It might seem a little odd starting a blog on increasing Invision Community's speed with the word "lazy",  but I'll explain why this is a good word for performance shortly.
Earlier this year, Google announced that page speed is a ranking factor.
Simply put, if your site is slow, it will be ranked lower in Google's search results.
It is always a challenge making a large application like Invision Community as efficient as possible per page load. A single Invision Community page can pull in widgets from multiple applications as well as a lot of user-generated content with attachments, movies and images used heavily. 
This is where being lazy helps.
Lazy loading is a method by which attachments, embeds and images are not loaded by default. They are only loaded when the viewer scrolls down enough to make them visible.
This allows the page to load a good deal faster now it doesn't have to load megabytes of images before the page is shown as completely rendered.
I was going to take a fancy video showing it in action, but it's hard to capture as the system loads the media just before you get to it, so it looks fairly seamless, even with sluggish connections.

Not the most dynamic image, but this shows the placeholder retains the size of the image
In addition to image attachments, we have also added this lazy loading to maps and Twitter emoji images.
Improving non-image attachments
Once we had implemented the lazy loading framework, an area we wanted to improve was non-image attachments.
We have listened to a lot of the feedback we had on this area, and have now made it very clear when you add an attachment into a post. We've even returned the download count now it's being loaded on demand.

Using attachments when posting
All the letters
When we first implemented the letter avatars in 4.3, we discussed whether to use CSS styling or use an image.
We decided to go with an image as it was more stable over lots of different devices, including email.
We've revisited this in 4.4, and switched the letter avatars to SVG, which are much faster to render now that the browser doesn't have to load the image files.
Other performance improvements
We've taken a pass at most areas with an eye for performance, here is a list of the most significant items we've improved.
Several converter background tasks have been improved, so they work on less data Duplicate query for fetching clubs was removed in streams Notifications / follower management has been improved Member searches have been sped up (API, ACP live search, member list in ACP, mentions, etc.). Stream performance has been improved UTF8 conversions have been sped up Elasticsearch has been sped up by using pre-compiled queries and parameterisation, as well as the removal of view filtering (and tracking) HTTP/2 support with prefetch/preload has been added Several PHP-level performance improvements have been made Implemented rel=noopener when links open a new window (which improves browser memory management) Several other performance improvements for conversions were implemented that drastically reduce conversion time IP address lookups now fetch IP address details from us en-masse instead of one request per address Cache/data store management has been streamlined and centralised for efficiency Many background tasks and the profile sync functionality have all been improved for performance Brotli compression is now supported automatically if the server supports it Redis encryption can now be disabled if desired, which improves performance Phew, as you can see, we've spent a while tinkering under the hood too.
We'd love to hear your thoughts. Let us know below!
This blog is part of our series introducing new features for Invision Community 4.4.

We are happy to announce the new Invision Community 4.3 is available!
Some highlights in Invision Community 4.3 include...
Improved Search
We now support Elasticsearch for scalable and accurate searching that MySQL alone cannot provided. There are also enhancements to the overall search interfaces based on your feedback.

 
Emoji
Express yourself with native emoji support in all editors. You can also keep your custom emoticons as you have now.

 
Member Management
The AdminCP interface to manage your members is all new allowing you easier control and management of your membership.

 
Automatic Community Moderation
You as the administrator set up rules to define how many unique member reports a piece of content needs to receive before it's automatically hidden from view and moderators notified.

 
Clubs
The new Clubs feature has been a huge hit with Invision Community users and we are expanding it to include invite-only options, notifications, exposure on the main community pages, paid memberships, and more.
Custom Email Footers
Your community generates a lot of email and you can now include dynamic content in the footer to help drive engagement and content discovery. 
New Gallery Interface
We have reworked our Gallery system with a simplified upload process and more streamlined image viewing.
 
The full list follows. Enjoy!
Content Discovery
We now support Elasticsearch which is a search utility that allows for much faster and more reliable searching. The REST API now supports search functions. Both MySQL and Elasticsearch have new settings for the admin to use to set search-defaults and default content weighting to better customize search logic to your community. Visitors can now search for Content Pages and Commerce Products. When entering a search term, members now see a more clear interface so they know what areas they are searching in and the method of search. Member Engagement
Commerce can now send a customizable account welcome email after checkout. You can whitelist emails in the spam service to stop false-positives. REST API has many enhancements to mange members. Ability to join any OAuth service for login management. Invision Community can now be an OAuth endpoint. Wordpress OAuth login method built in. Support for Google's Invisible ReCaptcha. Groups can be excluded from Leaderboard (such as admins or bot groups). All emails generated by Invision Community can now contain admin-defined extra promotional text in the footer such as Our Picks, and Social Links. Admins can now define the order of Complete Your Profile to better control user experience. Clubs
Option to make a Club visible but invite-only Admins can set an option so any Club a member is part of will also show in the parent application. So if you are in a Club that has a Gallery tab then those image will show both in the Club and in the main Gallery section of the community. Club members can now follow an entire Club rather than just each content section. There is a new option on the Club directory page for a list view which is useful for communities with many Clubs. If you have Commerce you can now enable paid memberships to Clubs. Admins can set limits on number of Clubs per group. If a group has delete permission in their Club, they can now delete empty containers as well. Members can ignore invitations. Moderation and Administration
Unrestricted moderator or administrator permission sets in the AdminCP are visually flagged. This prevents administrator confusion when they cannot do something as they will be able to quickly see if their account has restrictions. You can choose to be notified with a new Club is created. Moderators can now reply to any content item with a hidden reply. Download screenshot/watermarks can now be rebuilt if you change settings. Support for Facebook Pixel to easily track visitors. Moderators can now delete Gallery albums. Automatic moderation tools with rules to define when content should auto-hide based on user reports. Totally new member management view in AdminCP. More areas are mass-selectable like comments and AdminCP functions for easier management. New Features
Commerce now has full Stripe support including fraud tools, Apple Pay, and other Stripe features. Commerce packages can now have various custom email events configured (expiring soon, purchased, expired). Full Emojii support in the editor. Complete overhaul of the Gallery upload and image views. Announcements system overhaul. Now global on all pages (not via widget) and new modes including dismissible announcements and top-header floating bar option. Many new reports on traffic and engagement in the AdminCP. Blog has new view modes to offer options for a traditional site blog or a community multi-member blog platform. The content-starter can now leave one reply to Reviews on their item. Commerce now makes it much easier to do basic account-subscriptions when there is no product attached. Useful Improvements
Forums has a new widget where you can filter by tags. If tags are not required, the tag input box now indicates this so the member knows they do not have to put in tags. Member cover photos can now be clicked to see the full image. Any item with a poll now has a symbol on the list view. Twitch.tv embed support. You can now update/overwrite media in the Pages Media Manager. Mapbox as an additional map provider to Google Maps. Technical Changes
Direct support for Sparkpost has been removed. Anyone currently using Sparkpost will automatically have their settings converted to the Sparkpost SMTP mode so your email will still work. Your cache engines (like Redis) will be checked on upgrade and in the support tool to ensure they are reachable. Third-party applications will now be visually labeled to distinguish them from Invision Community official applications. The queued tasks list in the AdminCP is now collapsed by default as queued tasks are not something people need to pay much attention to during normal operations. When upgrading from version 3 series you must convert your database to UTF8 and the system saves your original data in tables prefixed with orig. The AdminCP now alerts you these are still present and allows you to remove them to reclaim storage space. On new installs there are now reasonable defaults for upload limits to keep people from eating up storage space. Categories in all apps (forums, gallery albums, databases, etc.) no longer allow HTML in their titles. This has been a concern both in terms of security and usability so we were forced to restrict it. Large improvements to the Redis cache engine including use for sessions. The login with HTTPS option has been removed and those who were using it will be given instructions to convert their entire community to HTTPS. Images loaded through the proxy system now honor image limits for normal uploads. We now consider BBCode deprecated. We are not removing support but will not fix any future issues that may come up.
 
There's a lot to talk about here so we are going to lock this entry to comments so things do not get confusing. Feel free to comment on upcoming feature-specific entries or start a topic in our Feedback forum.
 

This entry is about our IPS Community Suite 4.2 release.
Sometimes you may find situations where you want to highlight one or more replies to a content item to bring attention to a really great response. This is especially true on busy communities where you might have dozens or even hundreds of replies in a single discussion.
There is now an ability for a moderator to Recommend a reply (or multiple replies) and even leave an optional note explaining why they think you should view that post.

Moderator Permission

Optional note for recommended reply
When a reply is Recommended you will see a snippet at the top of the content item along with the optional moderator note and a link to jump right to that reply.

A topic with a recommended reply.
You can Recommend more than one reply and this feature works through IPS Community Suite in forum topic, blog entries, gallery images, and so on. You can set this permission along with other moderator permissions in the AdminCP.
We really think this will allow moderators to bring attention to some of the best replies and guide users to the best content your community has to offer.

This entry is about our IPS Community Suite 4.2 release.
Following on from our previous entry about the new Recommended Replies feature, we also have one more small feature change that will be very useful.
Content Message is a small feature available in all IPS Community Suite content areas (forums, blogs, gallery, etc.) and allows a moderator to put a message at the top of any item.

Topic with a moderator message
This is useful if you have a special use for the area people are posting in, need to encourage conversation to stay on topic, or perhaps the conversation is becoming heated and you need to remind people to behave.
Sometimes the smallest features can prove the most useful and already I have found myself reaching for this feature out of habit from using it on our test 4.2 installs and missing it on our production site. I cannot wait to have it available and I am sure you will enjoy the ability to add custom notes to any area of the Suite.
 
Development Note
For our power users: this feature and the Recommended Replies feature use a new content meta data capability. This allows you to store miscellaneous data that is attached to a content item which does not need to be otherwise searched or exposed unless you are viewing that item. We will provide technical details on this later but it is a really easy way to store data about content without having to create additional tables or methods.

We are well into development on IPS Community Suite 4.2 and are excited to start announcing all the new features and improvements.
Our next big release is focused on engagement with your members. You will see enhancements to our Reputation system, new ways to encourage people to register on your community, and enhancements to existing features to make them more interactive. There are also entirely new capabilities we cannot wait to show you ranging from new ways to organize content to tools to help promote your community.
Version 4.2 also features a refreshed AdminCP and default front-end design. Theme changes in 4.2 are mostly in the CSS framework so your existing themes will either work without issue or require minor changes to work in the new version.
Over the next several weeks we will be posting news entries with previews of upcoming features fairly often. Be sure to follow our News section, our Facebook, or Twitter to stay up to date.
We expect IPS Community Suite 4.2 to be out in mid-2017 with a public preview available sooner.
Everyone at IPS has worked very hard on this update and we think you will love it!
