash on
+Windows 7 if Service Pack 1 was not installed.
+
+4. Fixed out-of-bounds read in cjpeg that occurred when attempting to compress
+a specially-crafted malformed color-index (8-bit-per-sample) Targa file in
+which some of the samples (color indices) exceeded the bounds of the Targa
+file's color table.
+
+5. Fixed an issue whereby installing a fully static build of libjpeg-turbo
+(a build in which `CFLAGS` contains `-static` and `ENABLE_SHARED` is `0`) would
+fail with "No valid ELF RPATH or RUNPATH entry exists in the file."
+
