Yes (probably). Always remember especially during alpha and beta phases that things can break. Please make backups first. And let us know on the issue tracker if an issue occurs.
 

Note: You cannot upgrade from 11 alpha to 11 beta without first upgrading to 11.alpha4 (if you are not already on 11.alpha4).

As of July 22, 2024, we entered beta status where our focus is now smashing bugs and stabilising the software. All planned features have been implemented for 11.0 (and most others deferred to 11.1 or later), though we may still merge in a few minor features or tweaks. The upgrader has been tested on a typical non-custom v10 site.

We will be releasing several beta versions in the beta phase.

We do not know when we will be able to release the first Release Candidate or stable versions at this time.

These plans are all subject to change without notice.

• HTML Filtering: Configurable levels of filtering prevent malicious script injection.
• Content Security Policy (CSP): Restricts the sources from which scripts and other resources can be loaded.
• Input Sanitization: Data is sanitized before being processed to prevent malicious code execution.
• Output Encoding: Data displayed to users is properly encoded to prevent interpretation as active code.

• DODGY_GET_HACK: Suspicious URLs with potentially harmful characters.
• EVIL_POSTED_FORM_HACK: Possible CSRF attempts via malicious form submissions.
• SCRIPT_UPLOAD_HACK: Attempts to upload PHP scripts, potentially malicious.
• DOWNLOAD_PRIVATE_URL_HACK/TRY_TO_DOWNLOAD_SCRIPT: Attempts to download sensitive files.
• BRUTEFORCE_LOGIN_HACK: Repeated failed login attempts.
• SQL_INJECTION_HACK: Attempts to exploit SQL queries for data extraction.

• Avoid FTP: Use secure alternatives like SFTP or SSH for file transfer.
• Secure Email: Enable SSL for IMAP and POP3 email protocols.
• Strong Passwords: Use unique and complex passwords for different services.
• Secure Computers: Keep your own devices patched and secure.
• Maintenance Password: Remove the maintenance password from _config.php when not in use.

• Visual representation of password quality and enforcement of complexity rules.
• Password expiry and prevention of re-use.
• Secure password hashing, even if the database is compromised.
• Temporary passwords for staff setup.

• Two-factor authentication via IP address approval.
• IP address banning, including wildcard banning.
• Session locking to IP addresses.
• Configurable session expiry times.
• Ability to prevent privileged actions from auto-logged in sessions.
• Optional member approval process.

• Comprehensive audit logging of administrative actions.
• Logging of user actions and IP address history.
• Tools to analyze audit logs.
• Failed login logging.
• Hack attack detection, logging, and banning.
• Email notifications for changes to user credentials.

• Protection against CSRF attacks.
• Click-jacking prevention via CSP implementation.
• Secure coding standards and scanning techniques.
• Configurable HTML filtering to prevent XSS attacks.
• Secure code modularization standards.

• Granular privileges and access permissions.
• Content submission validation process.
• Rootkit detection system.
• Spam prevention systems.
• Web application firewall rules.
• Moderation systems.

• MySQL timeout setting: For MySQL 5.7+, set a query timeout to prevent searches from locking up your database. Composr automatically sets this, but you can configure it manually if needed.
• Use InnoDB tables: Switching to InnoDB tables in MySQL can prevent slow queries from affecting other users on your website. Note that InnoDB is not officially supported by Composr yet.
• Enable the fast custom index: As mentioned earlier, the fast custom index is optimized for handling large datasets and filtered searches, potentially leading to significant speed improvements.

• Use specific keywords: The more specific your keywords, the better your results.
• Use boolean operators: Use "+", "-", and quotation marks to refine your search.
• Optimize content titles and meta keywords: These fields are given priority during search, so make sure they accurately reflect your content.
• Consider enabling the fast custom index: Especially beneficial for large websites or frequent filtered searches.

• Faster filtered searches: Significantly improves search speed when you add filters like category or author.
• Configurable stop words: Control which common words are ignored during search.
• Better stemming: More accurately recognizes variations of words (e.g., "like" and "liking").
• Multilingual support: Indexes content based on different language translations.

• Slight lag in indexing new content: New content takes a short time to be indexed.
• Less accurate ranking: Ranking is based on the most obscure keyword, not a blend of all keywords.
• Cannot perform blank searches: You must enter at least one keyword.
