+2025.04.0 07.04.2025
+====================
+- Added support for applying multiple filters on individual interfaces - interface_libpcap_filter. See doc/voipmonitor.conf for detailed explanation. This option allows to overcome ~2.2M PPS on AWS or other virtualisations without using DPDK where software interrupts is the bottleneck [VS-1683]
+- DPDK: Added support for multiple RX queues. Parameter dpdk_nb_rxq now defaults to 2 - set it to 1 in case of issues.
+- server_destination parameter now accepts multiple IP addresses for failover (e.g., server_destination = 1.2.3.4, 5.6.7.8) [VS-1686].
+- Added support for MP3 audio format [VS-653].
+- Added parameters to configure jitter buffer properties: jitterbuffer_f1_jbsize, jitterbuffer_f1_resync_threshold, jitterbuffer_f2_jbsize, jitterbuffer_f2_resync_threshold, jitterbuffer_adapt_jbsize, jitterbuffer_adapt_resync_threshold, saveaudio_jitterbuffer_jbsize, saveaudio_jitterbuffer_resync_threshold [VS-1634]
+- Reduced frequency of logging the message: "packetbuffer: MEMORY IS FULL".
+- Added logging for asynchronous write queue length (tacQ).
+- Added source and destination IP addresses into RTCP graphs [VG-2957].
+- Removed length limitation for callid during merging [VS-1684].
+- Ensured maximum ID values from registration tables are read before starting interface data processing.
+- new options: sql_errors_log_file and sql_errors_skip.
+- Fixed potential crash in TLS when the cipher suite is not found.
+- Fixed potential conflict in the declaration of the strstr function [VS-1692].
+- Fixed memory leak occurring when the packet buffer block contains no valid packets (up to 20GB per week on some installations, present since version 2024.12) [VS-1691].
+- Fixed string limitation when opt_callidmerge_header is encrypted and exceeds 128 bytes.

 ====================
 - fix crash when creating audiograph - adding an error message handler to jpeg creation so that exit cannot be called [VS-1654]

 # To listen on both eth0 and eth1:

+# interface_libpcap_filter #
+# Defines custom libpcap filters per network interface, allowing traffic load distribution across multiple virtual 
+# interfaces, each handled by separate processing threads in VoIPmonitor. This significantly improves packet 
+# processing performance in high-traffic environments by parallelizing the capture and processing workload.
+# this is typically needed for AWS EC2 instances which has limits 2.2M packets per second per one libpcap 
+# instance (in this case DPDK should be better choice). 
+# whenever there is 100% si (software interrupts) in TOP when reading packets from the interface (which can be seen also by 
+# simply running tcpdump) you can use interface_libpcap_filter to split the traffic 
+# syntax: 
+# Multiple lines or semicolon-separated (;) entries are supported:
+#interface_libpcap_filter = <interface> : <libpcap_filter_expression>
+
+# When multiple filters are defined for the same physical interface using interface_libpcap_filter, 
+# VoIPmonitor internally creates multiple libpcap handler instances. Each handler independently applies its own 
+# filter and captures matched packets. However, libpcap itself does not create additional kernel threads per filter. 
+# Instead, VoIPmonitor initiates multiple user-space threads, each calling pcap_loop separately, thereby parallelizing 
+# packet reading and processing in user space. This approach helps distribute CPU load effectively across available cores, 
+# maximizing the packet processing capacity.
+
+#In this example, traffic on interface eth0 is divided into two separate capture streams, each with 
+# its own libpcap filter and processing thread.
