      Upgrade may fail. Reporting:

      Problem: cannot install the best update candidate for package liboci8-zend-11.2.0.4-8.x86_64

        - nothing provides libaio.so.1 needed by liboci8-zend-21.1.0.0-25.x86_64

      To continue from such situation, liboci8-zend package (new version) should be installed manually.

      sudo yum install -y liboci8-zend

      Then restart the upgrade sequence from the step (including) that caused the error (re-run repository installer or other method you have chosen for ZendServer upgrade).

    Known problems (fix postponed):

    • php-fpm restart on Linux.
      Related to PHP version change through GUI. php-fpm processes do not restart automatically.
      As a workaround, php-fpm should be restarted manually from the console after switching PHP version

      sudo /usr/local/zend/bin/php-fpm.sh restart
    • JobQueue misbehavior during DST change (DST end in October).
      Jobs scheduled during the hour of DST change get executed large number of times.
      No known easy workaround. One option is to temporarily disable specific jobs for the specific DST change time period.

     

    Zend Server 2021.1.2 (March 2022)

    UPDATED to PHP 7.4.28

    • PHP 7.4.28: Fix #81708: UAF due to php_filter_float() failing for ints. Relevant for PHP 7.4 only (CVE-2021-21708)
    • Older PHP versions 7.1.33.12, 7.2.34.8 and 7.3.33 are updated and rebuilt with the latest timezone database.
    • For IBM i build, the freetds library is updated to new version 1.3.9
    • Windows installer update notification text change
    • Linux rpm repositories: Qt libraries package dependency fix for libicu.
    • Repository installer script displays correct Zend Server Web Ui port number (10101)

    Zend Server 2021.1.1 (December 2021)

    Updated PHP from 7.4.22 to 7.4.26

    • Core: Fixed bug #81518 (Header injection via default_mimetype / default_charset).
    • Date: Fixed bug #81500 (Interval serialization regression since 7.3.14 / 7.4.2).
    • MBString: Fixed bug #76167 (mbstring may use pointer from some previous request).
    • MySQLi: Fixed bug #81494 (Stopped unbuffered query does not throw error).
    • PCRE: Fixed bug #81424 (PCRE2 10.35 JIT performance regression).
    • Streams: Fixed bug #54340 (Memory corruption with user_filter).
    • XML: Fixed bug #79971 (special character is breaking the path in xml function). (CVE-2021-21707)

    Updated PHP from 7.3.29 to 7.3.33

    • XML: Fix #79971: special character is breaking the path in xml function. (CVE-2021-21707)

    Updated PHP from 7.2.34.4 to 7.2.34.8

    • Fix #79971: special character is breaking the path in xml function.

    Updated PHP from 7.1.33.8 to 7.1.33.12

    • Fix #79971: special character is breaking the path in xml function.

    Zend Server 2021.1.0 (September 2021)

    • Fixed Code Tracing that used a conflicting function flag value with PHP 7.4 when marking traceable PHP internal functions causing potential memory leaks. In addition, Code Tracing was including extra PHP internal functions in code traces that were not supposed to be there.
    • Added pdo_odbc extension for IBM i build. This module has a conflict with ibm_db2, pdo_ibm and odbc extensions. Which means that those listed modules MUST be disabled when pdo_odbc is in use or else php will crash due to conflicting symbols from libodbc and libdb400 dynamically loaded system libraries. In addition, to be noted that odbc extension (not pdo_odbc) is heavily modified in Zend Server IBM i build, not functionally equal to ZendPHP (community) variant, adding db2 features and linked to libdb400 library instead of libodbc. This has been like that for long time in Zend Server and we do not change that functionality now to be backwards compatible for customers who may be using odbc extension to communicate with db2 database. ZendPHP does not have such modifications, being functionally different - community variant.
    • ZSD automatically disables ibm_db2, pdo_ibm and odbc extensions when pdo_odbc extension is enabled from GUI. This is true the other way around: when either ibm_db2, pdo_ibm or odbc extension are enabled from GUI pdo_odbc is disabled automatically by ZSD. A NOTICE message is written to zsd.log file when this is done. The functionality is there to avoid PHP crash as explained in the previous bulletin. This functionality can not resolve conflicts when extension .ini files are modified manually in the file system.
    • Fix the functionality to create zendadmin user during automated installation process on IBM i
    • Fix Zend Server directory access permissions on IBM i
    • Improve installation sequence on IBM i. Moved version message initialization logic out from nativelibrary package into zend-server package to avoid errors in nativelibrary install program and to fix version message content in case of ZS upgrades.
    • Improve ZS daemons startup logic, now all processes are in proper IBM "namespaces" after ZS restart from web GUI.
    • Improve nativelib-zendphp74 package installation scripts for upgrades (ZS subsystem stop/(re)start logic).
    • Improve uninstall script for IBM i to avoid uninstalling of ZendPHP when using automated uninstall script for Zend Server
    • Improve IBM i version detection in RepositoryInstaller script.
    • Fix/improve gd extension on linux (PHP 7.1, 7.2, 7.3) and IBM i (PHP 7.2, 7.3) builds to support FreeType formats.
    • Update qt version to 5.12.11 (old 5.12.6)
    • Update PHP versions to 7.1.33.8, 7.2.34.4, 7.3.29, 7.4.22
    • Updated libpng from 1.6.32 to1.6.37 on Windows. This eliminates CVE: CVE-2019-7317 http://www.libpng.org/pub/png/libpng.html
    • Fix in IBMi ZS2021.1 installer so that incorrect "INVALID_LICENSE" message would not be generated with side by side install.
    • Fix warnings in log files on Windows platform caused by bad formatting in install-time SQL scripts.
    • Updated Oracle OCI libraries on linux platform. x64 uses now v21.1, ppc64 uses 19.3.
    • Updated sqlsrv version to 5.9.0 for PHP 7.3 and 7.4 on Linux.

    Known Issues

    • When you upgrade Zend Server on Windows, the installer leaves an extra entry under “Programs and Features” page, referencing the former version. If you uninstall Zend Server later, the extra entry will remain on the list of installed programs and cannot be removed by running the “uninstall” action. To manually remove the extra entry, you can edit the registry, search for “Zend Server” under registry keys “HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall” and “HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall”, then remove the key holding the uninstall data. For any questions or concerns, please contact Zend Server support.
