<h4>Drastically reduce page updating time!</h4>
This WordPress plugin optimizes page management routines, it accelerates page saving time by bypassing the very heavy process of rebuilding all the rewriterules of your pretty-permalink enabled blogs each time anything on a page is changed.
When using WordPress as a CMS, it is not unusual to deal with web sites that have a lot of hierarchical pages. 
When reaching a few hundred pages and using custom or pretty SEO-aware permalinks, page updates become VERY slow.
Eventually, when reaching about 1000 pages, page management becomes quite tedious and time-consuming, because any change in a page takes a few minutes to be saved (during which the site usually comes to a halt because of heavy database load and table lock) 
when script or database max request times are finally reached, it becomes impossible to modify anything in a page.
The reason is that rewrite rules for all the blog’s pages are rebuilt everytime something is changed and saved in a page, even if the url structure has no reason to change at all.
(This is an aknowledged weakness of WordPress, that has been featured on the TRAC development list for a few years already)
This very short and simple plugin tries to fix this problem for most page updates: 
Rewriterules structure will get rebuilt only if the name of the page, or its parent attachment are changed, resulting in tremendous acceleration of the whole updating process.
Since version 0.2.0 you can decide for yourself when to force flushing of page address rewriterules, or when to completely disable rules flushing. 
Please take notice that if you disable the rules flushing, your new page addresses will not work until you force a bulk rules flush.
Expect hundred-fold improvement in page update delay in the admin for a 1000+ pages blog. 
(from over a minute to less than 10 seconds on one of my 2000+ page blog)

according to <a href="https://core.trac.wordpress.org/ticket/10852" rel="nofollow ugc">WP trac Ticket #10852</a>, you will possibly get even better performances.
(btw. I have another improvement of wp-includes/post.php that I could not yet figure out how to build into a plugin that makes me gain a few more seconds on each save.)
<h4>Possible caveat</h4>
This plugin chooses to bypass an important core function of the WordPress administration workflow for the sake of speed. 
Be aware that on some specific environments, this could cause unwanted side-effects, such as bad page linking or url permalink structure.
The plugin has however been tested on a 2000+ page medium-loaded site (around 1000 visitors/day) with 50 popular plugins installed and works perfectly for that purpose.
Your own mileage may vary.

<h4>Description en Français :</h4>
Ce plug-in WordPress accélère d’un facteur 100 ou plus le temps de sauvegarde ou mise à jour des pages hiérarchiques d’un blog WordPress comprenant un très grand nombre de pages (plusieurs centaines).
En effet, dès qu’on atteint quelques centaines de pages sur un blog orienté CMS, si on utilise des url “propres” compatibles avec l’optimisation du référencement (SEO), le temps de mise à jour des pages commence à prendre plusieurs minutes. 
L’administration des pages devient finalement impossible à cause d’une surcharge de la base de données ou de délais d’exécution trop importants.
Ce plugin règle le problème en évitant de reconstruire toute la structure des liens de toutes les pages du site si le nom de la page ou sa page de rattachement hiérarchique n’ont pas changé.
Le plugin peut fonctionner avec n’importe quelle langue ou jeu de caractères compatible avec WordPress.

Commentpress

CommentPress Core is an open source theme and plugin for WordPress that allows readers to comment in the margins of a text. Readers may comment paragraph-by-paragraph, line-by-line, block-by-block or by selecting text (coming soon to touch devices).
Annotate, gloss, workshop, debate: with CommentPress Core you can do all of these things on a finer-grained level, turning a document into a conversation. It can be applied to a fixed document (paper/essay/book etc.) or to a running blog. Use it in combination with BuddyPress and Groupblogs to create communities around your documents.
Please note: for the time-being, this plugin works best when the Gutenberg editor is disabled. If you want the simplest CommentPress experience in WordPress 5.x please install the Classic Editor or Gutenberg Ramp plugin to manage the post types on which the Gutenberg editor is enabled.
Please note: this plugin comes bundled with three official themes, one of which must be active for CommentPress Core to function. The “CommentPress Modern Theme” will be auto-activated when the plugin is first activated. The old “CommentPress Default Theme” is still included for those who wish to stay with it or have built their own child themes for it. Since version 3.9 a new “CommentPress Flat Theme” is included for those who want an alternative layout. If you are upgrading from a previous version of CommentPress (3.0.x – 3.3.x), please follow the instructions in the Installation section before doing so.
For further information and instructions please see the <a href="http://www.futureofthebook.org/commentpress/" rel="nofollow ugc">CommentPress website</a> or visit the plugin’s <a href="https://github.com/IFBook/commentpress-core" rel="nofollow ugc">GitHub repository</a>. Contact the developers by email at <a href="mailto:cpdev@futureofthebook.org" rel="nofollow ugc">cpdev@futureofthebook.org</a>.
For sites hosted in the European Union, please note: the “CommentPress Default Theme” makes use of cookies, but for presentational purposes only. If you intend to use the “CommentPress Default Theme” on a public site, you may need to inform visitors of this.
