That depends on several factors. Here are some pros and cons of each:

It is not recommended you do this because you may run into issues. For example, some changes were made in crypto_master.php and data/upgrader2.php prior to the first v11 alpha. These changes will result in a broken upgrade unless you already pulled these changes from git. Similar situations could happen in the future as well.

It is recommended you either discard the git install and use a fresh install from the Downloads, or to maintain a git install and a bleeding-edge release install separately. Do not combine the two.

Absolutely! Frequent changes may be made to both bundled and non-bundled addons. Bundled addons will be updated via the upgrader. For non-bundled addons, you will have to update them through the addons management screen (Admin Zone > Structure > Addons). You will be informed which ones need updated.

Once version 11 reaches release candidate, we do not expect frequent updates to non-bundled addons anymore. But it is still good practice to check after every update.

Yes, for basic non-custom v10 sites. However, expect some issues to arise in the process. And please report those issues to the tracker.

For v10 sites with non-bundled addons or customisations, upgrading to v11 will likely break the site until you update the non-bundled addons or temporarily remove the customisations.

We aim to have the upgrader fully functional for a large majority of types of sites and for sites using non-bundled addons by the time version 11 reaches release candidate stage.

We do not recommend upgrading production v10 sites at this time until v11 reaches stable.

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.

• 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.

• Content type: Choose to search specific content types like news, forum posts, or Comcode pages.
• Author/Submitter: Search for content submitted by a specific member.
• Date: Limit your search to content submitted within a specific time frame.
• Category (for certain content types): Narrow down your search to specific categories within a content type.

• Using the search bar in the header: This is the simplest way to search. Just type your search term in the box and click the search button.
• Using the 'Search' module: This module offers more detailed search options. You can access it via the 'site:search' page-link (usually under About > Search in the default menu).
• From the Forum: Click the 'Search' button on the forum or use the contextual search box on the forum member bar. This will search within your current forum or topic.
