[+] new feature
[-] bug resolved
[*] bug resolved and functionality improved
[+] IPv6 support. Parallels Plesk Panel now supports operations on IPv6 addresses (DNS, web hosting, mail, FTP and all other services). Administrators and resellers can offer service plans on IPv4, IPv6, or dual-stack subscriptions (one IPv4 + one IPv6 address).
The limitations of this new feature are as follows:
To learn more, see Administrator's Guide, the section Configuring Server IP Pool.
[+] (Only for Linux) SNI support. Panel for Linux allows using different SSL certificates for sites hosted on the same shared IP address. To achieve this, we added support for the Server Name Indication (SNI) extension to the Transport Layer Security protocol. This feature is available on the following operating systems:
Learn more about SNI in Administrator's Guide, the section Hosting Multiple SSL Sites on a Single IP Address (Linux Hosting).
[+] My webspaces in Server Administration Panel. Now it is easier for administrators to create own hosting accounts - so-called webspaces - with the Panels that also serve hosting customers and resellers. Panel lets administrators to run webspaces in Power User mode whereas operations over service plans and subscriptions remain in Server Administration Panel. Learn more about this mode in Administrator's Guide, section Switching to My Webspaces.
[+] Migration from Confixx and Parallels Pro Control Panel (Ensim Pro) Panel now supports migration of data from servers running Confixx and Parallels Pro Control Panel (formerly known as Ensim Pro). To learn more about migration specifics and limitations, refer to the corresponding sections (Confixx and Ensim Pro).
[+] Power User mode before initialization. Panel is capable of switching to Power User mode instantly after deployment whereas previously the mode choice was available only after the Panel initialization. This helps providers offer Power User mode directly with no input from customers. Read more in Deployment Guide, section Consider Switching to Power User Mode.
[+] (Only for Linux) Indication of installation/upgrade failures. If Panel fails to operate after installation or upgrade, it displays a special web page.
[+] (Only for Linux) Encrypted password in /etc/psa/.psa.shadow. The file .psa.shadow no longer contains the administrator's password in the plain-text format. Instead, this file contains an encrypted hash of the password. This improves the security level and prevents attempts to gain the administrative access to Panel by stealing the password.
This change does not anyhow affect typical commands that used the password. For example, you are free to run "mysql –uadmin –p`cat /etc/psa/.psa.shadow` psa". In case you wish to obtain the plain-text password, use the "/usr/local/psa/bin/admin --show-password" call.
[+] (Only for Linux) New unified installation and upgrade log. With this log, it is easier to troubleshoot system failures during installation or upgrade. If you use Parallels Installer, all log messages are stored in files /tmp/plesk_10.2.0_installation.log and /tmp/sitebuilder_5.2.0_installation.log. Error messages are available in files /tmp/plesk_10.2.0_installation_problems.log and /tmp/sitebuilder_5.2.0_installation_problems.log. The full log of Parallels Installer work is available at /tmp/autoinstaller3.log.
[+] Customer account without subscription. One of the typical cases is when a customer account is created to transfer subscriptions from other accounts. Now you can skip the time-consuming step of creating subscriptions for such accounts and instantly start transferring from other accounts. Learn more in Administrator's Guide, section Subscribing to Hosting Services.
[+] (Only for Linux) Adaptive restart interval for Apache. Previously, Apache restarted on each reconfiguration of web settings. Now administrators can set the web server to restart periodically. The configuration updates in this case will be accumulated and applied after the next restart. The new option is available on the Settings > Server Settings page.
[+] Get events by class and type through API RPC. The new API RPC protocol version supports fetching events by class and type. For more details, see the respective request packet structure.
[+] New Panel branding themes. Administrators can change the look and feel of Panel by downloading and installing branding themes (former skins). The themes are available at http://www.parallels.com/products/plesk/themes/.
[+] Support for new operating system versions. The following operating system versions are now supported:
RedHat Enterprise Linux 6
Debian GNU Linux 6
OpenSUSE 11.4
[+] Support for new browsers. Parallels Plesk Panel, SiteBuilder and Customer&Business Manager are compatible with Google Chrome 10, MS Internet Explorer 9, and Mozilla Firefox 4.
[*] Migration of SSL certificates. Now Plesk Migration Manager (PMM) correctly migrates SSL certificates.
[*] We improved readability of backup, restoration and migration reports. For easier troubleshooting, such reports are now output in human-readable format.
[*] On completion of the password retrieval procedure, Parallels Plesk Panel notifies about sending of password by e-mail.
[*] To facilitate the process of customizing Panel appearance with custom skins, the custom.css style sheet was added to all pages of Server Administration Panel.
[*] Error handling is improved in Settings > Mail Settings > White List in cases when administrator tries to add two entries with the same IP address.
[*] The loading time of page Tools & Utilities > IP Addresses is improved for servers with a lot of IP addresses (say, 500+).
[*] The pre9-backup-convert utility now automatically repairs invalid XML files: Fixes redundant tags (like <server>, <sa_confs> and <sa_conf>) and empty values in parameters (say, empty "enabled" attribute in <mailuser><properties><redirect> tag) in Plesk 8 backup dump.
[*] The "Domains" limit for resellers now defines the total of sites a reseller and their customers can own (previously, it applied only to sites of customers).
[*] The init_conf utility now supports the parameter –license_agreed to show or hide EULA (license agreement) during the initial configuration. Learn more about this utility in Command Line Reference(for Microsoft Windows or for Linux).

[+] Refined online stores A new look and feel of online stores makes it easier and faster to place orders. The store settings page is also refined: The most important options are displayed directly, while the rest are grouped into tabs. Learn more about online stores in Administrator’s Guide to Customer and Business Manager, the section Online Stores and Website Widgets.
[+] (Only for Linux) Single port for SSO and Panel. Single Sign-On service (SSO) on Linux now works on the same port, 8443, as Panel (instead of 11443 as in previous versions). This feature eliminates unnecessary SSL warnings when switching between Panel and Business Manager.
[+] IPv6 and dual-stack hosting support Now you can offer Plesk Panel hosting plans with IPv6 addresses or dual stack (both IPv4 and IPv6 addresses). This new ability brought the following changes to the Configuration Wizard, hosting plan properties, and panel settings (in server groups):
[+] Schet-facturas support The system is now capable of creating schet-facturas - documents that are required by accounting policies of some countries (such as Russia).

[+] Taxation configuration improvement: EU countries wildcard. Now you can have a single tax zone for all EU countries by using the EU wildcard instead of manually adding a tax zone per country. Read more about taxation in Administrator’s Guide to Customer and Business Manager, the section Configuring Taxation.
[*] Order eNom SSL certificates from Control Panel. Customers are able to complete the certificates ordering process right from Plesk Control Panel. All the data required by a registrar from customers is queried through To-Do items, so there is no necessity for customers to switch to a legacy panel to provide certificate-related details.
[*] Improvements to bank transfers. This release introduces a number of improvements to bank transfers management:
[*] Improvement: The page for adding new TLDs now suggests a list of top-level domains supported by selected registrar.
[-] Issue resolved: Customers failed to pay through Control Panel an invoice via third-party gateway (like PayPal) and encountered the error "Payment Error: Order form #1 'Français #1' has not primary and Bank Transfer payment gateway assigned" when no primary or bank transfer gateway was attached to the online store.
[-] Issue resolved: Because of improper database clean-up after service plan removal, administrator failed to sync with Panel (Server groups > PleskUnix > Sync All) and encountered the error "Error Message : 'Invalid attribute name: Product::$product_addon_group_id'".

[-] Issue resolved: Refunds were not reflected in the "Accounting Total" section of customer’s profile.
[+] Page URL modification (page slugs). SiteBuilder generates SEO-friendly website page URLs for all pages and allows users to modify these URLs.
[+] Links to own website pages. Users can quickly and conveniently create links to different pages of their own website.
[+] Embedded video module. SiteBuilder adds the Embedded Video module and supports usage of video URLs instead of embedded code for popular services like YouTube.
[+] Images as backgrounds. Users can upload their own images as a background of any part of their website.
[+] Transparent backgrounds. It is now possible to make the background of any website part completely transparent.
[+] Social Sharing module. Users can add Social Sharing module to their website, so that website visitors can share pages they like on social services like Facebook, Twitter and so on.
[+] Website snapshots. Every single action in SiteBuilder is immediately applied and saved, so if users are afraid of losing some data when removing modules or experimenting with website design, they can save current website state as a snapshot and revert to it at any time later.
[*] SiteBuilder over HTTP SiteBuilder operates over HTTP and occupies the 8880 port rather than the HTTPS port as before. It does not undermine security (since no sensitive data is passed to the application), but increases the convenience of using SiteBuilder in conjunction with the "Social Sharing" module.
[-] Issue resolved: During upgrade of SiteBuilder, some sites could not be upgraded, which made them non-editable in SiteBuilder.
[-] Issue resolved: Link editor incorrectly saved links to web pages.
[-] Issue resolved: Validation of CAPTCHA in contact forms always failed on the first attempt.

Parallels Plesk Panel Knowledge Base can be accessed at http://kb.parallels.com.
Note: PHP 5 is required for the brand new SiteBuilder.
You need to use Parallels Installer version 3.7.0 or later for performing upgrades to Parallels Plesk Panel 10.
MySQL server may hang during installation. If you encounter this issue, stop the installation, restart MySQL, and then start installation again.
If you want to install Miva applications on 64-bit Ubuntu Linux systems, then you also need to install 32-bit openssl libraries and specify the proper installation paths in the /etc/psa/psa.conf file, as LIB_SSL_PATH and LIB_CRYPTO_PATH values.
Installation of Parallels Plesk Panel 10 might fail on MySQL server restart. If you encounter this issue, restart MySQL manually, check if it accepts connections, and then start installation again.
You should specify a mail server you currently use with Panel when upgrading Panel through Virtuozzo templates; otherwise, the upgrade will fail. For details, see the KB article http://kb.parallels.com/en/11183.
Before you uprade from Plesk 8.6, ensure you have the latest version of PVC (4.6.0-212+). For details on problems you encounter if you use prior versions of PVC, see http://kb.parallels.com/en/11186.
In Virtuozzo environment, the IPv6 support on Ubuntu 8.04 (TLS) is provided only in Virtuozzo Containers 4.0 (and not provided in later versions).
To use spam protection based on DNS blackhole lists for IPv6 addresses, you should have Postfix v.2.6 or later.
hMailServer 4.x is not upgraded since the Panel 10 does not support this mail server. For the workaround, refer to http://kb.parallels.com/en/9602.
Customer and Business Manager is designed for the Administrator-Customers model and does not support the Panel resellers yet.
On operating systems of the SUSE family, Apache web server may fail to start/restart with the "could not bind to address [::]:443" error because some other process is using the 443 (80) port. For details on the problem resolution, refer to the KB article at http://kb.parallels.com/en/1507.
If web server fails to start and you see the lines "Unable to open logs" in the web server's error log file, then it means that the number of allowed open file descriptors is not enough for the number of hosted domains. In such a case, increase the number of file descriptors. You can use the following formula to calculate the required value: number of domains * 2 + 1024. The maximum possible value is 65536. To set the required value, use the ulimit -n <number> command.
Because of a bug in Mailman 2.1 software, mass addition or removal of mailing list subscribers might not work properly. To resolve this, you can switch off e-mail notifications by inserting the following lines into Mailman configuration file /etc/mailman/mm_cfg.py:DEFAULT_ADMIN_NOTIFY_MCHANGES = No
DEFAULT_SEND_WELCOME_MSG = No
DEFAULT_SEND_GOODBYE_MSG = No
